Advisory Details:
High-Tech Bridge Security Research Lab discovered a high-risk SQL injection vulnerability in Osclass, a popular web-based software for building customized classifieds marketplace. The vulnerability can be exploited to gain access to potentially sensitive information in the application database and even to compromise the entire website. The vulnerability exists due to insufficient filtration of user-supplied input data passed via the "itemsPerPage" HTTP GET parameter to "/index.php" PHP script. A remote unauthenticated attacker can modify the original SQL query and execute arbitrary SQL commands in application's database. A simple PoC code below uses a time-based SQL injection technique to demonstrate existence of the vulnerability. The following HTTP request will make page rendering very slow, if MySQL server uses 5th version: http://[host]/index.php?page=user&action=pub_profile&id=1&itemsPerPage=1%20P ROCEDURE%20analyse%28%28select%20extractvalue%28rand%28%29, concat%280x3a, %28IF%28MID%28version%28%29, 1, 1%29%20LIKE%205, %20BENCHMARK%285000000, SHA1%281%29%29, 1%29%29%29%29%29, 1%29
