CVE-2024-48283
📋 TL;DR
This vulnerability allows attackers to execute arbitrary SQL commands through the searchkey parameter in the admin search functionality of Phpgurukul User Registration & Login and User Management System 3.2. Attackers can potentially extract, modify, or delete database content, including sensitive user information and administrative credentials. All deployments of version 3.2 with the admin panel accessible are affected.
💻 Affected Systems
- Phpgurukul User Registration & Login and User Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, privilege escalation, and potential remote code execution through database functions.
Likely Case
Extraction of sensitive user data (passwords, personal information), administrative credential theft, and potential system takeover via admin panel access.
If Mitigated
Limited data exposure if proper input validation and parameterized queries are implemented, with database permissions restricting damage scope.
🎯 Exploit Status
Exploitation requires admin panel access; SQL injection is straightforward via searchkey parameter manipulation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Manually fix vulnerable code by implementing parameterized queries in search-result.php.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize searchkey parameter before processing.
Edit /admin/search-result.php to add input validation using PHP filter functions or regex patterns.
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in search parameters.
Configure WAF to detect and block SQL injection attempts in POST/GET parameters.
🧯 If You Can't Patch
- Restrict admin panel access to trusted IP addresses only using .htaccess or firewall rules.
- Disable the vulnerable search functionality by removing or commenting out the search-result.php file if not needed.
🔍 How to Verify
Check if Vulnerable:
Test the search functionality in admin panel with SQL injection payloads like ' OR '1'='1 in searchkey parameter.Check Version:
Check version in admin panel footer or configuration files; look for version 3.2 indicators.Verify Fix Applied:
Attempt the same SQL injection tests; successful fix should return no data or error messages indicating blocked injection.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs from admin IPs
- Multiple failed login attempts followed by search parameter anomalies
Network Indicators:
- HTTP requests to /admin/search-result.php with SQL keywords in parameters
- Abnormal response sizes from search queries
SIEM Query:
source="web_logs" AND uri="/admin/search-result.php" AND (param="searchkey" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "OR '1'='1")
