CVE-2022-23968

https://notcve.org/view.php?id=CVE-2022-23968

Xerox VersaLink devices on specific versions of firmware before 2022-01-26 allow remote attackers to brick the device via a crafted TIFF file in an unauthenticated HTTP POST request. There is a permanent denial of service because image parsing causes a reboot, but image parsing is restarted as soon as the boot process finishes. However, this boot loop can be resolved by a field technician. The TIFF file must have an incomplete Image Directory. Affected firmware versions include xx.42.01 and xx.50.61. • https://neosmart.net/blog/2022/xerox-vulnerability-allows-unauthenticated-network-users-to-remotely-brick-printers https://twitter.com/mqudsi/status/1485756915187695618 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
