CVE-2010-0101: The embedded HTTP server in multiple Lexmark laser and inkjet printers and MarkNet devices, including X94x,...

Security readout for executives and security teams

CVE-2010-0101 is a denial-of-service issue in embedded HTTP servers on multiple Lexmark printers and MarkNet devices. A malformed HTTP Authorization header can make the device halt. This is primarily an availability risk: printing, scanning, or network print services may stop until the device is recovered. Organizations are most exposed when affected Lexmark or MarkNet device web interfaces are reachable from user networks, guest networks, or the internet. Exposure is less likely where printer management HTTP is isolated to trusted administration networks. Treat this as a targeted availability issue for print infrastructure. Prioritize exposed or business-critical printers, especially legacy models in shared offices, operations areas, or customer-facing environments. Mitigation focus: Review Lexmark advisory TE87 and current vendor guidance for affected models.; Inventory Lexmark printers and MarkNet devices, including legacy or unsupported units.; Restrict printer web management access to trusted administrative networks only..
