CVE-2025-28072
📋 TL;DR
PHPGurukul Pre-School Enrollment System contains a directory traversal vulnerability in manage-teachers.php that allows attackers to access files outside the intended directory. This affects all systems running the vulnerable software version. Attackers can potentially read sensitive files like configuration files or source code.
💻 Affected Systems
- PHPGurukul Pre-School Enrollment System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through reading sensitive configuration files containing database credentials, followed by database access and potential data exfiltration or further attacks.
Likely Case
Unauthorized reading of sensitive files such as configuration files, source code, or other system files containing credentials or sensitive information.
If Mitigated
Limited impact with proper file permissions and web server configuration restricting access to sensitive directories.
🎯 Exploit Status
Directory traversal vulnerabilities are typically easy to exploit with simple HTTP requests using ../ sequences. The GitHub reference suggests proof-of-concept details are available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check PHPGurukul website or repository for security updates. 2. Apply any available patches for the Pre-School Enrollment System. 3. Validate the fix by testing the directory traversal vulnerability.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement proper input validation to reject directory traversal sequences in file parameters
Modify manage-teachers.php to validate and sanitize all file path inputs using functions like realpath() and basename()
Web Server Configuration
allConfigure web server to restrict file access to specific directories
For Apache: Set appropriate Directory and Location directives in httpd.conf
For Nginx: Configure location blocks with proper root and try_files directives
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block directory traversal patterns in HTTP requests
- Restrict network access to the application using firewall rules to limit exposure
🔍 How to Verify
Check if Vulnerable:
Test by accessing manage-teachers.php with directory traversal payloads like ?file=../../../etc/passwd and check if sensitive files are returned
Check Version:
Check application version in admin panel or by examining source code files for version identifiers
Verify Fix Applied:
Attempt the same directory traversal attacks after applying fixes and verify they are blocked or return error messages
