CVE-2020-8968

Local password disclosure via profile-file upload

Published Dec 17, 2021 · Updated Sep 17, 2024

Credential disclosure in Parallels Client 15.5 through 17 allows local users to recover a stored profile password in clear text. The profile-file upload handler decrypts a previously stored RAS profile and exposes its protected password instead of keeping the credential encrypted. Local low-privilege access is required, and the bounded consequence is disclosure of the affected user's profile credential.
