Along with this I was able in some sites to determine that you can overwrite the databse contents and also if you look in the source you se there password the server name and the dbuser htis is a problem because most likely the site cocould be taken over
Due to the fact the admin doesnt usually change passwords on the same box
 
 
Vulnerable software is videodb
 
This is an information disclosure vulnerability it appears most sites running this are vulnerable and have the same database structure im not sure if this is an old version or if it is
Completely vulnerable im downloading the new version now from source

Addslashes is the problem I assume it cocould BE MUCH WORSE IF HE MADE THIS MISTAKE I URGE YOU ALL TOO LOOK INTO THE CODE
 
 
The problem here is the fact he is using addslashes that can be bypassed with a valid multi byte ending in 0x5c describd in chris Shiflett's article
 
If I must say this cocould be either good or bad thing is it just throws an error the injection is possible on all of these
Nnow what are we to do this cocould be huge or small depending on if it is used widely or just small based but this is the new code from sourceforge
 
 
I believe this to B the script that caused the issue most of the sites including the makers demo use borrow few others changed
