Vulnerability from github – Published: 2022-01-27 00:01 – Updated: 2022-02-04 00:00

Details

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."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
