La vulnerabilidad de inyección de comandos proxy en Trend Micro OfficeScan 11 y XG (12) permite que atacantes remotos puedan ejecutar código arbitrario en instalaciones vulnerables. Este error específico se puede explotar parseando el parámetro tr en Proxy.php. Anteriormente ZDI-CAN-4543.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Trend Micro OfficeScan. Authentication is required to exploit this vulnerability.
The specific flaw exists within the Web Console, which listens on TCP port 4343 by default. When parsing the tr parameter in Proxy.php, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current service.
