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

High Nessus Plugin ID 87240


The remote caching server is affected by multiple vulnerabilities.


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. (VulnDB 128881)

- 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. (VulnDB 128882)

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


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