CVE-2022-23968Public exploitNetwork attack vector

Persistent reboot loop via incomplete TIFF directory

Published Jan 26, 2022 · Updated Aug 3, 2024

Denial of service in Xerox VersaLink firmware before xx.61.23 allows remote attackers to trigger a persistent reboot loop via HTTP. The TIFF handler panics while parsing an incomplete Image Directory, and the queue manager retries the persisted job after every reboot. Unauthenticated print-job submission is enabled by default, and the device remains unusable until the persisted job is cleared.
