CVE-2025-2118: Quantico PRMV SQL Injection Vulnerability

CVE-2025-2118 Overview

A SQL injection vulnerability has been identified in Quantico Tecnologia PRMV version 6.48. The vulnerability exists in the /admin/login.php endpoint, where improper handling of the username parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, data modification, or complete database compromise.

Critical Impact

Remote attackers can exploit the SQL injection vulnerability in the login endpoint to bypass authentication, extract sensitive data, or manipulate database contents without requiring any prior authentication or user interaction.

Technical Details for CVE-2025-2118

Vulnerability Analysis

This vulnerability represents a classic SQL Injection flaw (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) in a web application login mechanism. The /admin/login.php endpoint fails to properly sanitize or parameterize the username input field before incorporating it into SQL queries. This allows an attacker to craft malicious input that alters the intended SQL query structure.

When a user submits login credentials, the application constructs a database query using the provided username value directly. Without proper input validation or the use of prepared statements, special SQL characters and commands within the username field are interpreted as part of the query itself rather than as literal data.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries in the login authentication mechanism. The application directly concatenates user-supplied input into SQL queries, allowing attackers to inject arbitrary SQL commands. This represents a failure to follow secure coding practices for database interactions.

Attack Vector

The vulnerability can be exploited remotely over the network without requiring authentication. An attacker targets the login form at /admin/login.php and submits specially crafted SQL injection payloads in the username field. The attack requires no user interaction and can be performed using standard web requests.

The exploitation process involves sending HTTP POST requests to the login endpoint with malicious SQL syntax in the username parameter. Common techniques include using single quotes to break out of string context, union-based injection to extract data from other tables, or boolean-based blind injection to enumerate database contents character by character. For technical details on the specific exploitation method, refer to the GitHub CVE Repository and VulDB entry #299013.

Detection Methods for CVE-2025-2118

Indicators of Compromise

• Unusual login attempts to /admin/login.php containing SQL metacharacters such as single quotes, double dashes, or UNION SELECT statements
• Web server logs showing abnormal POST request patterns to the login endpoint with encoded or obfuscated payloads
• Database error messages in application logs indicating SQL syntax errors from the authentication module
• Unexpected database queries or data access patterns originating from the web application

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests to /admin/login.php
• Configure intrusion detection systems to alert on SQL injection attack signatures in network traffic
• Enable verbose logging on the web server and database to capture suspicious query patterns and authentication attempts
• Deploy application-level monitoring to detect anomalous authentication behavior or database query failures

Monitoring Recommendations

• Monitor web server access logs for requests to /admin/login.php containing suspicious characters or keywords commonly used in SQL injection attacks
• Set up alerts for repeated failed login attempts that may indicate automated exploitation attempts
• Review database audit logs for unusual query patterns or unauthorized data access attempts
• Implement real-time security monitoring with correlation rules for detecting multi-stage SQL injection attacks

How to Mitigate CVE-2025-2118

Immediate Actions Required

• Restrict access to the /admin/login.php endpoint using IP whitelisting or VPN requirements until a patch is applied
• Deploy a Web Application Firewall with SQL injection protection rules in front of the application
• Review and audit database permissions to limit the impact of potential SQL injection exploitation
• Enable detailed logging on the web server and database to detect any ongoing exploitation attempts

Patch Information

No official patch information has been published by Quantico Tecnologia at the time of this writing. Organizations using PRMV 6.48 should contact the vendor directly for security updates and remediation guidance. Monitor the VulDB entry and vendor communications for patch availability.

Workarounds

• Implement input validation on the application layer to reject usernames containing SQL metacharacters before processing
• Use a reverse proxy or WAF to filter and block requests containing SQL injection patterns
• Restrict network access to the administrative login portal using firewall rules or access control lists
• Consider disabling the vulnerable login endpoint and using alternative authentication mechanisms if available

# Example: Apache mod_rewrite rule to block common SQL injection patterns
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} (\%27)|(\')|(\-\-)|(\%23)|(#) [NC,OR]
RewriteCond %{QUERY_STRING} (union.*select) [NC,OR]
RewriteCond %{QUERY_STRING} (select.*from) [NC]
RewriteRule ^/admin/login\.php - [F,L]
