CVSS: 6.5EPSS: 2%CPEs: 3EXPL: 0CVE-2022-31052 – URL previews can crash Synapse media repositories or Synapse monoliths

28 Jun 2022 — Synapse is an open source home server implementation for the Matrix chat network. In versions prior to 1.61.1 URL previews of some web pages can exhaust the available stack space for the Synapse process due to unbounded recursion. This is sometimes recoverable and leads to an error for the request causing the problem, but in other cases the Synapse process may crash altogether. It is possible to exploit this maliciously, either by malicious users on the homeserver, or by remote users sending URLs that a loc... • https://github.com/matrix-org/synapse/commit/fa1308061802ac7b7d20e954ba7372c5ac292333 • CWE-674: Uncontrolled Recursion •

23 Mar 2022 — Razer Synapse before 3.7.0228.022817 allows privilege escalation because it relies on %PROGRAMDATA%\Razer\Synapse3\Service\bin even if %PROGRAMDATA%\Razer has been created by any unprivileged user before Synapse is installed.

CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-41281 – Path traversal in Matrix Synapse
https://notcve.org/view.php?id=CVE-2021-41281
23 Nov 2021 — Synapse is a package for Matrix homeservers written in Python 3/Twisted. Prior to version 1.47.1, Synapse instances with the media repository enabled can be tricked into downloading a file from a remote server into an arbitrary directory. No authentication is required for the affected endpoint. The last 2 directories and file name of the path are chosen randomly by Synapse and cannot be controlled by an attacker, which limits the impact. Homeservers with the media repository disabled are unaffected. • https://github.com/matrix-org/synapse/commit/91f2bd090 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

31 Aug 2021 — Matrix is an ecosystem for open federated Instant Messaging and Voice over IP. In versions 1.41.0 and prior, unauthorised users can access the membership (list of members, with their display names) of a room if they know the ID of the room. The vulnerability is limited to rooms with `shared` history visibility. Furthermore, the unauthorised user must be using an account on a vulnerable homeserver that is in the room. Server administrators should upgrade to 1.41.1 or later in order to receive the patch. • https://github.com/matrix-org/synapse/commit/cb35df940a • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-863: Incorrect Authorization •

31 Aug 2021 — Matrix is an ecosystem for open federated Instant Messaging and Voice over IP. In versions 1.41.0 and prior, unauthorised users can access the name, avatar, topic and number of members of a room if they know the ID of the room. This vulnerability is limited to homeservers where the vulnerable homeserver is in the room and untrusted users are permitted to create groups (communities). By default, only homeserver administrators can create groups. However, homeserver administrators can already access this infor... • https://github.com/matrix-org/synapse/commit/cb35df940a • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-863: Incorrect Authorization •

11 Dec 2017 — In Apache Synapse, by default no authentication is required for Java Remote Method Invocation (RMI). So Apache Synapse 3.0.1 or all previous releases (3.0.0, 2.1.0, 2.0.0, 1.2, 1.1.2, 1.1.1) allows remote code execution attacks that can be performed by injecting specially crafted serialized objects. And the presence of Apache Commons Collections 3.2.1 (commons-collections-3.2.1.jar) or previous versions in Synapse distribution makes this exploitable. To mitigate the issue, we need to limit RMI access to tru... • https://github.com/HuSoul/CVE-2017-15708 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
