CVE-2022-23968 is a high-severity vulnerability affecting xerox versalink_firmware. It was published on January 26, 2022 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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. NOTE: the 2022-01-24 NeoSmart article included "believed to affect all previous and later versions as of the date of this posting" but a 2022-01-26 vendor statement reports "the latest versions of firmware are not vulnerable to this issue."
Remediation
Check the references section for vendor advisories and patches from xerox. Update versalink_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
