Frequently asked questions

What types of VMware Workspace ONE UEM console versions are affected by CVE-2021-22054?

CVE-2021-22054 affects multiple versions of VMware Workspace ONE UEM console, including versions 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.

What is the weakness class associated with CVE-2021-22054, and how does it enable exploitation?

The weakness class for CVE-2021-22054 is CWE-918, which describes Server-Side Request Forgery (SSRF). This allows a malicious actor to send requests without authentication, potentially leading to unauthorized access to sensitive information by making the UEM system access resources on the actor's behalf.

How can an attacker exploit the server-side request forgery vulnerability in VMware Workspace ONE UEM console?

An attacker with network access to the UEM system can exploit this vulnerability by sending unauthenticated requests. This allows them to access sensitive information that the UEM system has permission to access, without needing any specific privileges on the console itself.

Why is CVE-2021-22054 considered a relevant threat, particularly for internet-facing systems?

VMware Workspace ONE UEM console is often exposed to the internet to facilitate remote device management. The SSRF vulnerability (CVE-2021-22054) allows unauthenticated, network-accessible attackers to compromise sensitive data, making it a significant threat for organizations using this platform externally. The CISA has also listed this vulnerability on its Known Exploited Vulnerabilities Catalog.

What practical steps should organizations take to respond to the VMware Workspace ONE UEM console vulnerability?

Organizations should prioritize identifying all affected Workspace ONE UEM assets. They should then take steps to reduce or isolate the risk, such as applying vendor-provided patches or mitigations. After fixing the vulnerability, it's crucial to verify the remediation and continuously monitor the systems to prevent future exploitation.
