CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2024-36486 impacting parallels parallels_desktop. Evaluated with CVSS Base Score of 7.8 (HIGH).

Original NVD Description

Source: NIST NVD
A privilege escalation vulnerability exists in the virtual machine archive restoration functionality of Parallels Desktop for Mac version 20.1.1 (55740). When an archived virtual machine is restored, the prl_vmarchiver tool decompresses the file and writes the content back to its original location using root privileges. An attacker can exploit this process by using a hard link to write to an arbitrary file, potentially resulting in privilege escalation.
