Barracuda CudaTel 'bbx_backup_site_host' Parameter Multiple Cross Site Scripting Vulnerabilities

Barracuda CudaTel Communication Server is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied input.

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 can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Barracuda CudaTel Communication Server 2.6.02.040 is vulnerable; other versions may also be affected.
