CVE-2025-8469
📋 TL;DR
A critical SQL injection vulnerability in SourceCodester Online Hotel Reservation System 1.0 allows remote attackers to execute arbitrary SQL commands via the ID parameter in /admin/deletegallery.php. This affects all deployments of version 1.0, potentially compromising the entire database and system. Attackers can exploit this without authentication to steal, modify, or delete sensitive hotel reservation data.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, privilege escalation to admin, and potential remote code execution via database functions.
Likely Case
Unauthenticated attackers extracting sensitive guest information (personal data, payment details), modifying reservations, and gaining administrative access to the system.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, with database permissions restricted to prevent data manipulation.
🎯 Exploit Status
Exploit details are publicly available on GitHub. The SQL injection is straightforward with no authentication required, making weaponization highly probable.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider implementing parameterized queries and input validation in /admin/deletegallery.php.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to ensure ID parameter contains only numeric values before processing.
Modify /admin/deletegallery.php to include: if(!is_numeric($_GET['ID'])) { die('Invalid input'); }
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the deletegallery.php endpoint.
Add WAF rule: Block requests to /admin/deletegallery.php with non-numeric ID parameters or SQL keywords in ID parameter
🧯 If You Can't Patch
- Restrict access to /admin/ directory using IP whitelisting or authentication requirements
- Disable or rename /admin/deletegallery.php file if functionality is not required
🔍 How to Verify
Check if Vulnerable:
Test by sending a request to /admin/deletegallery.php?ID=1' OR '1'='1 and checking for SQL errors or unexpected behavior.Check Version:
Check the software version in admin panel or review source code comments for version 1.0 indicators.Verify Fix Applied:
After implementing fixes, test with malicious payloads to confirm they are rejected or properly handled without SQL execution.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple requests to /admin/deletegallery.php with suspicious ID parameters
- Failed login attempts followed by deletegallery.php access
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, INSERT) in URL parameters
- Unusual traffic patterns to admin endpoints from external IPs
SIEM Query:
source="web_logs" AND (url="/admin/deletegallery.php" AND (query="*'*" OR query="*OR*" OR query="*UNION*"))
