CVE-2021-31427

Name of the Vulnerable Software and Affected Versions Parallels Desktop version 15.1.5-47309

Description This issue allows local attackers to disclose sensitive information on affected installations. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this issue. The specific flaw exists within the Open Tools Gate component, resulting from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other issues to escalate privileges and execute arbitrary code in the context of the hypervisor.

Recommendations For Parallels Desktop version 15.1.5-47309, consider disabling the Open Tools Gate component as a temporary workaround until a patch is available. Restrict access to the component to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
