JaxUltraBB Cross Site Scripting and Local File Include Vulnerabilities

JaxUltraBB is prone to a local file-include vulnerability and a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input.

An attacker may leverage the cross-site scripting issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

Exploiting the local file-include issues allows remote attackers to view local files within the context of the webserver process.

JaxUltraBB 2.0 is vulnerable; prior versions may also be affected.
