Overview

CVE-2015-3185 is a medium-severity vulnerability affecting canonical ubuntu_linux. It was published on July 20, 2015 and has a CVSS 2.0 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The ap_some_auth_required function in server/request.c in the Apache HTTP Server 2.4.x before 2.4.14 does not consider that a Require directive may be associated with an authorization setting rather than an authentication setting, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging the presence of a module that relies on the 2.2 API behavior.

Remediation

Check the references section for vendor advisories and patches from canonical. Update ubuntu_linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
