📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation, or system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized access to sensitive financial transaction data, user information, and potential data manipulation in the currency exchange database.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub and vuldb. SQL injection via ID parameter requires minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize the ID parameter before processing.
Modify /viewserial.php to validate ID parameter as integer: if(!is_numeric($_GET['ID'])) { die('Invalid input'); }
WAF Rule
allImplement web application firewall rules to block SQL injection patterns.
Add WAF rule: SecRule ARGS:ID "@rx (?i)(union|select|insert|update|delete|drop|--|#|\/\*|\*\/)" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict network segmentation
- Implement database user with minimal required permissions (read-only if possible)
🔍 How to Verify
Check if Vulnerable:
Test /viewserial.php with SQL injection payloads like: /viewserial.php?ID=1' OR '1'='1Check Version:
Check application version in source code or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and return error or sanitized response.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests to /viewserial.php with suspicious parameters
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, etc.) in URL parameters
SIEM Query:
source="web_logs" url="*viewserial.php*" AND (param="*union*" OR param="*select*" OR param="*' OR '*")
