PHD Help Desk is prone to multiple cross-site scripting vulnerabilities because the application fails to sufficiently sanitize user-supplied data.
    
Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials; other attacks are also possible.
    
PHD Help Desk 1.43 is vulnerable; other versions may also be affected.
