Multiple Vulnerabilities in VMware vRealize Operations Manager Could Allow for Remote Code Execution






Multiple vulnerabilities have been discovered in VMware vRealize Operations Manager, which could result in remote code execution. VMware vRealize Operations Manager is an IT management platform which enables visibility, optimization and management of an organization’s physical, virtual and cloud infrastructure. This software comes within an API which enables developers to build vRealize Operations Manager clients to communicate with the server over HTTP. Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code in context of the user running the application.


These vulnerabilities were reported by Egor Dimitrenko of Positive Technologies which have showcased a successful exploitation attempt utilizing an unreleased proof of concept.


  • vRealize Operations Manager Versions 7.5.0, 8.0.0, 8.0.1, 8.1.0, 8.1.1, 8.2.0, 8.3.0

Multiple vulnerabilities have been discovered in VMware vRealize Operations Manager, which could result in remote code execution. Details of these vulnerabilities are as follows:

  • A server side request forgery vulnerability in vRealize Operations Manager API which enables a malicious attacker to obtain administrative credentials. (CVE-2021-21975)
  • An arbitrary write vulnerability in vRealize Operations Manager API which enable file writes to arbitrary locations within the underlying operating systems. (CVE-2021-21983)

Chaining together both vulnerabilities enables a malicious actor to perform remote code execution in the context of the logged-on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. A pre-requisite of exploiting these vulnerabilities is that the malicious actor must have network access to the vRealize Operations Manager API.


We recommend the following actions be taken:

  • Apply appropriate updates provided or workarounds mentioned by VMware to vulnerable systems immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
  • Apply the Principle of Least Privilege to all systems and services.
