CVE-2022-41991Network attack vector

Unauthenticated service crash via undersized entry length

Published Jan 26, 2023 · Updated Mar 5, 2025

Heap-based buffer overflow in Siretta QUARTZ-GOLD G5.0.1.5-210720-141020 allows remote attackers to crash the M2M service via UDP. The DELETE_FILE handler allocates a command buffer from an attacker-supplied entry length, then sprintf copies null-terminated entry data beyond that allocation. The M2M feature must be enabled; no authentication or user interaction is reported, and Talos demonstrated a SIGSEGV in the m2m process.
