Omnissa Workspace ONE UEM Server-Side Request Forgery
CVE-2021-22054 is a server-side request forgery (SSRF) vulnerability in VMware Workspace ONE UEM console, now Omnissa Workspace ONE UEM. Affected versions are 20.0.8 prior to 20.0.8.37, 20.11.0 prior to 20.11.0.40, 21.2.0 prior to 21.2.0.27, and 21.5.0 prior to 21.5.0.37. The issue allows a malicious actor with network access to the UEM environment to cause the server to send attacker-controlled requests without authentication, which can expose sensitive information.

This repository provides a Python script (ssrf.py) that generates and optionally sends SSRF (Server-Side Request Forgery) payloads targeting VMware Workspace ONE UEM instances vulnerable to CVE-2021-22054. The exploit leverages the /AirWatch/BlobHandler.ashx?Url= and /Catalog/BlobHandler.ashx?Url= endpoints, which are susceptible to SSRF when provided with a specially crafted, AES-encrypted URL parameter. The script includes a custom encryption routine to match the application's expected payload format. Users can generate payloads for proof-of-concept or send them directly to a target, with support for custom HTTP methods, headers, and proxies. The repository includes a README with usage examples and references, a requirements.txt for dependencies (pycryptodome, requests), and the main exploit script. The exploit is a proof-of-concept and does not include post-exploitation features.
