Parallels H-Sphere 3.0.0 P9 and 3.1 P1 contains multiple cross-site scripting vulnerabilities in login.php in webshell4. An attacker can inject arbitrary web script or HTML via the err, errorcode, and login parameters, thus allowing theft of cookie-based authentication credentials and launch of other attacks.
