CVE-2025-12938: Online Admission System SQLi Vulnerability

CVE-2025-12938 Overview

A SQL injection vulnerability has been identified in Projectworlds Online Admission System version 1.0. This vulnerability affects the /process_login.php file, where improper handling of the keywords parameter allows attackers to inject malicious SQL queries. The attack can be initiated remotely without authentication, potentially allowing unauthorized access to sensitive database contents, data manipulation, or complete system compromise.

Critical Impact

This SQL injection vulnerability in a publicly accessible login processing endpoint could enable attackers to bypass authentication, exfiltrate sensitive student admission data, or manipulate database records.

Technical Details for CVE-2025-12938

Vulnerability Analysis

This vulnerability is classified as SQL Injection (CWE-89) and more broadly as Injection (CWE-74). The flaw exists in the /process_login.php file, which processes user login requests. The keywords parameter is passed directly into SQL queries without proper sanitization or parameterization, allowing an attacker to craft malicious input that modifies the intended SQL query structure.

SQL injection vulnerabilities of this type are particularly dangerous in authentication endpoints because they can enable complete authentication bypass. An attacker could potentially extract the entire database schema, retrieve sensitive user credentials and admission records, modify or delete data, or in some database configurations, achieve command execution on the underlying server.

The vulnerability is remotely exploitable and requires no prior authentication, making it accessible to any attacker who can reach the web application. A public exploit has been referenced, increasing the risk of exploitation in the wild.

Root Cause

The root cause of this vulnerability is insufficient input validation and the use of dynamic SQL queries. The keywords parameter received from user input is directly concatenated into SQL statements rather than being handled through prepared statements or parameterized queries. This lack of input sanitization allows user-supplied data to escape the intended data context and be interpreted as SQL commands by the database engine.

Attack Vector

The attack vector is network-based, allowing remote exploitation without requiring authentication or user interaction. An attacker can send specially crafted HTTP requests to the /process_login.php endpoint, manipulating the keywords parameter to inject SQL commands.

For example, an attacker might submit input that terminates the original query and appends additional SQL statements, allowing them to enumerate database tables, extract sensitive information, or bypass authentication checks. The vulnerability has been publicly disclosed with exploit details available, as referenced in the GitHub CVE Issue Discussion.

Detection Methods for CVE-2025-12938

Indicators of Compromise

• Unusual or malformed HTTP requests targeting /process_login.php containing SQL syntax characters such as single quotes, double dashes, semicolons, or UNION/SELECT keywords
• Database error messages appearing in application logs or HTTP responses indicating SQL syntax errors
• Unexpected database queries in database audit logs, particularly those containing UNION, CONCAT, or information_schema references
• Anomalous database access patterns such as bulk data retrieval or access to system tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the keywords parameter
• Implement application-layer monitoring to identify requests with suspicious characters or SQL keywords targeting the login endpoint
• Enable detailed database query logging to capture and analyze queries executed through the application
• Configure intrusion detection systems (IDS) to alert on SQL injection attack signatures in network traffic

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /process_login.php with varying payloads, which may indicate automated injection testing
• Set up alerting for database errors related to SQL syntax issues originating from the application
• Review authentication logs for successful logins that lack corresponding valid credential submissions
• Implement rate limiting on the login endpoint to slow down automated exploitation attempts

How to Mitigate CVE-2025-12938

Immediate Actions Required

• If possible, restrict network access to the Online Admission System to trusted IP ranges or internal networks only
• Implement a Web Application Firewall with SQL injection protection rules as an immediate compensating control
• Review application and database logs for evidence of prior exploitation attempts
• Consider taking the application offline if it contains sensitive data and no patch is available

Patch Information

At the time of publication, no vendor patch has been released for this vulnerability. Projectworlds Online Admission System is an open-source project, and users should monitor the project repository and security advisories for updates. Additional technical details are available through VulDB #331662.

Workarounds

• Implement input validation at the application level to sanitize the keywords parameter before processing
• Deploy a reverse proxy or WAF configured to filter requests containing SQL injection patterns
• If modifying the source code is possible, convert dynamic SQL queries in /process_login.php to use prepared statements with parameterized queries
• Restrict database user privileges to the minimum necessary, preventing the application account from executing administrative commands

# Example: Block SQL injection patterns in Apache mod_rewrite
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} (\%27)|(\')|(\-\-)|(\%23)|(#) [NC,OR]
RewriteCond %{QUERY_STRING} (union|select|insert|drop|delete|update|concat|information_schema) [NC]
RewriteRule ^/process_login\.php - [F,L]
