Overview
The cybersecurity landscape is constantly evolving, with new vulnerabilities being discovered and exploited. One such vulnerability has been identified in Foxcms v1.25, marked as CVE-2025-46154. This cybersecurity threat involves a SQL time injection in the $_POST[‘dbname’] parameter of installdb.php. Such vulnerabilities can lead to serious consequences, potentially compromising the system or leading to data leakage. This vulnerability affects all users of Foxcms v1.25, a widely used content management system, and thus warrants immediate attention and action.

How the Exploit Works
The vulnerability lies in the $_POST[‘dbname’] parameter of installdb.php. An attacker can manipulate this parameter to inject SQL commands into the system. This is achieved by exploiting the time-based blind SQL Injection vulnerability, where the attacker can send SQL queries that will cause the database to wait (or sleep) for a specified amount of time before responding. This delay in response can be used by the attacker to infer information about the database structure and data.
Conceptual Example Code
This is a conceptual example of how the vulnerability might be exploited. In this example, an HTTP POST request is made to the vulnerable endpoint with a malicious payload in the ‘dbname’ parameter.
POST /installdb.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
dbname=foxcmsDB'; IF (SELECT * FROM information_schema.tables WHERE table_schema = 'foxcmsDB' AND table_name = 'users') SLEEP(5) -- -In the above payload, the ‘dbname’ parameter is exploited to execute a SQL statement that checks for the existence of a ‘users’ table in the ‘foxcmsDB’ database. If the table exists, the SQL query will delay the response by 5 seconds, thus confirming the existence of the table to the attacker.
Mitigation and Prevention
The immediate mitigation for this vulnerability is to apply the vendor’s patch as soon as it is available. In the interim, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation by detecting and blocking SQL injection attempts. Regularly updating all software and maintaining good cybersecurity practices, such as limiting unnecessary privileges, can also help prevent exploitation of this and other vulnerabilities.
