CVE-2025-40692: Phpgurukul Fire Reporting SQLi Flaw

CVE-2025-40692 Overview

A critical SQL Injection vulnerability has been identified in PHPGurukul Online Fire Reporting System version 1.2. This vulnerability exists in the requestid parameter within the /ofrs/details.php endpoint, allowing unauthenticated attackers to retrieve, create, update, and delete database records. Successful exploitation could lead to complete compromise of the application's database, enabling attackers to access sensitive fire reporting data, manipulate records, or cause significant data loss.

Critical Impact

Unauthenticated attackers can fully compromise the database through SQL Injection, potentially accessing sensitive fire incident reports, user credentials, and administrative data while having the ability to modify or delete critical records.

Technical Details for CVE-2025-40692

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) affects the Online Fire Reporting System, a PHP-based web application used for managing fire incident reports. The vulnerability exists because user-supplied input in the requestid parameter is not properly sanitized before being incorporated into SQL queries.

The vulnerable endpoint /ofrs/details.php accepts a requestid parameter that is directly concatenated or interpolated into database queries without adequate input validation or parameterized query usage. This allows attackers to inject arbitrary SQL statements that will be executed by the database server with the same privileges as the web application.

Given the network-accessible nature of this vulnerability and the lack of authentication requirements, any remote attacker can exploit this flaw to gain unauthorized access to the entire database. The impact encompasses confidentiality, integrity, and availability of the stored data.

Root Cause

The root cause of this vulnerability is improper input validation and the use of dynamic SQL queries without parameterization. The application fails to sanitize the requestid parameter before including it in SQL statements, violating the secure coding principle of never trusting user input. This is a classic SQL Injection pattern where concatenating user input directly into SQL queries creates an injection point.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker can craft malicious HTTP requests to the /ofrs/details.php endpoint, injecting SQL payloads through the requestid parameter. These payloads can be designed to extract data using UNION-based or error-based techniques, modify existing records with UPDATE statements, insert malicious data, or delete records using destructive SQL commands. The exploitation is straightforward and can be automated using common SQL injection tools.

Detection Methods for CVE-2025-40692

Indicators of Compromise

• Unusual or malformed requests to /ofrs/details.php containing SQL syntax characters such as single quotes, double dashes, UNION keywords, or semicolons in the requestid parameter
• Database error messages in application logs indicating SQL syntax errors or unexpected query behavior
• Unexpected database modifications or deletions in fire reporting records
• Evidence of data exfiltration attempts in web server access logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the requestid parameter
• Monitor application logs for requests containing SQL keywords (UNION, SELECT, DROP, INSERT, UPDATE, DELETE) in GET/POST parameters
• Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for common SQL injection payloads

Monitoring Recommendations

• Enable detailed logging on the web server to capture full request URIs and parameter values for forensic analysis
• Set up alerts for database errors that may indicate exploitation attempts
• Monitor for unusual database query patterns, especially queries returning large result sets or accessing multiple tables
• Review access logs for automated scanning activity targeting the vulnerable endpoint

How to Mitigate CVE-2025-40692

Immediate Actions Required

• Restrict access to the /ofrs/details.php endpoint using network-level controls or authentication requirements until a patch is available
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules to filter malicious requests
• Review database logs for signs of prior exploitation and assess potential data compromise
• Consider taking the application offline if it contains sensitive data and cannot be adequately protected

Patch Information

As of the last NVD update on 2025-09-12, no vendor patch information is available. Organizations should monitor the INCIBE Security Notice on PHPGurukul Vulnerabilities for updates and contact PHPGurukul for remediation guidance.

Workarounds

• Implement input validation by modifying the application code to use prepared statements with parameterized queries for all database interactions
• Add server-side validation to ensure the requestid parameter contains only expected numeric or alphanumeric values
• Deploy a reverse proxy or WAF in front of the application to filter SQL injection attempts
• Apply the principle of least privilege to the database user account used by the application, limiting permissions to only necessary operations
• Implement network segmentation to limit access to the application from trusted networks only
