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
A CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability exists that could cause a web session compromise when an attacker injects and then executes arbitrary malicious JavaScript code inside the target browser. Affected Product: spaceLYnk (V2.6.2 and prior), Wiser for KNX (formerly homeLYnk) (V2.6.2 and prior), fellerLYnk (V2.6.2 and prior)

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
How this class of weakness works · CWE-79

Untrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

Recommended fix Moderate confidence

Firmware version greater than 2.6.2 (e.g., 2.6.3 or later stable release)

  1. 1. Identify the current firmware version of the affected device (spaceLYnk, Wiser for KNX, or fellerLYnk) via the device's web interface or documentation.
  2. 2. Navigate to the Schneider Electric download portal at https://download.schneider-electric.com/ and locate the firmware update for your specific device.
  3. 3. Download the firmware version newer than 2.6.2 (ensure the version is specifically beyond the vulnerable 2.6.2 release).
  4. 4. Review the firmware release notes to confirm the security update addressing CVE-2022-22812 is included.
  5. 5. Create a backup of the current device configuration before performing the firmware update.
  6. 6. Upload and install the new firmware version following the manufacturer's documented upgrade procedure.
  7. 7. After installation, verify the device is operational and confirm the new firmware version is correctly installed.
  8. 8. Test the web interface functionality to ensure the XSS vulnerability has been remediated.
Caveat Review release notes for any configuration or feature changes between versions; ensure compatibility with connected systems before upgrading
