Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE-2023-30860
Summary
WWBN AVideo is an open source video platform. In wwbn/avideo versions prior to 12.4, a normal user can make a Meeting Schedule where the user can invite another user to that Meeting, but it does not properly sanitize the malicious characters when creating a Meeting Room. This allows an 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.

It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
