CVE-2015-10133: subscribe to comments vulnerability

What is known

The Subscribe to Comments for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 2.1.2 via the Path to header value. This allows authenticated attackers, with administrative privileges and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. This same function can also be used to execute arbitrary PHP code.

Business impact

Successful exploitation of CVE-2015-10133, a high vulnerability (CVSS 7.2) affecting subscribe to comments, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether subscribe to comments is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
