Detailsinfo

A vulnerability was found in Sophos Anti-Virus (Anti-Malware Software) (unknown version). It has been declared as problematic. Affected by this vulnerability is an unknown code block of the component BOPS ASLR Handler. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was published 11/05/2012 by Tavis Ormandy (@taviso) with Google Security Team as sophailv2.pdf as confirmed document (Full-Disclosure). The advisory is shared at lock.cmpxchg8b.com. The public release has been coordinated with Sophos. As demonstrated in the initial paper, installing Sophos Antivirus exposes machines to considerable risk. If Sophos do not urgently improve their security posture, their continued deployment causes significant risk to global networks and infrastructure. The exploitation appears to be difficult. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/01/2018). MITRE ATT&CK project uses the attack technique T1068 for this issue. Due to its background and reception, this vulnerability has a historic impact.

A public exploit has been developed by Tavis Ormandy (@taviso) and been published immediately after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 42 days. During that time the estimated underground price was around $25k-$100k.

Applying a patch is able to eliminate this problem. A possible mitigation has been published even before and not after the disclosure of the vulnerability. In response to early access to the initial report, Sophos did allocate some resources to resolve the issues discussed, however they were cearly ill-equipped to handle the output of one co-operative, non-adversarial security researcher. A sophisticated state-sponsored or highly motivated attacker could devastate the entire Sophos user base with ease.

The vulnerability is also documented in the databases at Exploit-DB (22509), SecurityFocus (BID 56401†), OSVDB (87058†), Secunia (SA51156†) and SecurityTracker (ID 1027725†). Additional details are provided at nakedsecurity.sophos.com. Similar entries are available at VDB-6868, VDB-6866, VDB-6870 and VDB-6867. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
