CVSS: 6.1EPSS: 0%CPEs: 1EXPL: 0CVE-2022-41965 – Opencast Authenticated OpenRedirect Vulnerability
https://notcve.org/view.php?id=CVE-2022-41965
Opencast is a free, open-source platform to support the management of educational audio and video content. Prior to Opencast 12.5, Opencast's Paella authentication page could be used to redirect to an arbitrary URL for authenticated users. The vulnerability allows attackers to redirect users to sites outside of one's Opencast install, potentially facilitating phishing attacks or other security issues. This issue is fixed in Opencast 12.5 and newer. Opencast es una plataforma gratuita de código abierto para respaldar la gestión de contenido educativo de audio y video. • https://github.com/opencast/opencast/commit/d2ce2321590f86b066a67e8c231cf68219aea017 https://github.com/opencast/opencast/security/advisories/GHSA-r3qr-vwvg-43f7 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-29237 – Limited Authentication Bypass for Media Files in Opencast
https://notcve.org/view.php?id=CVE-2022-29237
Opencast is a free and open source solution for automated video capture and distribution at scale. Prior to Opencast 10.14 and 11.7, users could pass along URLs for files belonging to organizations other than the user's own, which Opencast would then import into the current organization, bypassing organizational barriers. Attackers must have full access to Opencast's ingest REST interface, and also know internal links to resources in another organization of the same Opencast cluster. Users who do not run a multi-tenant cluster are not affected by this issue. This issue is fixed in Opencast 10.14 and 11.7. • https://github.com/opencast/opencast/commit/8d5ec1614eed109b812bc27b0c6d3214e456d4e7 https://github.com/opencast/opencast/security/advisories/GHSA-qm6v-cg9v-53j3 • CWE-287: Improper Authentication •
CVSS: 9.9EPSS: 0%CPEs: 1EXPL: 2CVE-2021-43821 – Files Accessible to External Parties in Opencast
https://notcve.org/view.php?id=CVE-2021-43821
Opencast is an Open Source Lecture Capture & Video Management for Education. Opencast before version 9.10 or 10.6 allows references to local file URLs in ingested media packages, allowing attackers to include local files from Opencast's host machines and making them available via the web interface. Before Opencast 9.10 and 10.6, Opencast would open and include local files during ingests. Attackers could exploit this to include most local files the process has read access to, extracting secrets from the host machine. An attacker would need to have the privileges required to add new media to exploit this. • https://github.com/Jackey0/opencast-CVE-2021-43821-env https://github.com/opencast/opencast/blob/69952463971cf578363e3b97d8edaf334ff51253/modules/ingest-service-impl/src/main/java/org/opencastproject/ingest/impl/IngestServiceImpl.java#L1587 https://github.com/opencast/opencast/commit/65c46b9d3e8f045c544881059923134571897764 https://github.com/opencast/opencast/security/advisories/GHSA-59g4-hpg3-3gcp https://mvnrepository.com/artifact/org.opencastproject/opencast-ingest-service-impl • CWE-552: Files or Directories Accessible to External Parties •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 1CVE-2021-43807 – HTTP Method Spoofing in Opencast
https://notcve.org/view.php?id=CVE-2021-43807
Opencast is an Open Source Lecture Capture & Video Management for Education. Opencast versions prior to 9.10 allow HTTP method spoofing, allowing to change the assumed HTTP method via URL parameter. This allows attackers to turn HTTP GET requests into PUT requests or an HTTP form to send DELETE requests. This bypasses restrictions otherwise put on these types of requests and aids in cross-site request forgery (CSRF) attacks, which would otherwise not be possible. The vulnerability allows attackers to craft links or forms which may change the server state. • https://github.com/opencast/opencast/commit/59cb6731067283e54f15462be38b6117d8b9ea8b#diff-9c5fb3d1b7e3b0f54bc5c4182965c4fe1f9023d449017cece3005d3f90e8e4d8 https://github.com/opencast/opencast/commit/8f8271e1085f6f8e306c689d6a56b0bb8d076444 https://github.com/opencast/opencast/security/advisories/GHSA-j4mm-7pj3-jf7v • CWE-290: Authentication Bypass by Spoofing •
