SquirrelMail multiple PHP script cross-site scripting

squirrelmail-php-xss (10145) The risk level is classified as MediumMedium Risk


SquirrelMail is vulnerable to cross-site scripting. A remote attacker could embed malicious script within a URL request as a parameter to the addressbook, options, search, or help PHP script, which would be executed in the victim's Web browser within the security context of the hosting site, once the link is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials and possibly gain unauthorized access to the victim's Web mail account. This vulnerability could also be exploited by inserting email addresses containing script embedded within HTML tags directly within the victim's address book.
