Unknown · Advanced Poll · CVE-2006-2131
**Name of the Vulnerable Software and Affected Versions**
Advanced Poll version 2.0.4
**Description**
The issue allows remote attackers to spoof the source IP and bypass voting restrictions. This is because the `include/class poll.php` file in Advanced Poll uses the `HTTP X FORWARDED FOR` (X-Forwarded-For HTTP header) to identify the IP address of a client.
**Recommendations**
For Advanced Poll version 2.0.4, consider modifying the `include/class poll.php` file to use a more reliable method for identifying client IP addresses, such as checking the `REMOTE ADDR` variable, as a temporary workaround until a patch is available. Restrict access to voting functionality to minimize the risk of exploitation.
