The Finger Server is a perl script for providing .plan-like functionality through a website. Due to insufficient input checking, it is possible for remote unauthenticated users to execute shell commands on the server which will run with the privileges of the webserver. A request like: http://target/finger.cgi?action=archives&cmd=specific&filename=99.10.28.15.23.username.|<shell command>| will cause the server to execute whatever command is specified.
