Fujitsu-Siemens ServerView Remote Command Execution
RedTeam Pentesting discovered a remote command execution in the Fujitsu- Siemens ServerView during a penetration test. The DBAsciiAccess CGI script is vulnerable to a remote command execution because of a parameter which is not properly sanitized. An attacker may run arbitrary commands on the server with the permissions of the webserver user.
Product: Fujitsu Siemens Computers ServerView
Affected Versions: < 4.50.09
Fixed Versions: 4.50.09
Vulnerability Type: Remote Command Execution
Vendor-Status: informed, fixed version released
"ServerView provides asset management tools for automated analysis and version maintenance. It also supports the tracking of system installation and status by collecting inventory data. Because they are stored centrally, archives can be readily compared to a master version to trace changes over time and highlight differences with the original setup."
(from the vendor's homepage)
ServerView has a Remote Command Execution in its Webinterface. The DBAsciiAccess CGI script provides a "ping" functionality. In the subparameter "Servername" of the parameter "Parameterlist" of this script, the IP address to be pinged is given. This IP address will be given as a parameter to the ping program without further sanitization. By adding a trailing semicolon after the IP, an attacker can add arbitrary shell commands which will be executed with the permissions of the webserver user.
Proof of Concept
The following URL was wrapped for better readability.
Servername--127.0.0.1;id;,, # vulnerable parameter SType--Server"
Block access to the ServerView web interface for all untrusted users.
Version 4.50.09 of the linux agent fixes the problem. It can be downloaded with the SW-ID: 1013988 under
Fujitsu-Siemens decided to make a silent fix, as the vulnerability is not mentioned in the comments of the patch. They told RedTeam Pentesting that it is fixed in this version, though.
The security risk is high. An attacker is able to execute arbitrary commands on the server with the permissions of the webserver user.
