Detailsinfo

A vulnerability was found in BitDefender Total Security, Internet Security and Antivirus Plus up to 12.0 (Anti-Malware Software). It has been rated as critical. This issue affects an unknown functionality of the component Self-Protection. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Code injection vulnerability in Bitdefender Total Security 12.0 (and earlier), Internet Security 12.0 (and earlier), and Antivirus Plus 12.0 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Bitdefender process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider DLL under Image File Execution Options in the registry; (2) the self-protection mechanism is intended to block all local processes (regardless of privileges) from modifying Image File Execution Options for these products; and (3) this mechanism can be bypassed by an attacker who temporarily renames Image File Execution Options during the attack.
