Trend Micro ServerProtect Web Interface Authorization Bypass Vulnerability



Trend ServerProtect is an Anti-virus application designed to run on file servers to catch viruses before they make it to network users. More information can be found on the vendors site at:


TrendMicro's ServerProtect product uses a web interface which runs on port TCP 14942 to configure the product. This interface is protected with a user configurable password. Upon successful login, a cookie is set with the name 'splx_2376_info' and a valid session id as its value.

The ServerProtect web application suffers from a design error vulnerability in its authorization checking routines. Attackers can gain full access to the web application by requesting any internal page while supplying their own 'splx_2376_info' cookie with an arbitrary value.


Exploitation of this vulnerability allows a remote attacker to edit and disable Anti-Virus features on the server machine.

Cookie values can be easily edited using raw HTTP requests or tools such as intercept proxies and browser plug-ins. By not checking for a valid session id and only looking for the cookie name, any value can grant an attacker full access to the web application.


iDefense has confirmed this vulnerability in Trend ServerProtect v1.3 for Linux. This vulnerability is not present in the Windows based versions of Server protect.


iDefense recommends limiting network access to the ServerProtect web interface to trusted clients.
