How the Exploit Works

The vulnerability arises from an unknown part of the file /view-pass-detail.php. The improper handling of the ‘viewid’ argument in this file allows the attacker to manipulate SQL queries in the back-end database. This is achieved by injecting malicious SQL statements via the ‘viewid’ parameter. This could result in unauthorized access to the database, system compromise, or data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This example represents a malicious HTTP request:

GET /view-pass-detail.php?viewid=' OR '1'='1';-- HTTP/1.1
Host: target.example.com

In this example, the ‘viewid’ parameter is manipulated with a classic SQL injection payload `’ OR ‘1’=’1′;–`. This payload would return true for every row in the table, potentially revealing all records.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block SQL injection attempts. Additionally, it is advisable to implement secure coding practices to avoid such vulnerabilities in the future.
