If the Node.js https API was used incorrectly and "undefined" was in passed for the "rejectUnauthorized" parameter, no error was returned and connections to servers with an expired certificate would have been accepted.
CVE-2020-28972 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2023-12-21 4.3 MEDIUM 5.9 MEDIUM
In SaltStack Salt before 3002.5, authentication to VMware vcenter, vsphere, and esxi servers (in the vmware.py files) does not always validate the SSL/TLS certificate.
CVE-2023-50454 1 Zammad 1 Zammad 2023-12-13 N/A 5.9 MEDIUM
An issue was discovered in Zammad before 6.2.0. In several subsystems, SSL/TLS was used to establish connections to external services without proper validation of hostname and certificate authority. This is exploitable by man-in-the-middle attackers.
CVE-2023-43082 1 Dell 3 Unity Operating Environment, Unity Xt Operating Environment, Unityvsa Operating Environment 2023-11-30 N/A 5.9 MEDIUM
Dell Unity prior to 5.3 contains a 'man in the middle' vulnerability in the vmadapter component. If a customer has a certificate signed by a third-party public Certificate Authority, the vCenter CA could be spoofed by an attacker who can obtain a CA-signed certificate.
CVE-2017-14419 1 Dlink 2 Dir-850l, Dir-850l Firmware 2023-11-17 4.3 MEDIUM 5.9 MEDIUM
The D-Link NPAPI extension, as used on D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. B (with firmware through FW208WWb02) devices, participates in mydlink Cloud Services by establishing a TCP relay service for HTTP, even though a TCP relay service for HTTPS is also established.
CVE-2017-14420 1 Dlink 2 Dir-850l, Dir-850l Firmware 2023-11-17 4.3 MEDIUM 5.9 MEDIUM
The D-Link NPAPI extension, as used on D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. B (with firmware through FW208WWb02) devices, does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2023-39441 1 Apache 3 Airflow, Apache-airflow-providers-imap, Apache-airflow-providers-smtp 2023-08-29 N/A 5.9 MEDIUM
Apache Airflow SMTP Provider before 1.3.0, Apache Airflow IMAP Provider before 3.3.0, and Apache Airflow before 2.7.0 are affected by the Validation of OpenSSL Certificate vulnerability. The default SSL context with SSL library did not check a server's X.509 certificate.  Instead, the code accepted any certificate, which could result in the disclosure of mail server credentials or mail contents when the client connects to an attacker in a MITM position. Users are strongly advised to upgrade to Apache Airflow version 2.7.0 or newer, Apache Airflow IMAP Provider version 3.3.0 or newer, and Apache Airflow SMTP Provider version 1.3.0 or newer to mitigate the risk associated with this vulnerability
CVE-2023-34410 1 Qt 1 Qt 2023-08-23 N/A 5.3 MEDIUM
An issue was discovered in Qt before 5.15.15, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.2. Certificate validation for TLS does not always consider whether the root of a chain is a configured CA certificate.
CVE-2023-38686 1 Matrix 1 Sydent 2023-08-10 N/A 5.3 MEDIUM
Sydent is an identity server for the Matrix communications protocol. Prior to version 2.5.6, if configured to send emails using TLS, Sydent does not verify SMTP servers' certificates. This makes Sydent's emails vulnerable to interception via a man-in-the-middle (MITM) attack. Attackers with privileged access to the network can intercept room invitations and address confirmation emails. This is patched in Sydent 2.5.6. When patching, make sure that Sydent trusts the certificate of the server it is connecting to. This should happen automatically when using properly issued certificates. Those who use self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of your operating system. As a workaround, one can ensure Sydent's emails fail to send by setting the configured SMTP server to a loopback or non-routable address under one's control which does not have a listening SMTP server.
CVE-2023-1055 2 Fedoraproject, Redhat 2 Fedora, Directory Server 2023-08-02 N/A 5.5 MEDIUM
A flaw was found in RHDS 11 and RHDS 12. While browsing entries LDAP tries to decode the userPassword attribute instead of the userCertificate attribute which could lead into sensitive information leaked. An attacker with a local account where the cockpit-389-ds is running can list the processes and display the hashed passwords. The highest threat from this vulnerability is to data confidentiality.
CVE-2023-28321 4 Apple, Fedoraproject, Haxx and 1 more 13 Macos, Fedora, Curl and 10 more 2023-08-02 N/A 5.9 MEDIUM
An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`.
CVE-2023-33201 1 Bouncycastle 1 Bc-java 2023-08-02 N/A 5.3 MEDIUM
Bouncy Castle For Java before 1.74 is affected by an LDAP injection vulnerability. The vulnerability only affects applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP search filter without any escaping, which leads to an LDAP injection vulnerability.
CVE-2020-16197 1 Octopus 2 Octopus Server, Server 2022-07-27 4.0 MEDIUM 4.3 MEDIUM
An issue was discovered in Octopus Deploy 3.4. A deployment target can be configured with an Account or Certificate that is outside the scope of the deployment target. An authorised user can potentially use a certificate that they are not in scope to use. An authorised user is also able to obtain certificate metadata by associating a certificate with certain resources that should fail scope validation.
CVE-2022-32210 1 Nodejs 1 Undici 2022-07-25 N/A 6.5 MEDIUM
`Undici.ProxyAgent` never verifies the remote server's certificate, and always exposes all request & response data to the proxy. This unexpectedly means that proxies can MitM all HTTPS traffic, and if the proxy's URL is HTTP then it also means that nominally HTTPS requests are actually sent via plain-text HTTP between Undici and the proxy server.
CVE-2022-22946 1 Vmware 1 Spring Cloud Gateway 2022-07-25 2.1 LOW 5.5 MEDIUM
In spring cloud gateway versions prior to 3.1.1+ , applications that are configured to enable HTTP2 and no key store or trusted certificates are set will be configured to use an insecure TrustManager. This makes the gateway able to connect to remote services with invalid or custom certificates.
CVE-2021-44532 1 Nodejs 1 Node.js 2022-07-25 5.0 MEDIUM 5.3 MEDIUM
Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.
CVE-2021-44533 1 Nodejs 1 Node.js 2022-07-25 5.0 MEDIUM 5.3 MEDIUM
Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 did not handle multi-value Relative Distinguished Names correctly. Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, for example, in order to inject a Common Name that would allow bypassing the certificate subject verification.Affected versions of Node.js that do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerable.
CVE-2021-22131 1 Fortinet 1 Fortitoken Mobile 2022-07-25 N/A 5.4 MEDIUM
A improper validation of certificate with host mismatch in Fortinet FortiTokenAndroid version 5.0.3 and below, Fortinet FortiTokeniOS version 5.2.0 and below, Fortinet FortiTokenWinApp version 4.0.3 and below allows attacker to retrieve information disclosed via man-in-the-middle attacks.
CVE-2020-15260 1 Teluu 1 Pjsip 2022-07-22 4.3 MEDIUM 6.8 MEDIUM
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In version 2.10 and earlier, PJSIP transport can be reused if they have the same IP address + port + protocol. However, this is insufficient for secure transport since it lacks remote hostname authentication. Suppose we have created a TLS connection to `sip.foo.com`, which has an IP address `100.1.1.1`. If we want to create a TLS connection to another hostname, say `sip.bar.com`, which has the same IP address, then it will reuse that existing connection, even though `100.1.1.1` does not have certificate to authenticate as `sip.bar.com`. The vulnerability allows for an insecure interaction without user awareness. It affects users who need access to connections to different destinations that translate to the same address, and allows man-in-the-middle attack if attacker can route a connection to another destination such as in the case of DNS spoofing.
CVE-2022-20813 1 Cisco 2 Expressway, Telepresence Video Communication Server 2022-07-14 4.3 MEDIUM 5.9 MEDIUM
Multiple vulnerabilities in the API and in the web-based management interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow a remote attacker to overwrite arbitrary files or conduct null byte poisoning attacks on an affected device. Note: Cisco Expressway Series refers to the Expressway Control (Expressway-C) device and the Expressway Edge (Expressway-E) device. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2019-5101 1 Openwrt 1 Openwrt 2022-06-21 4.3 MEDIUM 5.9 MEDIUM
An exploitable information leak vulnerability exists in the ustream-ssl library of OpenWrt, versions 18.06.4 and 15.05.1. When connecting to a remote server, the server's SSL certificate is checked but no action is taken when the certificate is invalid. An attacker could exploit this behavior by performing a man-in-the-middle attack, providing any certificate, leading to the theft of all the data sent by the client during the first request. After an SSL connection is initialized via _ustream_ssl_init, and after any data (e.g. the client's HTTP request) is written to the stream using ustream_printf, the code eventually enters the function __ustream_ssl_poll, which is used to dispatch the read/write events
CVE-2019-5102 1 Openwrt 1 Openwrt 2022-06-21 4.3 MEDIUM 5.9 MEDIUM
An exploitable information leak vulnerability exists in the ustream-ssl library of OpenWrt, versions 18.06.4 and 15.05.1. When connecting to a remote server, the server's SSL certificate is checked but no action is taken when the certificate is invalid. An attacker could exploit this behavior by performing a man-in-the-middle attack, providing any certificate, leading to the theft of all the data sent by the client during the first request.
CVE-2017-2913 1 Meetcircle 2 Circle With Disney, Circle With Disney Firmware 2022-06-13 2.6 LOW 5.9 MEDIUM
An exploitable vulnerability exists in the filtering functionality of Circle with Disney. SSL certificates for specific domain names can cause the Bluecoat library to accept a different certificate than intended. An attacker can host an HTTPS server with this certificate to trigger this vulnerability.
CVE-2022-26491 2 Debian, Pidgin 2 Debian Linux, Pidgin 2022-06-09 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Pidgin before 2.14.9. A remote attacker who can spoof DNS responses can redirect a client connection to a malicious server. The client will perform TLS certificate verification of the malicious domain name instead of the original XMPP service domain, allowing the attacker to take over control over the XMPP connection and to obtain user credentials and all communication content. This is similar to CVE-2022-24968.
CVE-2022-29082 1 Dell 1 Emc Networker 2022-06-08 4.9 MEDIUM 4.6 MEDIUM
Dell EMC NetWorker versions 19.1.x, 19.1.0.x, 19.1.1.x, 19.2.x, 19.2.0.x, 19.2.1.x 19.3.x, 19.3.0.x, 19.4.x, 19.4.0.x, 19.5.x,19.5.0.x, 19.6 and 19.6.0.1 and 19.6.0.2 contain an Improper Validation of Certificate with Host Mismatch vulnerability in Rabbitmq port 5671 which could allow remote attackers to spoof certificates.
CVE-2022-26766 1 Apple 6 Ipados, Iphone Os, Mac Os X and 3 more 2022-06-08 4.3 MEDIUM 5.5 MEDIUM
A certificate parsing issue was addressed with improved checks. This issue is fixed in tvOS 15.5, iOS 15.5 and iPadOS 15.5, Security Update 2022-004 Catalina, watchOS 8.6, macOS Big Sur 11.6.6, macOS Monterey 12.4. A malicious app may be able to bypass signature validation.
CVE-2022-22306 1 Fortinet 1 Fortios 2022-06-06 2.9 LOW 5.3 MEDIUM
An improper certificate validation vulnerability [CWE-295] in FortiOS 6.0.0 through 6.0.14, 6.2.0 through 6.2.10, 6.4.0 through 6.4.8, 7.0.0 may allow a network adjacent and unauthenticated attacker to man-in-the-middle the communication between the FortiGate and some peers such as private SDNs and external cloud platforms.
CVE-2017-2836 2 Debian, Freerdp 2 Debian Linux, Freerdp 2022-06-03 4.3 MEDIUM 5.9 MEDIUM
An exploitable denial of service vulnerability exists within the reading of proprietary server certificates in FreeRDP 2.0.0-beta1+android11. A specially crafted challenge packet can cause the program termination leading to a denial of service condition. An attacker can compromise the server or use man in the middle to trigger this vulnerability.
CVE-2022-1343 1 Openssl 1 Openssl 2022-06-02 4.3 MEDIUM 5.3 MEDIUM
The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. It is anticipated that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a certificate verification failure. The normal expected return value in this case would be 0. This issue also impacts the command line OpenSSL "ocsp" application. When verifying an ocsp response with the "-no_cert_checks" option the command line application will report that the verification is successful even though it has in fact failed. In this case the incorrect successful response will also be accompanied by error messages showing the failure and contradicting the apparently successful result. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).
CVE-2013-10001 1 Htc 5 Mail, One Sv, One X and 2 more 2022-06-01 4.3 MEDIUM 5.9 MEDIUM
A vulnerability was found in HTC One/Sense 4.x. It has been rated as problematic. Affected by this issue is the certification validation of the mail client. An exploit has been disclosed to the public and may be used.

IBM Sterling Secure Proxy 6.0.3 and IBM Secure External Authentication Server 6.0.3 does not properly ensure that a certificate is actually associated with the host due to improper validation of certificates. IBM X-Force ID: 201104.
CVE-2021-27768 1 Hcltech 1 Verse 2022-05-24 4.3 MEDIUM 5.9 MEDIUM
Using the ability to perform a Man-in-the-Middle (MITM) attack, which indicates a lack of hostname verification, sensitive account information was able to be intercepted. In this specific scenario, the application's network traffic was intercepted using a proxy server set up in 'transparent' mode while a certificate with an invalid hostname was active. The Android application was found to have hostname verification issues during the server setup and login flows; however, the application did not process requests post-login.
CVE-2018-8356 1 Microsoft 13 .net Core, .net Framework, .net Framework Developer Pack and 10 more 2022-05-23 2.1 LOW 5.5 MEDIUM

CVE-2022-24968 1 Mellium 1 Xmpp 2022-02-22 4.3 MEDIUM 5.9 MEDIUM
In Mellium mellium.im/xmpp through 0.21.0, an attacker capable of spoofing DNS TXT records can redirect a WebSocket connection request to a server under their control without causing TLS certificate verification to fail. This occurs because the wrong host name is selected during this verification.
CVE-2020-24661 2 Fedoraproject, Gnome 2 Fedora, Geary 2022-02-22 2.6 LOW 5.9 MEDIUM
GNOME Geary before 3.36.3 mishandles pinned TLS certificate verification for IMAP and SMTP services using invalid TLS certificates (e.g., self-signed certificates) when the client system is not configured to use a system-provided PKCS#11 store. This allows a meddler in the middle to present a different invalid certificate to intercept incoming and outgoing mail.
CVE-2022-24320 1 Schneider-electric 3 Clearscada, Ecostruxure Geo Scada Expert 2019, Ecostruxure Geo Scada Expert 2020 2022-02-16 4.3 MEDIUM 5.9 MEDIUM

In Preloader XFLASH, there is a possible escalation of privilege due to an improper certificate validation. This could lead to local escalation of privilege for an attacker who has physical access to the device with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06160806; Issue ID: ALPS06160806.
CVE-2021-34558 3 Fedoraproject, Golang, Netapp 5 Fedora, Go, Cloud Insights Telegraf and 2 more 2022-02-07 2.6 LOW 6.5 MEDIUM
The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.
CVE-2015-4100 1 Puppet 1 Puppet Enterprise 2022-01-24 4.9 MEDIUM 6.8 MEDIUM
Puppet Enterprise 3.7.x and 3.8.0 might allow remote authenticated users to manage certificates for arbitrary nodes by leveraging a client certificate trusted by the master, aka a "Certificate Authority Reverse Proxy Vulnerability."
CVE-2021-39359 1 Gnome 1 Libgda 2021-12-31 4.3 MEDIUM 5.9 MEDIUM
In GNOME libgda through 6.0.0, gda-web-provider.c does not enable TLS certificate verification on the SoupSessionSync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.
CVE-2020-7942 1 Puppet 2 Puppet, Puppet Agent 2021-12-30 4.0 MEDIUM 6.5 MEDIUM
Previously, Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the `default` node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting `strict_hostname_checking = true` in `puppet.conf` on your Puppet master. Puppet 6.13.0 and 5.5.19 changes the default behavior for strict_hostname_checking from false to true. It is recommended that Puppet Open Source and Puppet Enterprise users that are not upgrading still set strict_hostname_checking to true to ensure secure behavior. Affected software versions: Puppet 6.x prior to 6.13.0 Puppet Agent 6.x prior to 6.13.0 Puppet 5.5.x prior to 5.5.19 Puppet Agent 5.5.x prior to 5.5.19 Resolved in: Puppet 6.13.0 Puppet Agent 6.13.0 Puppet 5.5.19 Puppet Agent 5.5.19
CVE-2021-39365 2 Debian, Gnome 2 Debian Linux, Grilo 2021-12-16 4.3 MEDIUM 5.9 MEDIUM
In GNOME grilo though 0.3.13, grl-net-wc.c does not enable TLS certificate verification on the SoupSessionAsync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.
CVE-2021-32728 2 Debian, Nextcloud 2 Debian Linux, Nextcloud 2021-12-16 4.0 MEDIUM 6.5 MEDIUM
The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server with a computer. Clients using the Nextcloud end-to-end encryption feature download the public and private key via an API endpoint. In versions prior to 3.3.0, the Nextcloud Desktop client fails to check if a private key belongs to previously downloaded public certificate. If the Nextcloud instance serves a malicious public key, the data would be encrypted for this key and thus could be accessible to a malicious actor. This issue is fixed in Nextcloud Desktop Client version 3.3.0. There are no known workarounds aside from upgrading.
CVE-2020-4496 2 Ibm, Linux 2 Spectrum Protect Plus, Linux Kernel 2021-12-15 4.3 MEDIUM 5.9 MEDIUM
