This affects all organizations using the vulnerable version of the software. Attackers can gain complete control over affected systems.
💻 Affected Systems
- TMS Global Software TMS Management Console
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining administrative privileges, data exfiltration, ransomware deployment, and lateral movement across the network.
Likely Case
Remote code execution leading to web shell installation, credential theft, and persistence on the affected server.
If Mitigated
Attack blocked at perimeter with file upload restrictions, resulting in failed exploitation attempts logged for analysis.
🎯 Exploit Status
The GitHub reference suggests proof-of-concept code exists. File upload vulnerabilities are commonly weaponized due to their simplicity and impact.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://tmsglobalsoft.com
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If patch available, download and apply following vendor instructions. 3. Verify fix by testing the vulnerable endpoint.
🔧 Temporary Workarounds
Web Application Firewall Rules
allImplement WAF rules to block malicious file uploads to the vulnerable endpoint
WAF specific - configure rules to block file uploads to /Customer/AddEdit or restrict file types to images only
Network Segmentation
allRestrict access to the TMS Management Console to trusted IP addresses only
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="TRUSTED_IP" port port="443" protocol="tcp" accept'
netsh advfirewall firewall add rule name="TMS Access" dir=in action=allow protocol=TCP localport=443 remoteip=TRUSTED_IP
🧯 If You Can't Patch
- Disable the Logo upload functionality in the TMS Management Console
- Implement strict file type validation and size limits on the web server level
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a test file (e.g., .txt with harmless content) to the /Customer/AddEdit endpoint's Logo upload feature and check if it's accepted without proper validation.Check Version:
Check the TMS Management Console interface or configuration files for version information (typically in About section or web.config)Verify Fix Applied:
Test the same file upload attempt after applying controls - should be rejected with proper error messages.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to /Customer/AddEdit
- Uploads of non-image file types (.php, .asp, .jsp, .exe)
- Large number of upload attempts from single IP
Network Indicators:
- POST requests to /Customer/AddEdit with file upload content
- Unusual outbound connections from TMS server after file upload
SIEM Query:
source="web_logs" AND uri_path="/Customer/AddEdit" AND (file_extension="php" OR file_extension="asp" OR file_extension="jsp" OR file_extension="exe")
