Description
Multiple Vulnerabilities found in Advanced Poll (http://proxy2.de/scripts.php) script.
1. SQL Injection.
Vulnerable script: include/class_poll.php
UserAgent value from header of HTTP-query is not properly sanitized before being used in SQL query. This can be used to make some SQL queries by injecting arbitrary SQL code.
Condition: magic_quotes_gpc = off
2. Unauthorized Data Modification.
Vulnerable Script: include/class_poll.php
This attack would lead the coordinates to be spoofed and taken over by illegal Proxies. This is done, by checking if HTTP_X_FORWARDED_FOR exists and using this IP from HTTP_X_FORWARDED_FOR to identify unique voted person.
The attacker can send fake HTTP_X_FORWARDED_FOR values in http-headers as many as the attacker wants with different IP in HTTP_X_FORWARDED_FOR.
PoC/Exploit
