A vulnerability was found in Joomla CMS (Content Management System) (version unknown) and classified as critical. Affected by this issue is an unknown function of the component Session ID Handler. The manipulation of the argument session_ids with an unknown input leads to a missing encryption vulnerability. Using CWE to declare the problem leads to CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. Impacted is confidentiality, integrity, and availability.

The weakness was disclosed 09/20/2016 by Blazej Adamczyk as not defined mailinglist post (Full-Disclosure). The advisory is available at seclists.org. The exploitation is known to be easy. The attack may be launched remotely. The successful exploitation requires a simple authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 04/21/2019). This vulnerability is assigned to T1600 by the MITRE ATT&CK project. The advisory points out:

The session_ids for all joomla users are stored in plaintext in the “prefix_session” table. This allows the attacker to exploit an SQLi to retrieve the session id and access Joomla! backend with user (victim) privileges. The session_id cookie value should not be stored in the database. A cryptographic hash function should be used instead and the real cookie should be known only to the user. On each request Joomla should compare the hash of the cookie with the value stored in db.

The mailinglist post contains the following remark:

The aim of this diclosure is to attract the attention of Joomla! community/developers and start a dicussion for a proper fix.
