CVE-2024-54189 — A privilege escalation vulnerability exists in the Snapshot functionality of Parallels Desktop for Mac version 20.1.1 (build 55740)

High CVSS 7.8

A privilege escalation vulnerability exists in the Snapshot functionality of Parallels Desktop for Mac version 20.1.1 (build 55740). When a snapshot of a virtual machine is taken, a root service writes to a file owned by a normal user. By using a hard link, an attacker can write to an arbitrary file, potentially leading to privilege escalation.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
