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 OS command injection vulnerability exists in XWEB Pro version 1.12.1 and prior, enabling an authenticated attacker to achieve remote code execution on the system by injecting malicious input into the Wi-Fi SSID and/or password fields can lead to remote code execution when the configuration is processed.

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

OS command injection vulnerability in XWEB Pro version 1.12.1 and prior allows authenticated attackers to achieve remote code execution by injecting malicious input into Wi-Fi SSID and/or password fields. The injected payload is processed through system commands without proper sanitization, enabling arbitrary command execution on the host system.

MitigationUpgrade to a patched version of XWEB Pro when available. In the interim, implement strict input validation and sanitization on Wi-Fi configuration fields, and refactor code to use parameterized commands or avoid shell execution entirely.

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 Xweb Pro firmware version
    Access the device's web management interface and navigate to System Information or About page to view the firmware version. Alternatively, check the device's administration console or look for version information in the HTTP headers or login page source.
    Affected if The firmware version is 1.12.1 or prior on Copeland Xweb 300d Pro, Xweb 500d Pro, or Xweb 500b Pro.
  2. Confirm web interface is accessible
    Attempt to reach the device's web interface via HTTP/HTTPS on the expected management port (typically 80/443 or a custom port). Verify the page loads and presents a login prompt.
    Affected if The web management interface is exposed and accessible.
  3. Check if Wi-Fi configuration module is available
    Log into the web interface and navigate to Network Settings, Wi-Fi Configuration, or Wireless Setup sections. Look for SSID and password fields.
    Affected if Wi-Fi configuration fields (SSID and/or password) are present and can be modified.
  4. Verify authentication is required
    Confirm the web interface requires valid credentials to access. Try accessing Wi-Fi configuration pages without logging in to verify authentication is enforced.
    Affected if The interface accepts authentication but may have weak or default credentials, allowing an attacker to authenticate.
  5. Inspect for signs of exploitation
    Review system logs for unexpected commands, shell executions, or unusual network connections. Check for new or unexpected processes on the host system. Review Wi-Fi configuration entries for suspicious characters in SSID or password fields.
    Affected if Logs show execution of unexpected system commands, or Wi-Fi fields contain suspicious payloads with special characters that may indicate prior exploitation.

You are affected if your Copeland Xweb Pro device runs firmware version 1.12.1 or prior, has its web interface accessible, and includes Wi-Fi configuration functionality that accepts user input without sanitization.
