PROBLEM
FluRDoInG [[email protected]] [http://www.flurnet.org] says :
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.
