VMware Patches Critical Flaw in Workspace ONE UEM Console

VMware on Thursday announced the release of patches for a critical server-side request forgery (SSRF) vulnerability in Workspace ONE UEM console.

An attacker could exploit the flaw to access sensitive data in the management console, VMware says. Tracked as CVE-2021-22054, the security error carries a CVSS score of 9.1.

To exploit the vulnerability, an attacker needs to have network access to UEM, so they can send unauthenticated requests and trigger the bug.

The vulnerability was reported privately to the cloud computing and virtualization technology company, and both patches and workarounds have been released to address it.

CVE-2021-22054 was fixed with the release of VMware Workspace ONE UEM console versions 21.5.0.37, 21.2.0.27, 20.11.0.40, and 20.0.8.36. VMware Workspace ONE UEM patch 21.9.0.13 and above also address the bug.

VMware also says it has mitigated the issue for VMware-hosted Workspace ONE consoles and notes that some workarounds are available for on-premises installations.

“The issue has been mitigated across all SaaS environments through infrastructure changes which will remain in place until VMware Cloud Operations has deployed the necessary patches,” VMware says.

Organizations that cannot patch their on-premises environments can find available workarounds in a support article. The workaround was designed to block access to a specific endpoint when the request includes a 'url' query parameter, thus removing the possibility of exploitation.
