Network Segmentation
windowsRestrict access to Disk Sorter web interface using firewall rules
netsh advfirewall firewall add rule name="Block Disk Sorter Web" dir=in action=block protocol=TCP localport=80,443 remoteip=any
Disable Web Interface
windowsTemporarily disable the vulnerable web interface component
sc stop "Disk Sorter Web Service"
sc config "Disk Sorter Web Service" start= disabled
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the Disk Sorter web interface
- Deploy web application firewall (WAF) rules to block buffer overflow attempts in GET requests
🔍 How to Verify
Check if Vulnerable:
Check Disk Sorter version in the application interface or installation directory. Versions 9.5.12 and earlier are vulnerable.Check Version:
Check the About section in Disk Sorter GUI or examine the installation directory for version files.Verify Fix Applied:
Verify the installed version is 9.5.13 or later and test that the web interface functions normally without allowing buffer overflow.📡 Detection & Monitoring
