CVE-2021-33020Network attack vector

Protected-data exposure via expired cryptographic material

Published Apr 1, 2022 · Updated Apr 16, 2025

Use of expired cryptographic material in Philips Vue PACS 12.2.x.x and earlier allows remote attackers to expose protected data. The software continues using a cryptographic key or password after expiration, extending the cracking window, but Philips has not publicly identified the credential or operation. Network access without authentication is the published gate, and the same condition affects Vue MyVue and Vue Speech 12.2.x.x and earlier and Vue Motion 12.2.1.5 and earlier.
