CVE-2020-7200 is a critical remote code execution vulnerability in HPE Systems Insight Manager (SIM) version 7.6. The vulnerability resides in the simsearch.war component, specifically in the /simsearch/messagebroker/amfsecure endpoint, which listens on port 50000. The flaw is due to insecure deserialization of AMF (Action Message Format) payloads, which are processed pre-authentication. Attackers can exploit this by sending crafted AMF payloads that trigger a Java deserialization chain, leveraging the presence of outdated CommonsCollections libraries and the org.jgroups.blocks.ReplicatedTree.setState() method, ultimately leading to arbitrary code execution. The vulnerability affects both Windows and Linux installations.

This repository contains a single Metasploit module targeting a remote code execution vulnerability (CVE-2020-7200) in HPE Systems Insight Manager (SIM) version 7.6.x on Windows. The exploit leverages an insecure AMF deserialization process in the '/simsearch/messagebroker/amfsecure' endpoint, allowing an unauthenticated attacker to execute arbitrary commands or PowerShell scripts as the administrative user running the HPE SIM service. The module supports both command and PowerShell payloads, and includes a check method to verify if the target is a vulnerable HPE SIM instance. The exploit is operational and requires the target to be accessible over HTTPS (default port 50000). The repository is structured as a single Ruby file compatible with the Metasploit framework, and is intended for use within that framework.
This repository provides a proof-of-concept exploit for CVE-2020-7200, a remote code execution vulnerability in HPE Systems Insight Manager (SIM) 7.6. The vulnerability is due to unsafe Java deserialization in the simsearch.war component, specifically via the /simsearch/messagebroker/amfsecure endpoint. The README details the affected files and mitigation steps, while the Java source files (Test0.java and Test1.java) demonstrate how to craft and serialize malicious Java objects using Apache Commons Collections gadget chains. Test1.java constructs a payload that, when deserialized by the vulnerable server, executes arbitrary commands (e.g., launching calc.exe). The exploit requires the target server to be running and accessible on port 50000. The repository is structured with utility code (Strings.java) and two main exploit scripts (Test0.java for basic serialization, Test1.java for weaponized command execution).
