Omnissa Workspace ONE UEM Server-Side Request Forgery

IdentifiersCVE-2021-22054CWE-918· Server-Side Request Forgery (SSRF)

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.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow an unauthenticated attacker with network access to the UEM instance to abuse the server as a proxy for outbound requests and obtain sensitive information. Depending on reachable internal or trusted resources, this may enable access to data not otherwise exposed to the attacker.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict network access to the UEM console to only trusted administrative networks, limit the system’s ability to reach internal-only services and sensitive metadata endpoints, and monitor for anomalous outbound requests originating from the UEM server. These are compensating controls only; the content does not provide a vendor-endorsed mitigation that replaces patching.

Remediation

Patch, then assume compromise.

Upgrade VMware/Omnissa Workspace ONE UEM console to a fixed release: 20.0.8.37 or later, 20.11.0.40 or later, 21.2.0.27 or later, or 21.5.0.37 or later, as applicable. Apply the vendor security advisory guidance and prioritize patching because the vulnerability has been listed by CISA as known exploited.

CVE-2021-22054MaturityPoCVerified exploit

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.
