CVE-2021-22054 is a pre-authentication server-side request forgery vulnerability in VMware Workspace ONE UEM, now Omnissa Workspace ONE UEM. Affected BlobHandler functionality decrypts an attacker-controlled URL parameter and proxies the resulting request from the UEM server. Hardcoded default encryption material associated with the accepted key version permits an unauthenticated attacker to construct URL values accepted by the handler. The proxy supports attacker-controlled HTTP methods and request bodies, enabling requests to arbitrary destinations reachable by the UEM server.

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.

A pre-authentication server-side request forgery vulnerability in VMware Workspace ONE UEM (formerly AirWatch). Hardcoded encryption parameters in the Catalog and AirWatch Console BlobHandler.ashx endpoint let an unauthenticated attacker cause the UEM server to issue arbitrary HTTP requests, including to internal hosts and cloud metadata services, with arbitrary methods and request bodies.
A pre-authentication server-side request forgery (SSRF) vulnerability in VMware Workspace ONE UEM (formerly AirWatch). The affected BlobHandler.ashx endpoints decrypt attacker-controlled URL data using a hard-coded default key and proxy requests to arbitrary destinations, supporting arbitrary HTTP methods and request bodies. This could expose internal services and, for AWS-hosted deployments, instance metadata and potentially high-privilege IAM credentials.
A pre-authentication server-side request forgery vulnerability in VMware Workspace ONE UEM/AirWatch BlobHandler.ashx proxy functionality. Attackers could encrypt attacker-controlled URLs using a hardcoded default master key (key version kv0) and cause the UEM server to issue arbitrary HTTP requests, potentially reaching internal services or cloud-instance metadata endpoints. The issue affected both on-premises and SaaS deployments according to the content.
