SquirrelMail MIME header cross-site scripting
| squirrelmail-mimeheader-xss (30695) |  Medium Risk |
Description:
SquirrelMail is vulnerable to cross-site scripting, caused by improper validation of email attachments when using Internet Explorer. A remote attacker could exploit this vulnerability using a specially-crafted MIME header to execute script in a victim's Web browser within the security context of the hosting Web site, once the message is opened. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
