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
If an attacker has access to the firmware from the VGo Robot (Versions 3.0.3.52164 and 3.0.3.53662. Prior versions may also be affected) they may be able to extract credentials.

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

This vulnerability allows an attacker with access to VGo Robot firmware (versions 3.0.3.52164 and 3.0.3.53662) to extract stored credentials from the firmware image. The credentials are apparently stored in plaintext or with weak protection within the firmware filesystem, enabling unauthorized access to the robot's management interfaces or network services.

MitigationOrganizations should update to a patched firmware version if available, rotate any credentials that may have been exposed, and implement firmware integrity verification to detect tampering. If no patched firmware exists, network segmentation and access controls should be applied to limit exposure of the robot's management interfaces.

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 VGo robot firmware version
    Access the robot's management interface or use the command line tool provided by Vecna to query the current firmware version. This is typically found in the system information or about section of the robot's admin panel, or via a command like 'show version' or 'firmware-info' through the robot's CLI.
    Affected if The firmware version is 3.0.3.52164 or 3.0.3.53662.
  2. Confirm the exact firmware build number
    Retrieve the full firmware build identifier from the robot. Ensure you capture the complete version string including any build numbers or revision identifiers that accompany the main version number.
    Affected if The build matches exactly 3.0.3.52164 or 3.0.3.53662.
  3. Determine if firmware image or filesystem is accessible
    Check whether the robot's firmware image, filesystem dumps, or backup files are stored in locations accessible to unauthorized users. This includes checking network shares, USB ports, debug interfaces, or any place where firmware backups might be stored.
    Affected if Firmware images or filesystem extracts are accessible without proper access controls, allowing an attacker to obtain a copy for credential extraction.
  4. Inspect firmware for credential storage patterns
    If you have access to a firmware image or filesystem dump, examine configuration files, shadow files, or credential storage locations for plaintext or weakly protected passwords. Look for patterns indicating credentials stored without encryption.
    Affected if Credentials are stored in plaintext or with weak protection (e.g., base64 encoding, simple XOR, or unencrypted) within the firmware filesystem.
  5. Review access to robot management interfaces
    Check whether the robot's management interfaces (web UI, telnet, SSH) are exposed to untrusted networks or lack strong authentication. Assess if an attacker could easily reach these interfaces.
    Affected if Management interfaces are reachable by unauthorized users, enabling them to obtain firmware images or attempt credential-based access.

A VGo robot is affected if it runs firmware version 3.0.3.52164 or 3.0.3.53662 and an attacker can access the firmware image or management interfaces to extract weakly protected credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 3.0.3.52164
Interim mitigation

Organizations should update to a patched firmware version if available, rotate any credentials that may have been exposed, and implement firmware integrity verification to detect tampering. If no patched firmware exists, network segmentation and access controls should be applied to limit exposure of the robot's management interfaces.
