CVE-2023-30860

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.

In AVideo, a normal user can make a Meeting Schedule where the user can invite another user in that Meeting, but I found out that it did not properly sanitize the malicious characters when creating a Meeting Room. This leads the attacker to put malicious scripts.

Impact:

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 without user interaction.

Step to Reproduce:

1. As normal USER go to Meet -> Schedule

2. In "Meet topic" field put XSS payload

Example: "><img src=x onerror=alert('Pawned+by+Gonz')>

3. Then click Save

4. Now as ADMIN go to Meet -> Schedule -> Upcoming

5. Then the XSS payload that normal USER created will be executed
