CVE-2025-10667: Emiloi Discussion Forum SQLi Vulnerability

CVE-2025-10667 Overview

A SQL injection vulnerability has been identified in itsourcecode Online Discussion Forum version 1.0. The vulnerability affects the /members/compose_msg.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This weakness enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive user data, modify database contents, or potentially gain unauthorized access to the underlying system through database-level privileges.

Technical Details for CVE-2025-10667

Vulnerability Analysis

This SQL injection vulnerability exists in the message composition functionality of the Online Discussion Forum application. The /members/compose_msg.php endpoint accepts an ID parameter that is directly incorporated into database queries without proper sanitization or parameterization. This classic injection flaw allows attackers to escape the intended query structure and execute arbitrary SQL commands against the backend database.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating that user-supplied input is not properly neutralized before being used in database operations. The attack can be executed remotely without authentication, making it particularly dangerous for publicly accessible forum installations.

Root Cause

The root cause of this vulnerability is the direct concatenation of user-supplied input (the ID parameter) into SQL queries without proper validation, sanitization, or the use of prepared statements with parameterized queries. The application fails to treat user input as untrusted data, allowing special SQL characters and commands to be interpreted by the database engine rather than being treated as literal string values.

Attack Vector

The attack vector is network-based, allowing remote exploitation without requiring user interaction or prior authentication. An attacker can craft malicious HTTP requests to the /members/compose_msg.php endpoint with specially crafted ID parameter values containing SQL injection payloads. These payloads can include UNION-based queries for data extraction, boolean-based blind injection for inference attacks, or time-based blind injection techniques.

The vulnerability mechanism involves improper handling of the ID parameter in the message composition functionality. When a user request reaches /members/compose_msg.php, the application extracts the ID value and incorporates it directly into a database query. An attacker can manipulate this parameter to include SQL syntax such as single quotes, UNION statements, or conditional expressions that alter the query's logic.

Detection Methods for CVE-2025-10667

Indicators of Compromise

• Unusual database query patterns in application logs, particularly those containing SQL keywords like UNION, SELECT, OR 1=1, or comment sequences (--, /**/)
• Unexpected error messages or database exceptions logged from the /members/compose_msg.php endpoint
• Abnormal access patterns to the compose message functionality from single IP addresses or automated scanning tools
• Evidence of data exfiltration or unauthorized database modifications in audit logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the ID parameter of requests to /members/compose_msg.php
• Implement application-level logging to capture all requests with suspicious characters in URL parameters, including single quotes, semicolons, and SQL keywords
• Enable database query logging and monitor for anomalous query structures or execution times indicative of blind SQL injection attempts
• Configure intrusion detection systems (IDS) to alert on SQL injection signature patterns targeting PHP applications

Monitoring Recommendations

• Monitor web server access logs for requests to /members/compose_msg.php containing encoded or unencoded SQL special characters
• Set up alerts for database errors or exceptions that may indicate failed injection attempts
• Track database connection patterns and query execution times for anomalies that could suggest successful exploitation

How to Mitigate CVE-2025-10667

Immediate Actions Required

• Remove or restrict public access to the Online Discussion Forum application until a patch is available
• Implement Web Application Firewall rules to filter SQL injection payloads targeting the ID parameter
• Review database user permissions and ensure the application uses least-privilege database accounts
• Enable detailed logging for the affected endpoint to monitor for exploitation attempts

Patch Information

As of the last NVD update on September 20, 2025, no official vendor patch has been released for this vulnerability. Organizations using the affected itsourcecode Online Discussion Forum 1.0 should monitor the IT Source Code Resource for security updates. Given that the exploit has been publicly disclosed, applying compensating controls is critical until an official fix is available.

Workarounds

• Implement input validation on the ID parameter to accept only numeric values, rejecting any requests containing non-numeric characters
• Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
• Modify the application code to use prepared statements with parameterized queries for all database interactions involving user input
• Consider disabling or restricting access to the /members/compose_msg.php functionality if message composition is not critical to operations
