Pico Server (pServ) 3.2 and earlier improperly resolves equivalent URL path representations when handling access to CGI resources. A remote request using a crafted intermediate directory and parent-directory sequence can bypass normal CGI handling and cause the server to return CGI script source code rather than executing the script. The issue is classified as CWE-41, Improper Resolution of Path Equivalence.
