Request Tracker 4.2.x < 4.2.5 Email::Address:List Module String Handling DoS

medium Nessus Plugin ID 76939

Language:

Synopsis

The remote web server is running a Perl application that is affected by a denial of service vulnerability.

Description

According to its self-reported version number, the Best Practical Solutions Request Tracker (RT) running on the remote web server is version 4.2.x prior to 4.2.5. It is, therefore, potentially affected by a denial of service vulnerability due to an algorithmic complexity flaw in the Perl CPAN Email::Address:List module. A remote attacker, by submitting a crafted string without an address, can exploit this to cause a denial of service through exhaustion of CPU resources.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Request Tracker 4.2.5 or Email::Address::List 0.02.
