VMware Patches Multiple Vulnerabilities in Workspace ONE, Identity and Lifecycle Manager and vRealize (VMSA-2022-0011)

VMware cautions organizations to patch or mitigate several serious vulnerabilities across multiple products.

Update April 18: Updated the Solution section to note that the VMware advisory now indicates that CVE-2022-22960 has been exploited in the wild.

View Change Log

Background

On April 6, VMware published an advisory (VMSA-2022-0011) addressing eight vulnerabilities across a number of VMware products:

CVE Description CVSSv3
CVE-2022-22954 Server-side Template Injection Remote Code Execution Vulnerability 9.8
CVE-2022-22955 OAuth2 ACS Authentication Bypass Vulnerability 9.8
CVE-2022-22956 OAuth2 ACS Authentication Bypass Vulnerability 9.8
CVE-2022-22957 JDBC Injection Remote Code Execution Vulnerability 9.1
CVE-2022-22958 JDBC Injection Remote Code Execution Vulnerability 9.1
CVE-2022-22959 Cross SIte Request Forgery Vulnerability 8.8
CVE-2022-22960 Local Privilege Escalation Vulnerability 7.8
CVE-2022-22961 Information Disclosure Vulnerability 5.3

Affected products include:

All eight vulnerabilities were disclosed to VMware by Steven Seeley, a security researcher with Qihoo 360 Vulnerability Research Institute.

Analysis

CVE-2022-22954 is a server-side template injection vulnerability in the VMware Workspace ONE Access and Identity Manager. This vulnerability was assigned a CVSSv3 score of 9.8. An unauthenticated attacker with network access could exploit this vulnerability by sending a specially crafted request to a vulnerable VMware Workspace ONE or Identity Manager. Successful exploitation could result in remote code execution by exploiting a server-side template injection flaw.

CVE-2022-22955 and CVE-2022-22956 are a pair of authentication bypass vulnerabilities in the OAuth 2.0 Access Control Services (ACS) framework within VMware Workspace ONE. Both of these vulnerabilities were assigned a CVSSv3 score of 9.8. An unauthenticated attacker could send specially crafted requests to vulnerable and exposed OAuth2.0 endpoints in VMware Workspace ONE in order to successfully authenticate to the Workspace ONE instance.

These three vulnerabilities are the only ones patched in this advisory that do not require authentication prior to exploitation. The remaining five do, and as such, have been assigned lower CVSSv3 scores.

Russian state-sponsored actors have targeted VMware Workspace ONE in the past

In December 2020, the National Security Agency revealed that Russian state-sponsored threat actors had exploited CVE-2020-4006, a command injection flaw in the administrative configurator component across a number of VMware products including Workspace ONE Access, Identity Manager, Cloud Foundation and vRealize Suite Lifecycle Manager.

While the vulnerabilities in VMSA-2022-0011 were addressed as part of a coordinated disclosure, attackers do routinely target legacy vulnerabilities.

Proof of concept

At the time this blog post was published, no proof-of-concept (PoC) exploits had been shared for any of the vulnerabilities. Update 4/13: There are now several PoCs for CVE-2022-22954 available on GitHub.

Solution

VMware released patches for the vulnerabilities in the following affected products:

Product/Component Affected Versions
VMware Workspace ONE Access Appliance 21.08.0.1, 21.08.0.0, 20.10.0.1, 20.10.0.0
VMware Identity Manager Appliance 3.3.3, 3.3.4, 3.3.5, 3.3.6
VMware vRealize Automation 7.6

VMware urges organizations to take immediate action

As part of an FAQ document for VMSA-2022-0011, VMware has stressed that these vulnerabilities “should be patched or mitigated immediately” and that the “ramifications” are “serious.” If patching these flaws is not feasible, VMware has also shared workaround instructions as a temporary solution, but states that patching is the only way to remove these flaws entirely

As of April 13, VMware updated its FAQ confirming that in-the-wild exploitation of CVE-2022-22954 has been detected.

As of April 18, the VMSA-2022-0011 advisory has been updated to reflect that CVE-2022-22960 has been exploited in the wild. However, at this time the change only appears in the notes section of the CVE description. VMware has not yet updated the FAQ page that accompanies this advisory.
