| CVE-2021-29431 | 1 Matrix | 1 Sydent | 2021-04-22 | 4.0 MEDIUM | 6.5 MEDIUM |
| Sydent is a reference Matrix identity server. Sydent can be induced to send HTTP GET requests to internal systems, due to lack of parameter validation or IP address blacklisting. It is not possible to exfiltrate data or control request headers, but it might be possible to use the attack to perform an internal port enumeration. This issue has been addressed in in 9e57334, 8936925, 3d531ed, 0f00412. A potential workaround would be to use a firewall to ensure that Sydent cannot reach internal HTTP resources. | |||||
| CVE-2020-26891 | 1 Matrix | 1 Synapse | 2020-10-26 | 4.3 MEDIUM | 6.1 MEDIUM |
| AuthRestServlet in Matrix Synapse before 1.21.0 is vulnerable to XSS due to unsafe interpolation of the session GET parameter. This allows a remote attacker to execute an XSS attack on the domain Synapse is hosted on, by supplying the victim user with a malicious URL to the /_matrix/client/r0/auth/*/fallback/web or /_matrix/client/unstable/auth/*/fallback/web Synapse endpoints. | |||||
| CVE-2019-18835 | 1 Matrix | 1 Synapse | 2020-08-24 | 7.5 HIGH | 9.8 CRITICAL |
| Matrix Synapse before 1.5.0 mishandles signature checking on some federation APIs. Events sent over /send_join, /send_leave, and /invite may not be correctly signed, or may not come from the expected servers. | |||||
| CVE-2018-12423 | 1 Matrix | 1 Synapse | 2019-10-02 | 5.0 MEDIUM | 7.5 HIGH |
| In Synapse before 0.31.2, unauthorised users can hijack rooms when there is no m.room.power_levels event in force. | |||||
| CVE-2018-16515 | 2 Debian, Matrix | 2 Debian Linux, Synapse | 2019-10-02 | 6.5 MEDIUM | 8.8 HIGH |
| Matrix Synapse before 0.33.3.1 allows remote attackers to spoof events and possibly have unspecified other impacts by leveraging improper transaction and event signature validation. | |||||
| CVE-2018-12291 | 1 Matrix | 1 Synapse | 2019-10-02 | 5.0 MEDIUM | 7.5 HIGH |
| The on_get_missing_events function in handlers/federation.py in Matrix Synapse before 0.31.1 has a security bug in the get_missing_events federation API where event visibility rules were not applied correctly. | |||||
| CVE-2019-11842 | 1 Matrix | 2 Sydent, Synapse | 2019-05-10 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Matrix Sydent before 1.0.3 and Synapse before 0.99.3.1. Random number generation is mishandled, which makes it easier for attackers to predict a Sydent authentication token or a Synapse random ID. | |||||
| CVE-2019-11340 | 1 Matrix | 1 Sydent | 2019-04-22 | 4.3 MEDIUM | 5.9 MEDIUM |
| util/emailutils.py in Matrix Sydent before 1.0.2 mishandles registration restrictions that are based on e-mail domain, if the allowed_local_3pids option is enabled. This occurs because of potentially unwanted behavior in Python, in which an email.utils.parseaddr call on user@bad.example.net@good.example.com returns the user@bad.example.net substring. | |||||
| CVE-2018-10657 | 1 Matrix | 1 Synapse | 2018-06-07 | 5.0 MEDIUM | 7.5 HIGH |
| Matrix Synapse before 0.28.1 is prone to a denial of service flaw where malicious events injected with depth = 2^63 - 1 render rooms unusable, related to federation/federation_base.py and handlers/message.py, as exploited in the wild in April 2018. | |||||
| CVE-2004-2089 | 1 Matrix | 1 Matrix Ftp Server | 2017-07-10 | 5.0 MEDIUM | N/A |
