CVE-2023-50733Network attack vector

Remote code execution via Web Services SSRF

Published Jan 21, 2025 · Updated Jan 22, 2025

SSRF in affected Lexmark printer firmware allows remote attackers to execute arbitrary code through the Web Services feature. The vulnerable service listens on TCP port 65002, but Lexmark has not disclosed the specific handler or validation failure that permits server-side requests. No authentication or user interaction is required, and successful exploitation provides code execution on the printer.
