CVSS: 7.3EPSS: 0%CPEs: 2EXPL: 3CVE-2021-44226 – Razer Synapse 3.6.x DLL Hijacking
https://notcve.org/view.php?id=CVE-2021-44226
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. The unprivileged user may have placed Trojan horse DLLs there. Razer Synapse versiones anteriores a 3.7.0228.022817, permite una escalada de privilegios porque es basado en %PROGRAMDATA%\Razer\Synapse3\Service\bin incluso si %PROGRAMDATA%\Razer ha sido creado por cualquier usuario no privilegiado antes de la instalación de Synapse. El usuario no privilegiado puede haber colocado allí DLLs troyanos Razer Synapse versions prior to 3.7.0228.022817 suffer from a dll hijacking vulnerability. • http://packetstormsecurity.com/files/166485/Razer-Synapse-3.6.x-DLL-Hijacking.html http://packetstormsecurity.com/files/170772/Razer-Synapse-3.7.0731.072516-Local-Privilege-Escalation.html http://packetstormsecurity.com/files/174696/Razer-Synapse-Race-Condition-DLL-Hijacking.html http://seclists.org/fulldisclosure/2022/Mar/51 http://seclists.org/fulldisclosure/2023/Jan/26 http://seclists.org/fulldisclosure/2023/Sep/6 https://www.razer.com/community https://www.syss.de/fileadmin/dokumente/Publikationen& • CWE-427: Uncontrolled Search Path Element •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-41281 – Path traversal in Matrix Synapse
https://notcve.org/view.php?id=CVE-2021-41281
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 https://github.com/matrix-org/synapse/releases/tag/v1.47.1 https://github.com/matrix-org/synapse/security/advisories/GHSA-3hfw-x7gx-437c https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EU7QRE55U4IUEDLKT5IYPWL3UXMELFAS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/N3WY56LCEZ4ZECLWV5KMAXF2PSMUB4F2 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 3.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-39164 – Improper authorisation of /members discloses room membership to non-members
https://notcve.org/view.php?id=CVE-2021-39164
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 https://github.com/matrix-org/synapse/releases/tag/v1.41.1 https://github.com/matrix-org/synapse/security/advisories/GHSA-3x4c-pq33-4w3q https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2VHDEPCZ22GJFMZCWA2XZAGPOEV72POF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PXT7ID7DNBRN2TVTETU3SYQHJKEG6PXN • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2021-39163
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 information in the database or using the admin API. • https://github.com/matrix-org/synapse/commit/cb35df940a https://github.com/matrix-org/synapse/releases/tag/v1.41.1 https://github.com/matrix-org/synapse/security/advisories/GHSA-jj53-8fmw-f2w2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2VHDEPCZ22GJFMZCWA2XZAGPOEV72POF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PXT7ID7DNBRN2TVTETU3SYQHJKEG6PXN • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-863: Incorrect Authorization •
CVSS: 5.3EPSS: 0%CPEs: 2EXPL: 0CVE-2021-29471 – Denial of service in Matrix Synapse
https://notcve.org/view.php?id=CVE-2021-29471
Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.33.2 "Push rules" can specify conditions under which they will match, including `event_match`, which matches event content against a pattern including wildcards. Certain patterns can cause very poor performance in the matching engine, leading to a denial-of-service when processing moderate length events. The issue is patched in version 1.33.2. • https://github.com/matrix-org/synapse/commit/03318a766cac9f8b053db2214d9c332a977d226c https://github.com/matrix-org/synapse/releases/tag/v1.33.2 https://github.com/matrix-org/synapse/security/advisories/GHSA-x345-32rc-8h85 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TNNAJOZNMVMXM6AS7RFFKB4QLUJ4IFEY • CWE-331: Insufficient Entropy CWE-400: Uncontrolled Resource Consumption •
