CVE-2024-12356 is a critical unauthenticated remote code execution vulnerability affecting BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS). Public descriptions characterize it as a command injection flaw that allows an unauthenticated attacker to inject commands executed as the site user. More detailed technical analysis indicates the vulnerable path is reachable through a WebSocket endpoint in RS and involves improper handling of attacker-controlled input passed through the thin-scc-wrapper path. Specifically, an unquoted attacker-controlled parameter is passed into shell processing in a way that permits argument injection, and successful RCE in tested RS exploit paths depended on chaining this weakness with PostgreSQL issue CVE-2025-1094 to transform escaped input into executable SQL and then invoke operating-system commands via psql meta-command handling. The vulnerability was exploited as a zero-day and is associated with compromises of BeyondTrust infrastructure and downstream customer instances.

This repository contains a single Metasploit module: 'beyondtrust_pra_rs_unauth_rce.rb', which exploits unauthenticated remote code execution vulnerabilities in BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) products (versions 24.3.1 and below) on Linux. The exploit leverages HTTP(S) endpoints exposed by the target, specifically '/get_rdf' and '/download_client_connector', to identify and interact with vulnerable instances. The module supports customizable command execution payloads, including reverse shells, and executes them as the 'site user' on the target system. The exploit can optionally leverage CVE-2024-12356 (argument injection) and CVE-2025-1094 (SQL injection in PostgreSQL code), depending on configuration. The code is weaponized, allowing for easy payload customization and integration into Metasploit workflows. The repository is structured as a single Ruby file, following standard Metasploit module conventions, and is intended for use within the Metasploit framework.
