Loading vulnerability…
VERITAS Backup Exec Server (beserver.exe) versions 9.0 through 10.0 for Windows expose an RPC interface on TCP port 6106 that allows remote, unauthenticated attackers to modify the Windows registry by invoking specific methods. The vulnerability arises from insufficient authentication and authorization checks on the RPC interface, permitting arbitrary registry modifications.

This repository contains a single Metasploit auxiliary module (modules/auxiliary/admin/backupexec/registry.rb) targeting a remote registry access vulnerability (CVE-2005-0771) in the Veritas Backup Exec Windows Server RPC service. The module allows an attacker with network access to port 6106/tcp on a vulnerable Backup Exec server to remotely read, write, and enumerate Windows registry keys. The module provides two main actions: dumping system information (such as OS version, registered owner, CPU, and current user) and setting a custom logon notice on the target system. The exploit leverages the DCERPC interface (UUID 93841fd0-16ce-11ce-850d-02608c44967b) to communicate with the service. The code is written in Ruby and is designed to be run within the Metasploit Framework. The module is operational and provides real impact (registry manipulation and information disclosure) but does not include a customizable payload beyond the provided actions.
