Discussion

LXR Cross Referencer Multiple Cross Site Scripting Vulnerabilities

LXR Cross Referencer is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data.

An attacker may leverage these issues 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.

LXR Cross Referencer 0.9.5 and 0.9.6 are affected; other versions may also be vulnerable.
