## Technical details

A command injection vulnerability exists in the campas CGI program bundled with NCSA web servers. The issue stems from improper sanitization of input in the query string, specifically failing to handle encoded carriage return characters (%0D). An unauthenticated remote attacker can exploit this by submitting a crafted URL to execute arbitrary system commands with the privileges of the web server process. This has been demonstrated to allow the reading of sensitive files such as the system password file.
