CVE-2025-34438: CWE-639 Authorization Bypass Through User-Controlled Key in World Wide Broadcast Network AVideo
AVideo versions prior to 20.1 contain an insecure direct object reference vulnerability allowing users with upload permissions to modify the rotation metadata of any video. The endpoint verifies upload capability but fails to enforce ownership or management rights for the targeted video.
AI Analysis
Technical Summary
CVE-2025-34438 affects AVideo by World Wide Broadcast Network and involves an authorization bypass through a user-controlled key. Specifically, users who have upload permissions can exploit an insecure direct object reference vulnerability to alter the rotation metadata of videos they do not own or manage. The endpoint responsible for this action validates only the upload permission but fails to enforce proper authorization checks on video ownership or management rights, allowing unauthorized modification of video metadata.
Potential Impact
An attacker with upload permissions can modify the rotation metadata of any video, potentially leading to unauthorized changes in video presentation. This could affect content integrity and user experience but does not directly indicate broader system compromise or data leakage. The CVSS score of 5.3 reflects a medium impact level.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided at this time. Until a patch is available, restrict upload permissions to trusted users only and monitor for unauthorized metadata changes where possible.
