Unauthenticated Video File Access in AVideo Platform

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains an unauthenticated file read vulnerability in the getRecordedFile.php endpoint that streams recorded FLV files from the temporary directory. Attackers can request the endpoint with a known or guessed stream key to download recorded live video files without authentication or authorization checks.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

WWBN AVideo contains a critical authentication bypass vulnerability in its getRecordedFile.php endpoint that allows unauthenticated attackers to download recorded live video files directly from the server's temporary directory. By simply knowing or guessing a stream key, adversaries can bypass all authentication and authorization mechanisms to access sensitive recorded content—including private streams, confidential meetings, or user-generated video data. This vulnerability affects any organization deploying AVideo for live streaming, video conferencing, or content distribution, with particular risk to enterprises using it for internal communications or remote work scenarios where recorded sessions may contain proprietary or personal information.

Casky's 283 matched skills leverage Claude's reasoning capabilities to identify the attack chains underlying this vulnerability across MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would observe detection patterns revealing: (1) unauthenticated HTTP requests to /getRecordedFile.php with varying stream key parameters, indicating reconnaissance or brute-force attempts; (2) successful file streaming responses returning FLV video data without prior session authentication tokens; (3) lateral reconnaissance probing temporary directories for discoverable file patterns. The platform's extended reasoning would correlate these indicators to expose the root cause—missing authorization checks in a file-serving endpoint—and map specific exploitation techniques, enabling security teams to distinguish legitimate video access from unauthorized exfiltration attempts in their logs and network traffic.
