CVE-2025-40628: DomainsPRO SQL Injection Vulnerability

CVE-2025-40628 Overview

CVE-2025-40628 is a critical SQL injection vulnerability affecting DomainsPRO version 1.2. This vulnerability allows an unauthenticated attacker to perform arbitrary SQL operations against the underlying database through the d parameter in the /article.php endpoint. Successful exploitation enables attackers to retrieve, create, update, and delete database contents, potentially compromising the entire application and its data.

Critical Impact

Unauthenticated attackers can fully compromise database integrity and confidentiality through SQL injection, enabling data theft, modification, or complete destruction of database contents.

Affected Products

• DomainsPRO version 1.2

Technical Details for CVE-2025-40628

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists in the DomainsPRO web application's article handling functionality. The /article.php endpoint fails to properly sanitize user-supplied input passed through the d parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that execute with the privileges of the database user configured for the application.

The vulnerability is particularly dangerous as it requires no authentication and can be exploited remotely over the network with low complexity. An attacker can leverage this flaw to extract sensitive information from the database, modify existing records, insert malicious data, or delete critical database tables entirely.

Root Cause

The root cause of CVE-2025-40628 is improper input validation and the likely use of dynamic SQL query construction without parameterized queries or prepared statements. When the /article.php script receives a value for the d parameter, it appears to concatenate this input directly into SQL statements without proper sanitization, escaping, or the use of parameterized queries. This allows attacker-controlled input to break out of the intended SQL context and execute arbitrary database commands.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /article.php endpoint with SQL injection payloads in the d parameter. The vulnerability allows for various SQL injection techniques including:

• Union-based injection to extract data from other tables
• Error-based injection to enumerate database structure
• Time-based blind injection for data exfiltration
• Stacked queries (if supported) for data modification or deletion

The vulnerability can be exploited by sending crafted GET or POST requests containing SQL injection payloads. Attackers can manipulate the d parameter to terminate the legitimate query and append malicious SQL statements. For detailed technical information, refer to the INCIBE Security Notice.

Detection Methods for CVE-2025-40628

Indicators of Compromise

• Unusual or malformed requests to /article.php containing SQL syntax in the d parameter
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or operations logged by database monitoring tools
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns targeting the /article.php endpoint
• Monitor HTTP access logs for requests containing suspicious characters in the d parameter such as single quotes, double dashes, UNION keywords, or encoded SQL syntax
• Enable database query logging and alert on anomalous query patterns or syntax errors
• Deploy intrusion detection systems with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Configure real-time alerting for requests to /article.php containing SQL injection indicators
• Monitor database audit logs for unauthorized SELECT, INSERT, UPDATE, or DELETE operations
• Track failed authentication attempts and unusual access patterns to the database server
• Review web server logs regularly for reconnaissance activity targeting the vulnerable endpoint

How to Mitigate CVE-2025-40628

Immediate Actions Required

• Restrict access to the /article.php endpoint using firewall rules or web server configuration until a patch is available
• Implement WAF rules to block requests containing SQL injection payloads in the d parameter
• Review and audit database permissions to ensure the application uses least-privilege database accounts
• Back up all database contents immediately to enable recovery in case of exploitation

Patch Information

No vendor patch information is currently available. Organizations using DomainsPRO 1.2 should monitor the INCIBE Security Notice for updates and contact the vendor directly for remediation guidance.

Workarounds

• Block or filter all requests to /article.php at the network or web server level
• If possible, disable the vulnerable functionality until a patch is released
• Implement strict input validation at the application layer to reject requests containing SQL metacharacters
• Consider deploying the application behind a reverse proxy with robust SQL injection filtering capabilities

# Example Apache configuration to block access to vulnerable endpoint
<Location "/article.php">
    Order deny,allow
    Deny from all
    # Allow only from trusted internal IPs if needed
    # Allow from 192.168.1.0/24
</Location>
