📦 What is this software?
Dormsystem by Dormsystem Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized access to sensitive student/housing data, administrative privilege escalation, and database manipulation.
If Mitigated
Limited impact with proper input validation and parameterized queries in place, potentially only error messages exposed.
🎯 Exploit Status
SQL injection vulnerabilities are commonly weaponized. The GitHub issue shows proof of concept exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://github.com/Tooonyy/dormsystem/issues/1
Restart Required: No
Instructions:
1. Review the GitHub issue for community fixes. 2. Manually implement parameterized queries in admin.php. 3. Validate and sanitize all user inputs. 4. Test thoroughly before deployment.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
Input Validation Filter
allImplement input validation to reject SQL keywords and special characters in admin.php parameters.
🧯 If You Can't Patch
- Isolate the dormsystem application in a segmented network with strict access controls.
- Implement database-level protections: use least privilege accounts, enable database auditing, and restrict network access to database.
🔍 How to Verify
Check if Vulnerable:
Test admin.php endpoint with SQL injection payloads like ' OR '1'='1 in parameters and observe database errors or unexpected behavior.Check Version:
Check the software version in the application interface or configuration files.Verify Fix Applied:
Attempt SQL injection tests after implementing fixes and confirm no database errors or unauthorized access occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in web server logs
- Multiple failed login attempts to admin.php
- Database error messages containing SQL fragments
Network Indicators:
- HTTP requests to admin.php with SQL keywords in parameters
- Unusual database query patterns from web server
SIEM Query:
source="web_server" AND uri="*admin.php*" AND (param="*' OR*" OR param="*;--*" OR param="*UNION*" OR param="*SELECT*" OR param="*INSERT*")
