CVE-2022-31689Network attack vector

Session hijacking via reusable session token

Published Nov 9, 2022 · Updated May 1, 2025

Session fixation in Omnissa Workspace ONE Assist before 22.10 allows remote attackers to authenticate with an obtained valid session token. The server-side session mechanism accepts that existing token as authentication; VMware has not disclosed the affected endpoint or precise token-lifecycle error. Exploitation requires prior acquisition of a valid token and yields access in its associated application context; broader privilege is not documented.
