CVSS: 4.3EPSS: 0%CPEs: 3EXPL: 0CVE-2023-42453 – Improper validation of receipts allows forged read receipts in matrix synapse
https://notcve.org/view.php?id=CVE-2023-42453
26 Sep 2023 — Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. Users were able to forge read receipts for any event (if they knew the room ID and event ID). Note that the users were not able to view the events, but simply mark it as read. This could be confusing as clients will show the event as read by the user, even if they are not in the room. This issue has been patched in version 1.93.0. • https://github.com/matrix-org/synapse/pull/16327 • CWE-285: Improper Authorization •

14 Sep 2023 — Razer Synapse through 3.7.1209.121307 allows privilege escalation due to an unsafe installation path and improper privilege management. Attackers can place DLLs into %PROGRAMDATA%\Razer\Synapse3\Service\bin if they do so before the service is installed and if they deny write access for the SYSTEM user. Although the service will not start if it detects malicious DLLs in this directory, attackers can exploit a race condition and replace a valid DLL (i.e., a copy of a legitimate Razer DLL) with a malicious DLL... • https://packetstorm.news/files/id/174696 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-32683 – URL deny list bypass via oEmbed and image URLs when generating previews in Synapse

06 Jun 2023 — Synapse is a Matrix protocol homeserver written in Python with the Twisted framework. A discovered oEmbed or image URL can bypass the `url_preview_url_blacklist` setting potentially allowing server side request forgery or bypassing network policies. Impact is limited to IP addresses allowed by the `url_preview_ip_range_blacklist` setting (by default this only allows public IPs) and by the limited information returned to the client: 1. For discovered oEmbed URLs, any non-JSON response or a JSON response whic... • https://github.com/matrix-org/synapse/pull/15601 • CWE-863: Incorrect Authorization CWE-918: Server-Side Request Forgery (SSRF) •

06 Jun 2023 — Synapse is a Matrix protocol homeserver written in Python with the Twisted framework. In affected versions it may be possible for a deactivated user to login when using uncommon configurations. This only applies if any of the following are true: 1. JSON Web Tokens are enabled for login via the `jwt_config.enabled` configuration setting. 2. The local password database is enabled via the `password_config.enabled` and `password_config.localdb_enabled` configuration settings *and* a user's password is updated v... • https://github.com/matrix-org/synapse/pull/15624 • CWE-287: Improper Authentication •

26 May 2023 — Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. If Synapse and a malicious homeserver are both joined to the same room, the malicious homeserver can trick Synapse into accepting previously rejected events into its view of the current state of that room. This can be exploited in a way that causes all further messages and state changes sent in that room from the vulnerable homeserver to be rejected. This issue has been patched in version 1.68.0 Synapse es un se... • https://github.com/matrix-org/synapse/pull/13723 • CWE-400: Uncontrolled Resource Consumption •

26 May 2023 — Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. The Matrix Federation API allows remote homeservers to request the authorization events in a room. This is necessary so that a homeserver receiving some events can validate that those events are legitimate and permitted in their room. However, in versions of Synapse up to and including 1.68.0, a Synapse homeserver answering a query for authorization events does not sufficiently check that the requesting server s... • https://github.com/matrix-org/synapse/issues/13288 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •

26 May 2023 — Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. A malicious user on a Synapse homeserver X with permission to create certain state events can disable outbound federation from X to an arbitrary homeserver Y. Synapse instances with federation disabled are not affected. In versions of Synapse up to and including 1.73, Synapse did not limit the size of `invite_room_state`, meaning that it was possible to create an arbitrarily large invite event.

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') •
