A vulnerability classified as critical has been found in Sony Playstation 3 Firmware 4.31 (Game Console). This affects an unknown code block of the file PARAM.SFO of the component Save Game Handler. The manipulation as part of a Splitted Char leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability.

The weakness was released 05/13/2013 by Benjamin Kunz Mejri (bkm) with Vulnerability Laboratory Research Team as WLB-2013050161 as not defined advisory (Website). It is possible to read the advisory at cxsecurity.com. The public release was coordinated with Sony. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details and a public exploit are known. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/20/2018). The attack technique deployed by this issue is T1068 according to MITRE ATT&CK. Due to its background and reception, this vulnerability has a historic impact.

A public exploit has been developed by Benjamin Kunz Mejri (bkm) in PS3 Save Game and been published immediately after the advisory. The exploit is shared for download at cxsecurity.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 164 days. During that time the estimated underground price was around $25k-$100k. Successful exploitation of the vulnerability can result in persistent but local system command executions, psn session hijacking, persistent phishing attacks, external redirect out of the vulnerable module, stable persistent save game preview listing context manipulation.

A possible mitigation has been published even before and not after the disclosure of the vulnerability.
