CVE-2026-2117: Society Management System SQLi Vulnerability

CVE-2026-2117 Overview

A SQL injection vulnerability has been identified in itsourcecode Society Management System version 1.0. The vulnerability exists in the /admin/edit_activity.php file, where the activity_id parameter is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to manipulate database queries by injecting malicious SQL code through the vulnerable parameter.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to potentially access, modify, or delete sensitive data stored in the application's database, bypass authentication mechanisms, or escalate privileges within the system.

Technical Details for CVE-2026-2117

Vulnerability Analysis

This SQL injection vulnerability occurs in the administrative functionality of Society Management System, specifically within the activity editing feature. The application fails to implement proper input validation and parameterized queries when processing the activity_id parameter in /admin/edit_activity.php. This weakness allows attackers to inject arbitrary SQL commands that are executed by the database server with the privileges of the web application's database user.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection vulnerabilities where user-controllable input is not properly neutralized before being processed by an interpreter.

Root Cause

The root cause of this vulnerability is the direct concatenation or interpolation of user-supplied input (activity_id parameter) into SQL query strings without proper sanitization, escaping, or the use of parameterized queries (prepared statements). The application trusts user input and incorporates it directly into database operations, creating an injection point that attackers can exploit.

Attack Vector

The attack can be initiated remotely over the network without requiring authentication or user interaction. An attacker can craft malicious HTTP requests targeting the /admin/edit_activity.php endpoint with specially crafted activity_id parameter values containing SQL injection payloads. Successful exploitation could allow the attacker to:

• Extract sensitive data from the database including user credentials and personal information
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially execute operating system commands depending on database configuration

The exploit has been publicly disclosed and could be readily used by attackers. Technical details and proof-of-concept information can be found in the GitHub CVE Issue Discussion.

Detection Methods for CVE-2026-2117

Indicators of Compromise

• Unusual or malformed values in the activity_id parameter containing SQL syntax such as single quotes, UNION statements, or comment characters
• Database error messages appearing in HTTP responses indicating SQL syntax errors
• Unexpected database queries in logs containing SQL injection patterns
• Anomalous database activity such as bulk data extraction or unauthorized data modifications

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in HTTP request parameters
• Monitor web server access logs for requests to /admin/edit_activity.php containing suspicious characters or encoded SQL keywords
• Enable database query logging and monitor for unusual query patterns or syntax errors
• Deploy application security monitoring to detect injection attempts in real-time

Monitoring Recommendations

• Configure alerting for multiple failed database queries originating from the same source IP
• Monitor for data exfiltration patterns indicating successful SQL injection exploitation
• Implement intrusion detection rules specifically targeting SQL injection attack signatures
• Review authentication logs for signs of authentication bypass attempts

How to Mitigate CVE-2026-2117

Immediate Actions Required

• Restrict access to the /admin/edit_activity.php file through web server configuration or firewall rules until a patch is available
• Implement input validation to allow only numeric values for the activity_id parameter
• Consider taking the affected administrative functionality offline if the system contains sensitive data
• Review database logs for evidence of prior exploitation and assess potential data compromise

Patch Information

As of the last update on 2026-02-10, no official vendor patch has been released for this vulnerability. Users should monitor the IT Source Code Blog for security updates. Additional vulnerability details are available through VulDB #344692.

Workarounds

• Implement a Web Application Firewall (WAF) with SQL injection detection rules in front of the application
• Restrict network access to the administrative interface to trusted IP addresses only
• Add server-side input validation to ensure activity_id accepts only integer values
• Consider implementing prepared statements/parameterized queries at the application code level if source code access is available

# Example Apache configuration to restrict access to admin directory
<Directory "/var/www/html/admin">
    # Restrict to internal network only
    Require ip 10.0.0.0/8 192.168.0.0/16
    # Deny all other access
    Require all denied
</Directory>
