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

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. (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.

Solution :

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