WWBN AVideo: Unauthenticated Arbitrary Image Read via Path Traversal in `view/img/image404Raw.php`

Noroxi assessment

Priority: Monitor (action score 27/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.58% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

WWBN AVideo is an open source video platform. In 29.0 and earlier, an unauthenticated remote attacker can read arbitrary image files anywhere on disk that the PHP user can open — including private user-profile photos that the application's normal serving wrappers gate behind ACLs, admin-uploaded thumbnails, encrypted-video poster frames, and image content under sibling-app directories reachable via .. traversal. The endpoint requires no authentication.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
