Overview
PGPMail.pl does not adequately filter user input, allowing arbitrary command execution.
Description
PGPMail.pl is an adaptation of the FormMail.pl CGI script, enhanced to use PGP encryption. PGPMail.pl does not adequately filter the "recipient" and "pgpuserid" CGI variables before passing them to piped Perl open() function calls, inevoking shells. As a result, attackers may execute arbitrary commands on the server with privileges of the web server process. |
Impact
Remote attackers can execute arbitrary commands on the server with privileges of the web server process. |
Solution
The CERT/CC is currently unaware of a practical solution to this problem. |
