CVE-2022-41021Public exploitNetwork attack vector

Authenticated command execution via unbounded CLI formatting

Published Jan 26, 2023 · Updated Nov 4, 2025

Stack buffer overflow in Siretta QUARTZ-GOLD G5.0.1.5-210720-141020 allows remote authenticated users to execute commands. The DetranCLI handler for the vpn l2tp advanced name command with options uses sprintf to place attacker-controlled fields into a 256-byte stack buffer without a length bound. Administrative CLI access is required; successful exploitation executes arbitrary commands and can fully compromise the router.
