https://notcve.org/view.php?id=CVE-2022-47631
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
https://notcve.org/view.php?id=CVE-2023-32683
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 •
CVSS: 6.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-39374 – Synapse Denial of service due to incorrect application of event authorization rules during state resolution
https://notcve.org/view.php?id=CVE-2022-39374
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 •
CVSS: 5.0EPSS: 0%CPEs: 1EXPL: 0CVE-2022-39335 – Synapse does not apply enough checks to servers requesting auth events of events in a room
https://notcve.org/view.php?id=CVE-2022-39335
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.

27 Jan 2023 — Razer Synapse before 3.7.0830.081906 allows privilege escalation due to an unsafe installation path, improper privilege management, and improper certificate validation. Attackers can place malicious 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 the malicious DLLs are unsigned, it suffices to use self-signed DLLs. The validity of the DLL signatures is not checked.

https://notcve.org/view.php?id=CVE-2022-41952
22 Nov 2022 — Synapse before 1.52.0 with URL preview functionality enabled will attempt to generate URL previews for media stream URLs without properly limiting connection time. Connections will only be terminated after `max_spider_size` (default: 10M) bytes have been downloaded, which can in some cases lead to long-lived connections towards the streaming media server (for instance, Icecast). This can cause excessive traffic and connections toward such servers if their stream URL is, for example, posted to a large room w... • https://github.com/matrix-org/synapse/pull/11784 • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2022-31152
02 Sep 2022 — Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. The Matrix specification specifies a list of [event authorization rules](https://spec.matrix.org/v1.2/rooms/v9/#authorization-rules) which must be checked when determining if an event should be accepted into a room. In versions of Synapse up to and including version 1.61.0, some of these rules are not correctly applied. An attacker could craft events which would be accepted by Synapse but not a spec-conformant s... • https://github.com/matrix-org/synapse/pull/13087 • CWE-703: Improper Check or Handling of Exceptional Conditions CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2022-31052
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 •
