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 'no firmwall srcmac (WORD|null) srcip (A.B.C.D|null) dstip (A.B.C.D|null) protocol (none|tcp|udp|icmp) srcport (<1-65535>|null) dstport (<1-65535>|null) policy (drop|accept) description (WORD|null)' command template.
