CVE-2026-2115: Society Management System SQLi Vulnerability

CVE-2026-2115 Overview

A SQL injection vulnerability has been identified in itsourcecode Society Management System version 1.0. The vulnerability exists in the file /admin/delete_expenses.php where improper handling of the expenses_id parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially allowing unauthorized access to the database, data manipulation, or information disclosure.

Critical Impact

This SQL injection vulnerability enables remote attackers to execute arbitrary SQL commands against the backend database, potentially compromising data confidentiality, integrity, and availability. The exploit has been publicly disclosed and may be actively used.

Technical Details for CVE-2026-2115

Vulnerability Analysis

This vulnerability is classified as SQL Injection (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component). The flaw resides in the administrative functionality of the Society Management System, specifically within the expense deletion feature. When processing requests to delete expense records, the application fails to properly sanitize or parameterize the expenses_id input before incorporating it into SQL queries.

The vulnerability is network-accessible and requires no authentication or user interaction to exploit, making it particularly dangerous for internet-facing deployments. Successful exploitation could allow attackers to read sensitive data from the database, modify or delete records, or potentially escalate to broader system compromise depending on database configuration and privileges.

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries or prepared statements when handling the expenses_id parameter. The application directly concatenates user-supplied input into SQL queries without proper sanitization, allowing attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack is conducted remotely over the network by sending specially crafted HTTP requests to the /admin/delete_expenses.php endpoint. An attacker can manipulate the expenses_id parameter to include SQL metacharacters and malicious SQL statements. Since no authentication appears to be required for this endpoint, or the authentication can be bypassed, attackers can directly target the vulnerable parameter.

The vulnerability allows for various SQL injection techniques including:

• Union-based injection to extract data from other tables
• Boolean-based blind injection to infer database contents
• Time-based blind injection for data exfiltration
• Stacked queries (depending on database configuration) for data modification or deletion

Technical details and proof-of-concept information can be found in the GitHub Issue Discussion and VulDB #344690.

Detection Methods for CVE-2026-2115

Indicators of Compromise

• Unusual or malformed requests to /admin/delete_expenses.php containing SQL metacharacters such as single quotes, double dashes, or UNION keywords in the expenses_id parameter
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or data access patterns, particularly SELECT statements accessing multiple tables
• Web server access logs showing repeated requests to the vulnerable endpoint with varying parameter values

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the expenses_id parameter
• Deploy database activity monitoring to identify anomalous queries originating from the web application
• Configure intrusion detection systems (IDS) with signatures for common SQL injection payloads
• Review web server access logs for requests containing SQL metacharacters in query parameters

Monitoring Recommendations

• Enable detailed logging for the Society Management System application, particularly for administrative functions
• Monitor database query logs for unexpected or unauthorized data access patterns
• Set up alerts for multiple failed or malformed requests to administrative endpoints
• Implement real-time security monitoring for the /admin/ directory and related PHP files

How to Mitigate CVE-2026-2115

Immediate Actions Required

• Restrict network access to the /admin/delete_expenses.php endpoint using firewall rules or .htaccess configurations
• Implement IP-based access controls to limit administrative interface access to trusted networks only
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Consider taking the vulnerable application offline until a patch is available or the code can be remediated

Patch Information

No official vendor patch has been identified at this time. The affected software is distributed through IT Source Code. Organizations using this software should contact the vendor or development community for updates. If source code access is available, implement parameterized queries or prepared statements to address the SQL injection vulnerability directly.

For additional vulnerability details and community discussion, refer to the VulDB CTI ID #344690 and VulDB Submission ID #746797.

Workarounds

• Apply input validation to the expenses_id parameter by ensuring it only accepts numeric values
• Implement prepared statements or parameterized queries in the delete_expenses.php file
• Add server-level request filtering to block requests containing SQL injection patterns
• Enforce strong authentication and authorization checks for all administrative endpoints
• Consider migrating to a more actively maintained society management solution if vendor support is unavailable

# Example .htaccess configuration to restrict admin access
<Directory "/path/to/society_management/admin">
    # Restrict to local network only
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
    
    # Require authentication
    AuthType Basic
    AuthName "Restricted Admin Area"
    AuthUserFile /path/to/.htpasswd
    Require valid-user
</Directory>
