CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Trend Micro Maximum Security, Internet Security and Antivirus+Securiuty 11.0 (Anti-Malware Software) and classified as critical. Affected by this issue is an unknown code block 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. CVE summarizes:

Code injection vulnerability in Trend Micro Maximum Security 11.0 (and earlier), Internet Security 11.0 (and earlier), and Antivirus+ Security 11.0 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Trend Micro 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.

The bug was discovered 03/22/2017. The weakness was presented 03/21/2017 (Website). The advisory is shared for download at cybellum.com. This vulnerability is handled as CVE-2017-5565 since 01/22/2017. The attack needs to be approached locally. The requirement for exploitation is a simple authentication.
