SquirrelMail < 1.4.21 Multiple Vulnerabilities

Medium Nessus Network Monitor Plugin ID 5629


The remote web server if vulnerable to a denial-of-service attack.


The remote host is running SquirrelMail, a web-based email client.

Versions of SquirrelMail earlier than 1.4.21 are potentially affected by a denial-of-service vulnerability. By submitting a random login with 8-bit characters in the password, it is possible to cause SquirrelMail to create a preferences file even if the login is not valid. An attacker, exploiting this flaw, could create enough files to cause the server to run out of disk space.


Upgrade to SquirrelMail 1.4.21 or later.
