CVE-2020-28653 is an unauthenticated remote code execution vulnerability in Zoho ManageEngine OpManager affecting Stable builds before 125203 and Released builds before 125233. The flaw is in the Smart Update Manager (SUM) servlet. Based on the provided advisory, a remote attacker can reach the vulnerable servlet and trigger arbitrary code execution on the OpManager host without authentication, resulting in compromise of the underlying system.

This repository contains a single Metasploit module targeting a Java deserialization vulnerability in ManageEngine OpManager (CVE-2020-28653 and CVE-2021-3287). The exploit leverages unauthenticated HTTP POST requests to specific endpoints ('/servlets/com.adventnet.tools.sum.transport.SUMHandShakeServlet' and '/servlets/com.adventnet.tools.sum.transport.SUMCommunicationServlet') to deliver malicious Java serialized objects, resulting in remote code execution as SYSTEM/root. The module supports multiple payload types and platforms (Windows, Linux, Unix, Python), and can deliver staged payloads such as Meterpreter or reverse shells. The exploit is weaponized, requiring only the target's network accessibility and no authentication. The code is structured as a standard Metasploit module, with clear separation of target platforms, payload delivery, and vulnerability checks.
This repository contains a Python exploit for CVE-2020-28653, targeting ManageEngine SupportCenter Plus versions from 2016 to 2020 (before patch). The exploit script (exploit.py) interacts with the target web application by sending crafted HTTP POST requests to specific servlet endpoints. It first checks the version of the target, then uses binary payloads (int.bin and gadget-<version>.bin, not included in the repo) to trigger and exploit the vulnerability. The exploit allows the attacker to execute arbitrary system commands on the target server interactively, with commands sent via a custom HTTP header. The README provides basic usage instructions. The main fingerprintable endpoints are the two servlet paths used for exploitation. The repository is operational, requiring some external files to function fully.
