## What is CVE-2023-30860?

CVE-2023-30860 is a high-severity cross-site scripting vulnerability in Wwbn Avideo, published on 8 May 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

WWBN AVideo is an open source video platform. In AVideo prior to version 12.4, a normal user can make a Meeting Schedule where the user can invite another user in that Meeting, but it does not properly sanitize the malicious characters when creating a Meeting Room. This allows attacker to insert malicious scripts. Since any USER including the ADMIN can see the meeting room that was created by the attacker this can lead to cookie hijacking and takeover of any accounts. Version 12.4 contains a patch for this issue.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
