HuangDou UTCMS | V9
How the Exploit Works
The vulnerability exists in the RunSql function of the mysql.php file within HuangDou UTCMS V9. Specifically, the function does not sanitize the ‘sql’ argument properly, allowing an attacker to inject malicious SQL commands. These commands can manipulate, delete, or extract sensitive data from the underlying database, leading to the potential compromise of the system or data leakage.
Conceptual Example Code
An attacker exploiting this vulnerability might use a specially crafted HTTP POST request like the following:
POST /app/modules/ut-data/admin/mysql.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
sql=DROP TABLE users;
In this example, if the targeted system is vulnerable and fails to sanitize the ‘sql’ parameter, the SQL command ‘DROP TABLE users;’ will be executed, leading to the deletion of the ‘users’ table from the database.
Mitigation
To mitigate this vulnerability, affected systems should apply the latest security patches provided by the vendor as soon as possible. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block SQL injection attacks can serve as a temporary mitigation strategy. Regular review and update of security policies, plus ongoing staff training on security awareness, are also crucial to decrease the vulnerability of systems to such attacks.
