CVE-2025-11473
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary SQL commands via the 'currsymbol' parameter in the /edit_curr.php file of SourceCodester Hotel and Lodge Management System 1.0. This can lead to unauthorized data access, modification, or deletion. All users running the affected version are vulnerable.
💻 Affected Systems
- SourceCodester Hotel and Lodge Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, and potential server takeover via SQL injection leading to remote code execution.
Likely Case
Unauthorized access to sensitive hotel management data (guest information, financial records, booking details) and potential data manipulation.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, restricting SQL injection attempts.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If patch available, download and apply. 3. Replace vulnerable /edit_curr.php file with patched version. 4. Test functionality after patching.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the currsymbol parameter
Replace raw SQL queries with prepared statements: $stmt = $conn->prepare('UPDATE currency SET symbol = ? WHERE id = ?'); $stmt->bind_param('si', $currsymbol, $id);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting /edit_curr.php
ModSecurity rule: SecRule ARGS:currsymbol "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
🧯 If You Can't Patch
- Block external access to /edit_curr.php using firewall rules or web server configuration
- Implement network segmentation to isolate the vulnerable system from critical infrastructure
🔍 How to Verify
Check if Vulnerable:
Test the /edit_curr.php endpoint with SQL injection payloads in the currsymbol parameter (e.g., currsymbol=' OR '1'='1)Check Version:
Check PHP files for version comments or review system documentationVerify Fix Applied:
Attempt SQL injection tests after patching; successful queries should be blocked or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple requests to /edit_curr.php with suspicious parameters
- Database query errors containing SQL syntax
Network Indicators:
- HTTP POST requests to /edit_curr.php containing SQL keywords (UNION, SELECT, INSERT) in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri_path="/edit_curr.php" AND (param="*currsymbol*" AND value="*' OR*" OR value="*UNION*" OR value="*SELECT*")
