version Sync Breeze Enterprise v9.4.28↗

• → Monitor for abnormally long username parameters in HTTP POST requests to the /login endpoint of Sync Breeze Enterprise's built-in web server, indicative of a stack-based buffer overflow attempt. ↗
• → Detect exploitation attempts via both HTTP GET and POST methods targeting the Sync Breeze Enterprise web interface, not just POST/login. ↗
• → Focus detection on Windows 7 SP1 x86 hosts running Sync Breeze Enterprise as the exploit has been confirmed working on this platform. ↗

• · The vulnerability affects multiple versions of Sync Breeze Enterprise (v9.4.28, v10.0.28, v10.1.16), not just the version cited in the CVE description. ↗
• · The CVE description references only the POST /login username parameter, but the Metasploit module indicates both HTTP GET and POST request methods are exploitable vectors. ↗
