CVE-2023-48795 42 Apache, Apple, Asyncssh Project and 39 more 68 Sshd, Sshj, Macos and 65 more 2024-01-11 N/A 5.9 MEDIUM
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust.
CVE-2023-6927 1 Redhat 2 Keycloak, Single Sign-on 2024-01-09 N/A 6.1 MEDIUM
A flaw was found in Keycloak. This issue may allow an attacker to steal authorization codes or tokens from clients using a wildcard in the JARM response mode "form_post.jwt" which could be used to bypass the security patch implemented to address CVE-2023-6134.
CVE-2023-6134 1 Redhat 2 Keycloak, Single Sign-on 2023-12-29 N/A 5.4 MEDIUM
A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.
CVE-2023-6563 1 Redhat 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more 2023-12-27 N/A 7.7 HIGH
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2022-1274 1 Redhat 8 Enterprise Linux, Enterprise Linux For Ibm Z Systems, Enterprise Linux For Ibm Z Systems Eus and 5 more 2023-12-22 N/A 5.4 MEDIUM
A flaw was found in Keycloak in the execute-actions-email endpoint. This issue allows arbitrary HTML to be injected into emails sent to Keycloak users and can be misused to perform phishing or other attacks against users.
CVE-2023-0264 1 Redhat 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more 2023-08-14 N/A 5.0 MEDIUM
A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate requests.

This issue could impact confidentiality, integrity, and availability.
CVE-2022-1245 1 Redhat 1 Keycloak 2022-07-15 7.5 HIGH 9.8 CRITICAL
A privilege escalation flaw was found in the token exchange feature of keycloak.

A vulnerability was found in keycloak, where path traversal using URL-encoded path segments in the request is possible because the resources endpoint applies a transformation of the url path to the file path. Only few specific folder hierarchies can be exposed by this flaw
CVE-2019-14910 1 Redhat 1 Keycloak 2020-10-09 7.5 HIGH 9.8 CRITICAL
A vulnerability was found in keycloak 7.x, when keycloak is configured with LDAP user federation and StartTLS is used instead of SSL/TLS from the LDAP server (ldaps), in this case user authentication succeeds even if invalid password has entered.
