Overview
CVE-2025-50972 describes a severe SQL Injection vulnerability in AbanteCart 1.4.2, a popular open-source e-commerce solution. This critical vulnerability is not only potent but also easily exploitable, allowing unauthenticated attackers to execute arbitrary SQL commands. If exploited, it can lead to severe consequences such as system compromise and data leakage. Given the broad use of AbanteCart in e-commerce platforms, this vulnerability poses a significant threat to businesses.

How the Exploit Works
The exploit works by manipulating the ‘tmpl_id’ parameter in an HTTP request to ‘index.php’ in the AbanteCart application. Attackers can use one of three demonstrated techniques to exploit the vulnerability: error-based injection using a crafted FLOOR-based payload, time-based blind injection via SLEEP(), or UNION-based injection to extract arbitrary data. Because the exploit doesn’t require authentication or user interaction, any attacker who can send HTTP requests to the application can potentially exploit the vulnerability.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited using the UNION-based injection technique:
GET /index.php?tmpl_id=1 UNION ALL SELECT NULL, NULL, NULL, CONCAT(user_name,':',password), NULL, NULL, NULL FROM users WHERE user_id=1-- HTTP/1.1
Host: target.example.comIn this example, the attacker appends a SQL UNION statement to the ‘tmpl_id’ parameter in an HTTP GET request. This UNION statement causes the application to return the username and password of the user with the ID 1.
Mitigation and Remediation
The best mitigation strategy for this vulnerability is to apply the vendor patch, which resolves the issue. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used as a temporary mitigation measure. These systems can be configured to detect and block the specific patterns of HTTP requests that exploit this vulnerability. It’s also recommended to review and update the security configurations of the affected systems regularly.
