Title:	Squirrelmail: Another XSS vulnerability
Date:	06/15/2004
Bugs:	#52434
ID:	200406-08

Synopsis

Squirrelmail fails to properly sanitize user input, which could lead to a compromise of webmail accounts.

Background

SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP, and can optionally be installed with SQL support.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
mail-client/squirrelmail	<= 1.4.3_rc1-r1	>= 1.4.3	All supported architectures

Description

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.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All SquirrelMail users should upgrade to the latest stable version:

    # emerge sync
    
    # emerge -pv ">=mail-client/squirrelmail-1.4.3"
    # emerge ">=mail-client/squirrelmail-1.4.3"
