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 'ipv6 static dns WORD WORD WORD' 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 · moderate confidence

Stack-based buffer overflow vulnerability in Siretta QUARTZ-GOLD router's DetranCLI command parsing. The function handling the 'ipv6 static dns WORD WORD WORD' command template lacks proper bounds checking, allowing an attacker to overflow the stack buffer with specially-crafted network packets and achieve arbitrary command execution with elevated privileges.

MitigationApply vendor firmware patch if available; otherwise, restrict network access to the router's management interface and disable or firewall the affected CLI functionality to prevent unauthenticated attackers from sending malicious commands.

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 router model
    Access the router's web interface or CLI and confirm the device is a Siretta Quartz Gold. Check the device label or system information page for the model name.
    Affected if The device is not a Siretta Quartz Gold model, then this CVE does not apply.
  2. Check the installed firmware version
    Access the router's web interface (typically at 192.168.1.1) and navigate to the Status or System Information page to view the firmware version. Compare it to the affected version g5.0.1.5-210720-141020.
    Affected if The firmware version exactly matches g5.0.1.5-210720-141020, indicating the router is running the affected version.
  3. Verify DetranCLI service accessibility
    Determine if the DetranCLI command-line interface is exposed to the network. This may be accessible via telnet, SSH, or a specific management port on the router. Check the router's service configuration or firewall rules.
    Affected if DetranCLI is accessible remotely over the network without authentication or from an untrusted network segment.
  4. Confirm ipv6 static dns command availability
    Log into DetranCLI (via console, telnet, or SSH) and check if the 'ipv6 static dns' command is available. Attempt to access help for ipv6-related commands using '?' or 'help'.
    Affected if The 'ipv6 static dns WORD WORD WORD' command template is functional and accessible through DetranCLI.

A user is affected if they are running Siretta Quartz Gold firmware version g5.0.1.5-210720-141020 AND the DetranCLI service with the ipv6 static dns command is accessible to an attacker on the network.
