Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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 'firmwall domain WORD description (WORD|null)' command template.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Stack-based buffer overflow in Siretta QUARTZ-GOLD router's DetranCLI command parsing for the 'firmwall domain WORD description' template. Improper bounds checking on user-supplied input allows overflowing a stack-allocated buffer, enabling arbitrary command execution via carefully crafted network packets.

MitigationApply vendor firmware patch when available. Until then, restrict network access to the administrative interface to trusted IPs only to reduce attack surface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the router's web interface or CLI and locate the model identification. Look for 'Quartz Gold' or 'QUARTZ-GOLD' in the device information page or banner.
    Affected if The device is not a Siretta QUARTZ-GOLD router.
  2. Determine the installed firmware version
    Access the router's web interface, typically under 'System' or 'Administration' > 'Firmware/Upgrade' section. Alternatively, check the CLI prompt or banner upon login for a version string.
    Affected if The firmware version is g5.0.1.5-210720-141010 (the exact version string '= g5.0.1.5-210720-141020' indicates the affected build). Compare your installed version to this specific build to confirm a match.
  3. Verify DetranCLI access
    Attempt to access the DetranCLI interface via telnet or SSH if available on the device. Look for a command prompt that accepts 'firmwall domain' type commands.
    Affected if The DetranCLI interface is accessible and the 'firmwall domain WORD description' command template is present.
  4. Check administrative interface network exposure
    Review the router's firewall or access control settings. Determine if the web/CLI administrative interface is bound to WAN-facing interfaces or exposed to untrusted networks.
    Affected if The administrative interface (HTTP/HTTPS/Telnet/SSH) is accessible from WAN or untrusted networks.
  5. Inspect for suspicious process or service behavior
    If CLI access is available, run commands to list running processes or check for unexpected listening services on the router that may indicate exploitation attempts.
    Affected if Unexpected processes are running or unusual services are listening on the device.

The environment is affected if the device is a Siretta QUARTZ-GOLD running firmware version g5.0.1.5-210720-141020, the DetranCLI is accessible, and the administrative interface is exposed to untrusted networks.
