| CVE-2023-28366 | 1 Eclipse | 1 Mosquitto | 2024-01-07 | N/A | 7.5 HIGH |
| The broker in Eclipse Mosquitto 1.3.2 through 2.x before 2.0.16 has a memory leak that can be abused remotely when a client sends many QoS 2 messages with duplicate message IDs, and fails to respond to PUBREC commands. This occurs because of mishandling of EAGAIN from the libc send function. | |||||
| CVE-2023-3592 | 1 Eclipse | 1 Mosquitto | 2024-01-07 | N/A | 7.5 HIGH |
| In Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types. | |||||
| CVE-2021-41039 | 1 Eclipse | 1 Mosquitto | 2021-12-03 | 5.0 MEDIUM | 7.5 HIGH |
| In versions 1.6 to 2.0.11 of Eclipse Mosquitto, an MQTT v5 client connecting with a large number of user-property properties could cause excessive CPU usage, leading to a loss of performance and possible denial of service. | |||||
| CVE-2017-7655 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2021-11-02 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto version from 1.0 to 1.4.15, a Null Dereference vulnerability was found in the Mosquitto library which could lead to crashes for those applications using the library. | |||||
| CVE-2021-34432 | 1 Eclipse | 1 Mosquitto | 2021-08-17 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto versions 2.07 and earlier, the server will crash if the client tries to send a PUBLISH packet with topic length = 0. | |||||
| CVE-2018-20145 | 1 Eclipse | 1 Mosquitto | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| Eclipse Mosquitto 1.5.x before 1.5.5 allows ACL bypass: if the option per_listener_settings was set to true, and the default listener was in use, and the default listener specified an acl_file, then the acl file was being ignored. | |||||
| CVE-2018-12551 | 1 Eclipse | 1 Mosquitto | 2019-10-09 | 6.8 MEDIUM | 8.1 HIGH |
| When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use a password file for authentication, any malformed data in the password file will be treated as valid. This typically means that the malformed data becomes a username and no password. If this occurs, clients can circumvent authentication and get access to the broker by using the malformed username. In particular, a blank line will be treated as a valid empty username. Other security measures are unaffected. Users who have only used the mosquitto_passwd utility to create and modify their password files are unaffected by this vulnerability. | |||||
| CVE-2018-12550 | 1 Eclipse | 1 Mosquitto | 2019-10-09 | 6.8 MEDIUM | 8.1 HIGH |
| When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use an ACL file, and that ACL file is empty, or contains only comments or blank lines, then Mosquitto will treat this as though no ACL file has been defined and use a default allow policy. The new behaviour is to have an empty ACL file mean that all access is denied, which is not a useful configuration but is not unexpected. | |||||
| CVE-2018-12543 | 1 Eclipse | 1 Mosquitto | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto versions 1.5 to 1.5.2 inclusive, if a message is published to Mosquitto that has a topic starting with $, but that is not $SYS, e.g. $test/test, then an assert is triggered that should otherwise not be reachable and Mosquitto will exit. | |||||
| CVE-2017-7651 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto 1.4.14, a user can shutdown the Mosquitto server simply by filling the RAM memory with a lot of connections with large payload. This can be done without authentications if occur in connection phase of MQTT protocol. | |||||
| CVE-2017-7652 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2019-10-09 | 6.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto 1.4.14, if a Mosquitto instance is set running with a configuration file, then sending a HUP signal to server triggers the configuration to be reloaded from disk. If there are lots of clients connected so that there are no more file descriptors/sockets available (default limit typically 1024 file descriptors on Linux), then opening the configuration file will fail. | |||||
| CVE-2017-7654 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto 1.4.15 and earlier, a Memory Leak vulnerability was found within the Mosquitto Broker. Unauthenticated clients can send crafted CONNECT packets which could cause a denial of service in the Mosquitto Broker. | |||||
