Loading vulnerability…
CVE-2023-28502 is a pre-authentication stack-based buffer overflow vulnerability in the 'udadmin' service of Rocket Software UniData (prior to 8.2.4 build 3003) and UniVerse (prior to 11.3.5 build 1001 or 12.2.1 build 2002) on Linux. The vulnerability arises from improper bounds checking when processing network requests, allowing an attacker to send a specially crafted packet to the udadmin service and overflow a stack buffer. This can result in remote code execution as the root user. The vulnerability is particularly critical because the service typically runs as root and is accessible over the network, and can be exploited without authentication, especially when combined with the authentication bypass in CVE-2023-28503.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2023-28502) in Rocket Software UniData udadmin_server (Linux, version 8.2.4 build 3001). The exploit abuses the password field in the authentication process, which is copied to a stack buffer without bounds checking, allowing for remote code execution as root. The module supports both direct command execution and staged payload delivery via a command stager. The exploit communicates with the UniRPC service (default endpoint 'udadmin') over TCP port 31438. The code is operational and provides options for version targeting, endpoint selection, and clean process termination. The repository structure is typical for a Metasploit exploit module, with all logic contained in a single Ruby file.
