Brian Stanback bsguest.cgi Remote Command Execution Vulnerability
An input validation vulnerability exists in Brian Stanback's bsguest.cgi, a script designed to coordinate guestbook submissions from website visitors. The script fails to properly filter ';' characters from the user-supplied email address collected by the script. As a result, maliciously-formed values for this field can cause the the script to run arbitrary shell commands with the privilege level of the web server. |
