A vulnerability classified as problematic was found in cPanel 11.38.2/11.40.1/11.42.0 (Hosting Control Software). Affected by this vulnerability is an unknown part of the component trackupload. The manipulation as part of a HTTP Request leads to a symlink vulnerability. The CWE definition for the vulnerability is CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. As an impact it is known to affect integrity, and availability.

The weakness was shared 03/31/2014 by Rack911 with cPanel Security Team as TSR 2014-0003 as confirmed advisory (Website). It is possible to read the advisory at cpanel.net. The vendor cooperated in the coordination of the public release. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. Technical details are unknown but an exploit is available. The advisory points out:

The trackupload functionality in cPanel & WHM’s default POST parameter and QUERY_STRING processor module allows a log file to be written and queried while a file upload is occurring. In some contexts, an authenticated attacker could make cpsrvd create the trackupload log file inside the user’s home directory while running with the effective UID of root. By combining this with a symlinked trackupload log file target, any file on the system could be overwritten.

It is declared as highly functional.

Upgrading to version 11.42.0.23, 11.40.1.13 or 11.38.2.23 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at X-Force (92245). The entries 12792, 12793, 12794 and 12795 are related to this item.
