CVE-2025-11033: Kidaze Courseselectionsystem SQLi Flaw

CVE-2025-11033 Overview

A SQL Injection vulnerability has been identified in kidaze CourseSelectionSystem, affecting the file /Profilers/PriProfile/COUNT3s7.php. The vulnerability exists due to improper sanitization of the cbe parameter, allowing remote attackers to manipulate SQL queries and potentially compromise the underlying database. This product uses a rolling release model, meaning no specific version numbers are available for affected or patched releases.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive data from the CourseSelectionSystem database without authentication.

Affected Products

• kidaze CourseSelectionSystem (up to commit 42cd892b40a18d50bd4ed1905fa89f939173a464)

Technical Details for CVE-2025-11033

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands within the CourseSelectionSystem application. The vulnerable endpoint at /Profilers/PriProfile/COUNT3s7.php accepts user-controlled input through the cbe parameter without adequate validation or sanitization.

The attack can be initiated remotely over the network without requiring any prior authentication or user interaction. Successful exploitation could allow an attacker to read sensitive information from the database, modify or delete data, and potentially execute administrative operations depending on the database privileges assigned to the application.

Root Cause

The root cause of this vulnerability is a failure to properly sanitize user input before incorporating it into SQL queries (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component). The cbe parameter value is directly concatenated or interpolated into SQL statements without using parameterized queries or prepared statements, enabling attackers to inject malicious SQL syntax.

Attack Vector

The vulnerability is exploitable remotely via network access. An attacker can craft malicious HTTP requests targeting the /Profilers/PriProfile/COUNT3s7.php endpoint with specially crafted values for the cbe parameter. These malicious values contain SQL syntax that alters the intended query logic, potentially allowing data extraction via UNION-based injection, blind SQL injection techniques, or error-based injection depending on the application's error handling configuration.

The exploit has been publicly disclosed, increasing the risk of exploitation in the wild. For technical details, refer to the GitHub CVE Issue Discussion.

Detection Methods for CVE-2025-11033

Indicators of Compromise

• HTTP requests to /Profilers/PriProfile/COUNT3s7.php containing SQL syntax characters in the cbe parameter (e.g., single quotes, UNION statements, comment sequences)
• Unusual database query patterns or errors in application logs indicating malformed SQL statements
• Unexpected database access patterns or data exfiltration attempts from the CourseSelectionSystem database

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the cbe parameter
• Monitor application logs for SQL error messages or unusual query execution times that may indicate injection attempts
• Implement database activity monitoring to detect unauthorized queries or data access patterns

Monitoring Recommendations

• Enable detailed logging for the /Profilers/PriProfile/COUNT3s7.php endpoint and review logs for suspicious input patterns
• Configure alerting for database errors that may indicate SQL injection probing
• Monitor network traffic for unusual data volumes from the database server that could indicate data exfiltration

How to Mitigate CVE-2025-11033

Immediate Actions Required

• Restrict access to the vulnerable endpoint /Profilers/PriProfile/COUNT3s7.php until a patch is available
• Implement input validation and sanitization for the cbe parameter at the web server or WAF level
• Review database user privileges to ensure the application uses least-privilege access
• Monitor the VulDB Entry #325980 for updates on patches or mitigations

Patch Information

As of the last update on October 8, 2025, no official patch version has been released. The CourseSelectionSystem uses a rolling release model without versioned releases, making traditional patch tracking difficult. Administrators should monitor the project's repository for commits addressing this SQL injection vulnerability in /Profilers/PriProfile/COUNT3s7.php.

Additional technical information is available at the VulDB CTI ID #325980.

Workarounds

• Deploy a Web Application Firewall with SQL injection protection rules specifically targeting the cbe parameter
• Implement server-side input validation to reject requests containing SQL metacharacters in the cbe parameter
• Consider disabling or removing the affected PHP file if the functionality is not critical to operations
• Isolate the database server and restrict network access to minimize potential impact from successful exploitation

# Example: Block access to vulnerable endpoint via Apache .htaccess
<Files "COUNT3s7.php">
    Order deny,allow
    Deny from all
    # Allow only from trusted IP addresses if needed
    # Allow from 192.168.1.0/24
</Files>
