2DescriptionCVE.org
AVideo through commit c91b5975d contains a cross-site request forgery and path traversal vulnerability in stopLive.php that allows attackers to delete directories by exploiting missing token validation and unsanitized key parameter concatenation. Attackers can craft an image tag with a traversal payload like key=../../videos to trigger recursive deletion of the videos directory when an admin visits a malicious page.
AnalysisAI
Cross-site request forgery chained with path traversal in AVideo's stopLive.php enables attackers to trigger recursive deletion of arbitrary server directories when an authenticated administrator visits a malicious page. The vulnerability exists through commit c91b5975d of the WWBN AVideo self-hosted video platform, affecting all versions covered by CPE cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that an authenticated AVideo administrator visit an attacker-controlled page while holding an active session cookie to the target AVideo instance - the CSRF mechanism relies on the browser automatically attaching session credentials to the cross-origin request. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:H) accurately reflects the core threat model: network-accessible exploitation with no attacker privileges required, but contingent on an authenticated admin visiting a malicious page (UI:P). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update AVideo to a commit after c91b5975d as directed by the vendor security advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-qqhx-ccvr-97q7. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a complete inventory of AVideo instances and restrict administrative interface access to internal networks only; disable any external web access to admin panels and issue administrator alerts regarding phishing risks associated with this vulnerability. …
