Denial of Service Vulnerability in Lexmark Printers and MarkNet Devices

CVE-2010-0101

Summary

Multiple Lexmark laser and inkjet printers, along with MarkNet devices, contain an embedded HTTP server that is susceptible to a denial of service attack. Malicious actors can exploit this vulnerability by sending a specially crafted HTTP Authorization header, which may lead to the operating system of the affected device halting unexpectedly. This could compromise the availability of the printer and require a restart to regain functionality. It is crucial for users to ensure their devices are updated with the latest security patches to mitigate potential attacks.
