Loading vulnerability…
Unitrends Backup before version 10.0.0 contains an authentication-bypass vulnerability in the proprietary bpserverd protocol when the service is invoked through xinetd. A remote attacker can bypass authentication and execute arbitrary commands with root privileges on the affected system.

This repository contains a single Metasploit module (modules/exploits/linux/misc/ueb9_bpserverd.rb) targeting Unitrends Enterprise Backup (UEB) version 9.x. The exploit leverages an authentication bypass vulnerability (CVE-2017-12477) in the proprietary bpserverd protocol, which is exposed via xinetd on TCP port 1743. The module connects to the service, retrieves a secondary port, and then sends a crafted command buffer to achieve remote code execution as root. The default payload is a Meterpreter reverse shell (linux/x86/meterpreter/reverse_tcp), delivered using Metasploit's command stager with the 'printf' flavor. The exploit is operational and provides full remote code execution if the target is vulnerable. The repository is structured as a typical Metasploit module, with all logic contained in a single Ruby file.
