CVE-2016-1543 is an authorization bypass vulnerability in the RSCD agent component of BMC BladeLogic Server Automation (BSA) versions 8.2.x through 8.7.x on Linux and UNIX. The RSCD agent, which listens on port 4750 and communicates using proprietary and XMLRPC protocols over TLS 1.0, fails to properly enforce authentication and authorization checks. Specifically, after an authorization failure, the agent continues to process action packets sent to the xmlrpc interface, allowing remote attackers to bypass authorization and reset arbitrary user passwords, including root, without valid credentials. The flaw is due to improper handling of failed authorization states, enabling attackers to impersonate an Application Server and send unauthorized commands to the agent.

This repository contains a single Metasploit module targeting the BMC Server Automation RSCD agent. The exploit leverages weak access control in the RSCD agent, allowing unauthenticated remote command execution (RCE) on both Windows and Unix/Linux platforms. The module communicates with the RSCD agent over TCP port 4750, sending specially crafted packets to execute arbitrary OS commands. It supports both staged payloads (using VBS for Windows and echo for Unix/Linux) and direct command execution, making it suitable for a variety of post-exploitation scenarios. The exploit is operational and can be used to gain remote access or execute arbitrary code on vulnerable BMC RSCD agents. The module references CVE-2016-1542 and CVE-2016-1543, and includes detection logic to verify if the target is running a vulnerable RSCD agent. The code is written in Ruby and is structured as a standard Metasploit exploit module.
This repository contains four Python scripts targeting vulnerabilities in the BMC BladeLogic RSCD agent (CVE-2016-1542, CVE-2016-1543, CVE-2016-5063) on both Linux and Windows platforms. The scripts are: - BMC_changePwd.py: Exploits the agent to change the password of an arbitrary user without authorization by sending crafted XMLRPC requests over a TLS-wrapped socket. - BMC_getUsers.py: Enumerates system users (both Linux and Windows) by querying the agent via XMLRPC, parsing the returned XML data. - BMC_rexec.py: Achieves remote code execution by sending arbitrary commands to the agent using XMLRPC. This is the most critical exploit, allowing attackers to run any command on the target system. - BMC_winUsers.py: Specifically targets Windows agents to enumerate user accounts and gather system information. All scripts use Python and require the attacker to specify the target host and (optionally) port. The default port is 4750, which is the standard for the RSCD agent. The exploits work by establishing a TLS connection, then sending HTTP/XMLRPC requests to the '/xmlrpc' endpoint. The README provides context, references, and credits, and confirms the scripts have been published on Exploit-DB. The repository is operational in maturity, providing working exploit code for remote code execution, password changes, and user enumeration against vulnerable BMC BladeLogic RSCD agents.
