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
An issue in V-SOL G/EPON ONU HG323AC-B with firmware version V2.0.08-210715 allows an attacker to execute arbtirary code and obtain sensitive information via crafted POST request to /boaform/getASPdata/formFirewall, /boaform/getASPdata/formAcc.

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

The V-SOL HG323AC-B router firmware V2.0.08-210715 contains a command injection vulnerability in its web interface. Specifically, crafted POST requests to the /boaform/getASPdata/formFirewall and /boaform/getASPdata/formAcc endpoints allow unauthenticated attackers to execute arbitrary code on the device and extract sensitive information.

MitigationUpdate to a patched firmware version if available from V-SOL; otherwise, isolate the device behind a firewall or restrict access to the web management interface to trusted networks only.

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 web interface and check the system status or device info page, or inspect the device label for model HG323AC-B
    Affected if Device model is V-SOL HG323AC-B
  2. Check the firmware version
    Log into the router web interface and navigate to the firmware/version information page, or use a firmware extraction tool if you have a firmware file
    Affected if Firmware version is V2.0.08-210715 or earlier
  3. Verify web management interface accessibility
    Attempt to access the router web interface (HTTP/HTTPS on common ports like 80, 443, 8080) from an untrusted network perspective
    Affected if The web management interface is exposed to untrusted or public networks without network segmentation
  4. Confirm the vulnerable endpoints respond
    Send a GET request to /boaform/getASPdata/formFirewall and /boaform/getASPdata/formAcc and verify they return a valid HTTP response
    Affected if These endpoints are accessible and return HTTP 200 responses, indicating the vulnerable web application is running

You are affected if you have a V-SOL HG323AC-B router running firmware V2.0.08-210715 (or earlier) with its web interface accessible to untrusted networks, as the command injection requires no authentication.
