CVE-2025-40690: Phpgurukul Fire Reporting System SQLi

CVE-2025-40690 Overview

CVE-2025-40690 is a critical SQL Injection vulnerability affecting PHPGurukul's Online Fire Reporting System version 1.2. This vulnerability allows an unauthenticated attacker to manipulate database queries through the teamid parameter in the /ofrs/admin/edit-team.php endpoint, enabling unauthorized retrieval, creation, modification, and deletion of database records.

Critical Impact

Unauthenticated attackers can fully compromise the database through SQL injection, potentially exposing sensitive fire incident reports, user credentials, and administrative data while enabling complete data manipulation.

Affected Products

• PHPGurukul Online Fire Reporting System version 1.2
• Applications using the /ofrs/admin/edit-team.php endpoint with unvalidated teamid parameter

Technical Details for CVE-2025-40690

Vulnerability Analysis

This SQL Injection vulnerability exists in the administrative team management functionality of the Online Fire Reporting System. The application fails to properly sanitize or parameterize user input received through the teamid parameter before incorporating it into SQL queries. This allows attackers to inject malicious SQL statements that are executed directly against the backend database.

The vulnerability is accessible over the network without requiring authentication, meaning any attacker with network access to the application can exploit this flaw. The attack complexity is low, as no special conditions or sophisticated techniques are needed to successfully exploit the injection point.

Root Cause

The root cause is improper input validation and the absence of parameterized queries (prepared statements) in the edit-team.php script. The teamid parameter value is directly concatenated into SQL query strings without sanitization, escaping, or validation. This classic SQL injection pattern (CWE-89) allows attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack is network-based, targeting the /ofrs/admin/edit-team.php endpoint. An attacker crafts malicious HTTP requests containing SQL injection payloads in the teamid parameter. Since the parameter is expected to contain a numeric team identifier, the application likely constructs queries such as SELECT * FROM teams WHERE teamid = [user_input]. By injecting SQL syntax like 1 OR 1=1 or UNION-based payloads, attackers can extract data from other tables, modify records, or potentially escalate to operating system command execution depending on database permissions.

The vulnerability requires no user interaction and no prior authentication, making it particularly dangerous for internet-exposed installations. Successful exploitation can result in complete compromise of data confidentiality, integrity, and availability within the database.

Detection Methods for CVE-2025-40690

Indicators of Compromise

• Unusual SQL error messages in application or web server logs referencing the edit-team.php endpoint
• HTTP requests to /ofrs/admin/edit-team.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences (--, #, /*)
• Unexpected database query patterns or unauthorized data access in database audit logs
• Evidence of data exfiltration or modification in the fire reporting system's team records

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /ofrs/admin/edit-team.php
• Implement application-level logging for all requests containing the teamid parameter and monitor for anomalous input patterns
• Configure database audit logging to track queries executed against team-related tables
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Continuously monitor web server access logs for requests to the vulnerable endpoint containing suspicious characters or SQL syntax
• Establish baseline database query patterns and alert on deviations, particularly bulk data retrievals or modifications
• Implement real-time alerting for WAF-blocked SQL injection attempts targeting this application

How to Mitigate CVE-2025-40690

Immediate Actions Required

• Restrict network access to the /ofrs/admin/edit-team.php endpoint using firewall rules or .htaccess configurations until a patch is applied
• Implement input validation to ensure the teamid parameter only accepts numeric values
• Deploy a Web Application Firewall with SQL injection protection rules enabled
• Review database permissions to ensure the application database user has minimum required privileges

Patch Information

No official vendor patch was available at the time of publication. Organizations should monitor the INCIBE Security Notice and PHPGurukul's official channels for security updates. Consider engaging a security professional to implement code-level fixes if a vendor patch is not forthcoming.

Workarounds

• Implement parameterized queries (prepared statements) in the edit-team.php script to prevent SQL injection
• Add strict input validation requiring the teamid parameter to be a positive integer before processing
• Restrict access to the administrative panel to trusted IP addresses only
• Consider placing the application behind a reverse proxy with SQL injection filtering capabilities

# Example: Apache .htaccess to restrict access to admin directory
<Directory "/var/www/html/ofrs/admin">
    # Restrict to internal network only
    Require ip 10.0.0.0/8 192.168.0.0/16 172.16.0.0/12
    # Alternatively, require authentication
    # AuthType Basic
    # AuthName "Restricted Access"
    # AuthUserFile /etc/apache2/.htpasswd
    # Require valid-user
</Directory>
