Apache Traffic Server 5.3.x < 5.3.1 'url_sig' Plugin Multiple Vulnerabilities

critical Nessus Plugin ID 87240

Language:

Synopsis

The remote caching server is affected by multiple vulnerabilities.

Description

According to its banner, the version of Apache Traffic Server running on the remote host is 5.3.x prior to 5.3.1. It is, therefore, affected by multiple vulnerabilities related to the 'url_sig' plugin :

- An out-of-bounds access error exists that is triggered when handling a specially crafted HTTP request. An unauthenticated, remote attacker can exploit this to crash the server.

- A security bypass vulnerability exists due to a flaw that is triggered when handling empty secret key URLs.
An unauthenticated, remote attacker can exploit this to bypass validation mechanisms, thereby gaining access to protected assets.

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

Solution

Upgrade to Apache Traffic Server version 5.3.1 or later.
Alternatively, disable the 'url_sig' plugin.
