CWE-120Published: January 26, 2023· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

Several stack-based buffer overflow vulnerabilities exist in the DetranCLI command parsing functionality of Siretta QUARTZ-GOLD G5.0.1.5-210720-141020. A specially-crafted network packet can lead to arbitrary command execution. An attacker can send a sequence of requests to trigger these vulnerabilities.This buffer overflow is in the function that manages the 'gre index <1-8> tunnel A.B.C.D source (A.B.C.D|null) dest A.B.C.D keepalive (on|off) interval (<0-255>|null) retry (<0-255>|null) description (WORD|null)' command template.
