EcoStruxure EV Charging Expert (formerly known…: Improper Restriction of Rendered UI Layers or Frames

CVE-2022-22807 is a high-severity improper restriction of rendered UI layers or frames vulnerability in EcoStruxure EV Charging Expert (formerly known as EVlink Load Management System): (HMIBSCEA53D1EDB, HMIBSCEA53D1EDS, HMIBSCEA53D1EDM, HMIBSCEA53D1EDL, HMIBSCEA53D1ESS, HMIBSCEA53D1ESM, HMIBSCEA53D1EML) (All Versions prior to SP8 (Version 01) V4.0.0.13), with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. There is no confirmed exploitation so far. EPSS estimates a 0.94% chance of exploitation within 30 days, higher than 61% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Hmibscea53d1edb Firmware to 4.0.0.13 or a later version.
  2. Update Hmibscea53d1eds Firmware to 4.0.0.13 or a later version.
  3. Update Hmibscea53d1edm Firmware to 4.0.0.13 or a later version.
  4. Read the advisory on download.schneider-electric.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  6. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

A CWE-1021 Improper Restriction of Rendered UI Layers or Frames vulnerability exists that could cause unintended modifications of the product settings or user accounts when deceiving the user to use the web interface rendered within iframes. Affected Product: EcoStruxure EV Charging Expert (formerly known as EVlink Load Management System): (HMIBSCEA53D1EDB, HMIBSCEA53D1EDS, HMIBSCEA53D1EDM, HMIBSCEA53D1EDL, HMIBSCEA53D1ESS, HMIBSCEA53D1ESM, HMIBSCEA53D1EML) (All Versions prior to SP8 (Version 01) V4.0.0.13)

The underlying weakness: Improper Restriction of Rendered UI Layers or Frames

The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.

How developers prevent this class of flaw

  • Use the frame-ancestors directive in the Content Security Policy, which is intended to define restrictions when it comes to allowing embedded content.
  • The use of X-Frame-Options (now partially obsolete as of September 2026) allows developers of web content to restrict the usage of their application within the form of overlays, frames, or iFrames. The developer can indicate from which domains can frame the content. The concept of X-Frame-Options is well documented, but implementation of this protection mechanism is in development to cover gaps; often, there is a need for allowing frames from multiple domains.
  • Use a frame-breaker script in each page that should not be framed. This is very helpful for legacy browsers that do not support the X-Frame-Options security feature previously mentioned (which is now partially obsolete).
