- Summary
- WWBN AVideo: Unauthenticated CRLF/ICS Injection in Scheduler downloadICS.php Allows Calendar Event Spoofing
- Details
-
WWBN AVideo is an open source video platform. In versions up to and including 29.0, the unauthenticated plugin/Scheduler/downloadICS.php endpoint passes attacker-controlled title, description, and joinURL parameters into Scheduler::downloadICS(), which builds an ICS calendar file via the ICS helper class. ICS::escape_string() (objects/ICS.php:167-169) only escapes , and ; and does NOT neutralize CR/LF, so attacker CRLF bytes inside a property value break out and inject arbitrary ICS lines — including END:VEVENT / BEGIN:VEVENT pairs that add entire attacker-controlled calendar events. Because the malicious .ics file is served from the victim's trusted AVideo origin, this enables high-credibility calendar phishing: forged meetings with attacker-chosen SUMMARY, URL, LOCATION, and DESCRIPTION landing in the victim's calendar after import. Commit 764db592f99e545aa86bb9a4ad664ffd14c38ba5 contains an updated fix.
