CVE-2026-7002: KLiK SocialMediaWebsite SQLi Vulnerability

CVE-2026-7002 Overview

A SQL Injection vulnerability has been identified in KLiK SocialMediaWebsite versions up to 1.0.1. This vulnerability affects the Private Message Handler component, specifically within the file /includes/get_message_ajax.php. By manipulating the c_id argument, an attacker can inject malicious SQL queries, potentially compromising the underlying database. The vulnerability is remotely exploitable without authentication requirements.

Critical Impact
Unauthenticated attackers can remotely exploit this SQL injection vulnerability to access, modify, or delete sensitive user data including private messages and potentially other database contents.

Affected Products

KLiK SocialMediaWebsite up to version 1.0.1
/includes/get_message_ajax.php - Private Message Handler component

Technical Details for CVE-2026-7002

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) exists in the Private Message Handler component of KLiK SocialMediaWebsite. The vulnerability allows remote attackers to execute arbitrary SQL commands through manipulation of the c_id parameter in the get_message_ajax.php file.

The attack can be launched remotely over the network, requires no special privileges or authentication, and does not depend on user interaction. Successful exploitation could result in unauthorized data access, data manipulation, and potential compromise of the application's database integrity.

Root Cause

The root cause of this vulnerability is improper input validation and sanitization of the c_id parameter within the Private Message Handler. The application fails to properly neutralize special characters and SQL syntax before incorporating user-supplied input into database queries, allowing attackers to break out of the intended query context and inject their own SQL statements.

Attack Vector

The vulnerability is exploitable via network-based attacks targeting the /includes/get_message_ajax.php endpoint. An attacker can craft malicious requests containing SQL injection payloads in the c_id parameter. Since no authentication is required, any remote attacker with network access to the vulnerable application can attempt exploitation.

The attack flow involves sending specially crafted HTTP requests to the vulnerable endpoint, where the malicious c_id value is processed without adequate sanitization, resulting in the execution of attacker-controlled SQL queries against the backend database. For technical details, refer to the VulDB Vulnerability Entry.

Detection Methods for CVE-2026-7002

Indicators of Compromise

Unusual or malformed requests to /includes/get_message_ajax.php containing SQL syntax characters such as single quotes, double dashes, or UNION statements in the c_id parameter
Database error messages in application logs indicating SQL syntax errors
Unexpected database queries or access patterns involving the private messages table
Evidence of data exfiltration or unauthorized access to user private messages

Detection Strategies

Deploy Web Application Firewalls (WAF) with SQL injection detection rules monitoring requests to the affected endpoint
Implement application-level logging to capture all requests to /includes/get_message_ajax.php with parameter values
Configure database audit logging to detect anomalous query patterns
Use intrusion detection systems (IDS) with signatures for common SQL injection patterns

Monitoring Recommendations

Monitor HTTP access logs for requests containing SQL metacharacters in the c_id parameter
Set up alerts for database errors related to SQL syntax or unauthorized query attempts
Review application logs for unusual patterns in private message retrieval
Implement rate limiting on the affected endpoint to slow potential automated exploitation attempts

How to Mitigate CVE-2026-7002

Immediate Actions Required

Restrict or disable access to /includes/get_message_ajax.php until a patch is applied
Implement input validation on the c_id parameter to accept only numeric values
Deploy a Web Application Firewall (WAF) rule to block requests with SQL injection patterns
Review database logs for evidence of prior exploitation attempts

Patch Information

No official patch information is currently available from the vendor. Organizations should monitor the VulDB submission and vendor channels for updates regarding security patches. In the absence of an official fix, implement the workarounds below to reduce risk.

Workarounds

Apply strict input validation ensuring the c_id parameter accepts only integer values
Use prepared statements with parameterized queries when modifying the vulnerable code
Implement a WAF rule to filter SQL injection attempts targeting the affected endpoint
Consider temporarily disabling the private messaging functionality until a proper fix is available

bash

# Example WAF rule for ModSecurity to block SQL injection on affected endpoint
SecRule REQUEST_URI "@contains /includes/get_message_ajax.php" \
    "id:100001,phase:2,deny,status:403,\
    chain"
    SecRule ARGS:c_id "!@rx ^[0-9]+$" \
        "msg:'Potential SQL Injection in c_id parameter'"
