Description

Secunia Research has discovered a vulnerability in Trend Micro OfficeScan, which can be exploited by malicious people to bypass authentication.

The vulnerability is caused due to insufficient entropy in a random session token used to identify an authenticated manager using the web console. An attacker can impersonate a currently logged on manager by predicting the authentication token.

NOTE: This vulnerability can further be exploited to execute arbitrary code.
