Secunia Research has discovered a vulnerability in certain Trend Micro products, which can be exploited by malicious people to bypass authentication.
The vulnerability is caused by insufficient entropy being used to create a random session token for identifying an authenticated manager using the web management console. The entropy in the session token comes solely from the system time when the real manager logs in with a granularity of one second. This can be exploited to impersonate a currently logged on manager by brute forcing the authentication token.
Successful exploitation further allows execution of arbitrary code via manipulation of the configuration.
The vendor has issued patches for Trend Micro OfficeScan 8.0 and Worry-Free Business Security 5.0.
Fixes for other affected versions should be available shortly.
Discovered by Dyon Balding, Secunia Research.
The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2008-2433 for the vulnerability.
