- The target is running at least one instance of SquirrelMail whose
- version number suggests it is vulnerable to one or more cross-site
- scripting vulnerabilities :
-
- - Insufficient escaping of integer variables in webmail.php allows a
- remote attacker to include HTML / script into a SquirrelMail webpage
- (affects 1.4.0-RC1 - 1.4.4-RC1).
-
- - Insufficient checking of incoming URL vars in webmail.php allows an
- attacker to include arbitrary remote web pages in the SquirrelMail
- frameset (affects 1.4.0-RC1 - 1.4.4-RC1).
-
- - A recent change in prefs.php allows an attacker to provide a
- specially crafted URL that could include local code into the
- SquirrelMail code if and only if PHP's register_globals setting is
- enabled (affects 1.4.3-RC1 - 1.4.4-RC1).
-
- ***** Nessus has determined the vulnerability exists on the target
- ***** simply by looking at the version number of Squirrelmail
- ***** installed there.
-
- Solution : Upgrade to SquirrelMail 1.4.4 or later.
