CVE-2026-1119: Society Management System SQLi Vulnerability

CVE-2026-1119 Overview

A SQL injection vulnerability has been identified in itsourcecode Society Management System version 1.0. The vulnerability exists in an unknown function within the file /admin/delete_activity.php. By manipulating the activity_id parameter, an attacker can inject malicious SQL commands. This vulnerability can be exploited remotely, and exploit code has been published publicly.

Critical Impact

Remote attackers can exploit this SQL injection flaw to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise without authentication.

Affected Products

• itsourcecode Society Management System 1.0
• /admin/delete_activity.php endpoint

Technical Details for CVE-2026-1119

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the administrative functionality of the Society Management System. The vulnerable endpoint /admin/delete_activity.php accepts user-supplied input through the activity_id parameter without proper sanitization or parameterized queries.

The attack can be executed remotely over the network with low complexity, requiring no authentication or user interaction. Successful exploitation could result in limited impact to confidentiality, integrity, and availability of the affected system. The exploit has been publicly disclosed, increasing the risk of active exploitation in the wild.

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries in the /admin/delete_activity.php file. The activity_id parameter is directly incorporated into SQL queries without proper escaping or prepared statements, allowing attackers to inject arbitrary SQL syntax that modifies the intended query logic.

Attack Vector

The vulnerability is exploitable via network-based attacks targeting the administrative interface. An attacker can craft malicious HTTP requests to the /admin/delete_activity.php endpoint with specially crafted activity_id values containing SQL injection payloads. Since this is an administrative endpoint related to activity deletion, the injected SQL could be used to:

• Extract sensitive data from the database
• Modify or delete records beyond the intended scope
• Bypass authentication mechanisms
• Potentially escalate privileges within the application

The attack requires no prior authentication or special privileges, making it particularly dangerous for publicly accessible deployments of this application.

Detection Methods for CVE-2026-1119

Indicators of Compromise

• Unusual SQL syntax or error messages appearing in web server logs for /admin/delete_activity.php
• Unexpected database queries containing UNION SELECT, OR 1=1, or other common SQL injection patterns
• Abnormal access patterns to the administrative interface from external IP addresses
• Database audit logs showing unauthorized data access or modification operations

Detection Strategies

• Implement web application firewall (WAF) rules to detect SQL injection patterns in the activity_id parameter
• Monitor HTTP access logs for requests to /admin/delete_activity.php containing suspicious characters such as single quotes, double dashes, or UNION keywords
• Enable database query logging and alert on malformed or unusual queries originating from the web application
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Configure real-time alerting for any access attempts to /admin/delete_activity.php from untrusted networks
• Implement rate limiting on administrative endpoints to slow down automated exploitation attempts
• Monitor database connection pools for abnormal activity or connection exhaustion
• Review web server and application logs regularly for signs of reconnaissance or exploitation attempts

How to Mitigate CVE-2026-1119

Immediate Actions Required

• Restrict network access to the /admin/delete_activity.php endpoint using IP whitelisting or VPN requirements
• Deploy a web application firewall (WAF) with SQL injection detection rules in front of the application
• If possible, disable or remove the vulnerable functionality until a patch is available
• Implement input validation at the network perimeter to block requests with SQL injection patterns

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. System administrators should monitor the ITSourceCode homepage for updates. Additional technical details and discussion are available through the GitHub Issue Discussion and VulDB #341711.

Workarounds

• Implement prepared statements or parameterized queries in the source code if you have development access
• Add input validation to the activity_id parameter to ensure it only accepts numeric values
• Deploy a reverse proxy or WAF that can filter malicious SQL injection payloads
• Isolate the application server and database on a segmented network to limit the blast radius of a successful attack
• Consider disabling the vulnerable endpoint entirely if the delete activity functionality is not business-critical

# Example: Restrict access to admin directory via .htaccess
# Place in /admin/.htaccess
<Files "delete_activity.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
