CVE-2025-2665: PHPGurukul Security Guards SQLI Flaw

CVE-2025-2665 Overview

A SQL injection vulnerability has been identified in PHPGurukul Online Security Guards Hiring System version 1.0. The vulnerability exists in the /admin/bwdates-reports-details.php file, where user-supplied input via the fromdate and todate parameters is not properly sanitized before being used in database queries. This allows remote attackers to inject malicious SQL commands that can compromise the underlying database.

Critical Impact

Unauthenticated remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially achieve full database compromise through the admin reports functionality.

Technical Details for CVE-2025-2665

Vulnerability Analysis

This vulnerability falls under SQL Injection (CWE-89) and the broader category of Injection (CWE-74). The flaw resides in the date-based report generation functionality within the administrative panel. When an administrator generates reports using date range filters, the application passes the fromdate and todate parameters directly into SQL queries without proper input validation or parameterized queries.

The network-accessible attack surface requires no user interaction and can be exploited without authentication or special privileges. Successful exploitation could allow attackers to read arbitrary database contents, including user credentials, personal information, and sensitive business data stored within the hiring system.

Root Cause

The root cause is improper input validation and lack of prepared statements or parameterized queries in the PHP code handling the date range report functionality. The bwdates-reports-details.php file directly concatenates user-supplied date values into SQL query strings, creating a classic SQL injection vulnerability.

Attack Vector

An attacker can craft malicious HTTP requests containing SQL injection payloads in the fromdate or todate GET/POST parameters. Since this is a network-based attack vector with low complexity, attackers can exploit this vulnerability remotely without any authentication or user interaction. The attack targets the admin reports section where date range filtering is implemented.

The vulnerability has been publicly disclosed with exploit details available through the GitHub CVE Issue Tracking repository.

Detection Methods for CVE-2025-2665

Indicators of Compromise

• HTTP requests to /admin/bwdates-reports-details.php containing SQL meta-characters such as single quotes, UNION keywords, or comment sequences in the fromdate or todate parameters
• Database error messages in application logs indicating malformed SQL queries originating from the reports functionality
• Unusual database queries or access patterns involving the reports tables
• Evidence of time-based blind SQL injection attempts through abnormal response delays

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests targeting the affected endpoint
• Monitor application and database logs for SQL syntax errors or unusual query patterns from the bwdates-reports-details.php file
• Deploy intrusion detection signatures to identify common SQL injection attack payloads in the fromdate and todate parameters
• Review HTTP access logs for suspicious requests with encoded characters or SQL keywords

Monitoring Recommendations

• Enable detailed logging on the web server for all requests to the /admin/ directory
• Configure database audit logging to capture queries executed by the application user account
• Set up alerting for any database errors or exceptions related to the reporting functionality
• Monitor for bulk data extraction attempts or unusual SELECT query volumes

How to Mitigate CVE-2025-2665

Immediate Actions Required

• Restrict network access to the administrative panel to trusted IP addresses only
• Implement Web Application Firewall rules to block SQL injection attempts targeting the affected parameters
• If possible, disable or remove access to the /admin/bwdates-reports-details.php file until a patch is available
• Review application logs for evidence of prior exploitation attempts

Patch Information

As of the last modification date (2025-05-13), no official patch from PHPGurukul has been publicly documented for this vulnerability. Organizations should monitor the PHP Gurukul Security Resource for vendor updates and security announcements. Additional technical details are available through the VulDB Entry #300687.

Workarounds

• Implement input validation on the fromdate and todate parameters to accept only valid date formats before processing
• Modify the vulnerable PHP code to use prepared statements with parameterized queries instead of string concatenation
• Deploy a reverse proxy or WAF with SQL injection filtering rules in front of the application
• Restrict administrative panel access to internal networks or VPN-connected users only
• Consider taking the affected reporting functionality offline until proper remediation can be implemented
