How the Exploit Works
The vulnerability resides in the CUtils.checkSQLInjection() function in the Advantech iView software, which fails to properly sanitize user-supplied input. An attacker can exploit this weakness by injecting malicious SQL commands into the system via this function, potentially leading to unauthorized access, data disclosure, or triggering a denial-of-service condition.
Conceptual Example Code
Here is a
conceptual
example of how the vulnerability might be exploited. This could be a sample HTTP request with an SQL injection payload.
POST /iview/checkSQLInjection HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=' OR '1'='1';--&password=In the above example, the SQL injection payload `’ OR ‘1’=’1′;–` forces the SQL query to always return `true`, potentially bypassing authentication mechanisms and granting unauthorized access.
Recommended Mitigations
To address this vulnerability, users are advised to apply the vendor-provided patch as soon as possible. In the meantime, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. Regular updates and strong security practices can also help in preventing these types of vulnerabilities.
