The weakness was disclosed 05/26/2014 by Rack911 as TSR-2014-2004 / Case 96381 as confirmed advisory (Website). The advisory is shared for download at cpanel.net. The attack needs to be approached locally. A single authentication is required for exploitation. There are known technical details, but no exploit is available. The advisory points out:

The chownpublichtmls script is intended to correct the ownership on users’ public_html directories. This script used an obsolete version of the safe_recchmod() function that was vulnerable to a race condition attack. This could allow a local attacker change the ownership of arbitrary files.

Upgrading to version 11.40.1.14, 11.42.1.16 or 11.43.0.12 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
