bizdb1-search.cgi located

BizDB is a web database 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. see also :
