Technical details
The Perl implementation of the finger daemon (fingerd) contains a vulnerability that allows for remote command execution. The flaw likely stems from improper sanitization of input passed to the finger service, which is then executed by the Perl interpreter. A remote, unauthenticated attacker can exploit this by sending a specially crafted request to the finger port (typically TCP 79). Successful exploitation grants the attacker the ability to run arbitrary shell commands with the privileges of the fingerd process.
