CVE-2025-11052: Kidaze Courseselectionsystem SQLi Flaw

CVE-2025-11052 Overview

A SQL injection vulnerability has been discovered in Kidaze CourseSelectionSystem version 1.0. The vulnerability exists in an unknown function within the file /Profilers/PriProfile/COUNT3s5.php. By manipulating the csslc argument, an attacker can inject malicious SQL commands. This attack can be initiated remotely, and exploit details have been publicly released, increasing the risk of active exploitation.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete database contents, potentially compromising the integrity and confidentiality of course selection data and user information stored in the CourseSelectionSystem application.

Technical Details for CVE-2025-11052

Vulnerability Analysis

This vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The flaw resides in the /Profilers/PriProfile/COUNT3s5.php file of the CourseSelectionSystem application. User-supplied input through the csslc parameter is not properly sanitized before being incorporated into SQL queries, allowing attackers to inject arbitrary SQL statements.

The network-accessible nature of this vulnerability means that any remote attacker who can reach the vulnerable endpoint can attempt exploitation without requiring prior authentication or user interaction. Successful exploitation could lead to unauthorized data access, data manipulation, or complete database compromise.

Root Cause

The root cause of this vulnerability is improper input validation and sanitization of the csslc parameter. The application fails to properly escape or parameterize user input before incorporating it into database queries. This allows specially crafted input containing SQL metacharacters to alter the intended query logic, enabling attackers to execute arbitrary SQL commands against the underlying database.

Attack Vector

The attack is network-based and can be executed remotely against the vulnerable /Profilers/PriProfile/COUNT3s5.php endpoint. An attacker crafts malicious input containing SQL injection payloads and submits it through the csslc parameter. Since no authentication appears to be required for the vulnerable endpoint, the attack surface is broad. The publicly available exploit information increases the likelihood that threat actors may attempt to leverage this vulnerability against unpatched systems.

Detection Methods for CVE-2025-11052

Indicators of Compromise

• Unusual HTTP requests to /Profilers/PriProfile/COUNT3s5.php containing SQL syntax characters such as single quotes, UNION, SELECT, OR 1=1, or other SQL keywords in the csslc parameter
• Database error messages appearing in application logs or HTTP responses indicating malformed SQL queries
• Unexpected database query patterns or excessive database connections originating from web application processes
• Evidence of data exfiltration or unauthorized database modifications in audit logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the csslc parameter
• Monitor web server access logs for requests to COUNT3s5.php with suspicious parameter values
• Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access attempts
• Use intrusion detection systems with SQL injection signature rules enabled

Monitoring Recommendations

• Enable verbose logging on the CourseSelectionSystem application to capture all requests to vulnerable endpoints
• Configure alerts for database errors that may indicate SQL injection attempts
• Monitor for unusual data access patterns that could indicate successful exploitation
• Review web application logs regularly for patterns matching known SQL injection techniques

How to Mitigate CVE-2025-11052

Immediate Actions Required

• Restrict access to the vulnerable endpoint /Profilers/PriProfile/COUNT3s5.php until a patch is applied
• Implement input validation on the csslc parameter to reject requests containing SQL metacharacters
• Deploy WAF rules to filter SQL injection attempts targeting the CourseSelectionSystem application
• Review database permissions to ensure the application uses least-privilege database accounts

Patch Information

No official vendor patch is currently available. Organizations should monitor the vendor's official channels and VulDB for updates regarding security patches. In the absence of an official fix, implementing the workarounds below is strongly recommended.

Workarounds

• Block or restrict network access to the /Profilers/PriProfile/COUNT3s5.php endpoint using firewall rules or reverse proxy configurations
• Implement parameterized queries or prepared statements in the application code if source code modification is possible
• Deploy a Web Application Firewall with SQL injection protection rules in front of the CourseSelectionSystem application
• Consider taking the affected application offline if it handles sensitive data and cannot be adequately protected

# Example: Block access to vulnerable endpoint using Apache .htaccess
<Files "COUNT3s5.php">
    Order deny,allow
    Deny from all
    # Allow only trusted IP addresses if needed
    # Allow from 192.168.1.0/24
</Files>
