The embedded HTTP server in multiple Lexmark laser and inkjet printers and MarkNet devices, including X94x, W840, T656, N4000, E462, C935dn, 25xxN, and other models, allows remote attackers to cause a denial of service (operating system halt) via a malformed HTTP Authorization header.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
