Squirrelmail fails to properly sanitize user input, which could lead to a compromise of webmail accounts.
SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP, and can optionally be installed with SQL support.
A new cross-site scripting (XSS) vulnerability in Squirrelmail-1.4.3_rc1 has been discovered. In functions/mime.php Squirrelmail fails to properly sanitize user input.
By enticing a user to read a specially crafted e-mail, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's webmail account, cookie theft, etc.
There is no known workaround at this time.
All SquirrelMail users should upgrade to the latest stable version:
