DescriptionCVE.org

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 is missing an authentication/authorization check in plugin/WebRTC/status.json.php. When the WebRTC plugin is present, any unauthenticated remote user can request /plugin/WebRTC/status.json.php and receive JSON containing the absolute filesystem path of the WebRTC2RTMP helper binary (revealing the document-root path), the configured WebRTC port, file_exists/is_executable status for the binary, the contents of the WebRTC log/JSON files (videos/WebRTC2RTMP.log) when present, and whether the configured port is reachable on loopback (127.0.0.1) and on the public address. The endpoint performs no User::isLogged(), User::isAdmin(), or forbiddenPage() check. The issue was unfixed at the time of reporting.

AnalysisAI

Unauthenticated information disclosure in AVideo's WebRTC plugin exposes sensitive server-side configuration data to any remote user. When the WebRTC plugin is installed, the /plugin/WebRTC/status.json.php endpoint responds with the absolute filesystem path of the WebRTC2RTMP binary (revealing document-root layout), the configured WebRTC port, binary existence and executability status, WebRTC log file contents, and TCP reachability results for both loopback and the public address. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the AVideo WebRTC plugin be installed and present on the target server - instances without this plugin do not expose the vulnerable endpoint. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 6.9 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L) accurately reflects a network-reachable, unauthenticated information-disclosure flaw with limited direct confidentiality impact - no credentials or private media content are exposed. … 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 No vendor-released patch has been identified at time of analysis - the issue was unfixed when reported. … Detailed patch versions, workarounds, and compensating controls in full report.
