Description
This security bulletin contains information about 1 security vulnerability.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2015-3185)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
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
Install update from vendor's website.
