How the Exploit Works
The SQL injection vulnerability in SEMCMS v4.8 is due to insufficient input validation of the ‘languageID’ parameter in /web_inc.php. An attacker could exploit this vulnerability by sending specially crafted data into the ‘languageID’ parameter. As a result, the attacker can manipulate SQL queries, potentially gaining unauthorized access to sensitive data or even gaining control over the system.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited. An attacker could send a malicious SQL statement through the ‘languageID’ parameter, which could then potentially manipulate the database or disclose sensitive data.
GET /web_inc.php?languageID=1' or '1'='1 HTTP/1.1
Host: vulnerable-website.comIn this example, the `1′ or ‘1’=’1` is a classic SQL injection payload that will always evaluate to true, potentially revealing all entries in a database table if not properly handled.
Mitigation Guidance
Users are strongly advised to apply the latest patches provided by the vendor. If the patch is unavailable, use Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Furthermore, it’s recommended to review and update the system’s input validation techniques to prevent similar vulnerabilities in the future.
