The vendor explicitly identifies these products as affected by this CVE.

  • Schneider Electric EVlink Home Smart version v2.0.4.1.2_131
  • Schneider Electric EVlink Home Smart version v2.0.3.8.2_128
Summary
CWE-668: Exposure of the Resource Wrong Sphere vulnerability exists that exposes a SSH interface over the product network interface. This does not allow to directly exploit the product or make any unintended operation as the SSH interface access is protected by an authentication mechanism. Impacts are limited to port scanning and fingerprinting activities as well as attempts to perform a potential denial of service attack on the exposed SSH interface.
Remediation
Version 2.0.5.0.0_134 of EVlink Home Smart includes a fix for this vulnerability that has been automatically deployed since April 19th to all charging stations connected to the Wiser application. Make sure the charging station is connected to the Wiser application to ensure the new version can be downloaded and installed. The installed firmware version can be verified through Wiser application (refer to the settings page for the charging station).

What, why and how

CWE-668: Exposure of the Resource Wrong Sphere vulnerability exists that exposes a SSH interface over the product network interface. This does not allow to directly exploit the product or make any unintended operation as the SSH interface access is protected by an authentication mechanism. Impacts are limited to port scanning and fingerprinting activities as well as attempts to perform a potential denial of service attack on the exposed SSH interface.

What

CWE-668: Exposure of the Resource Wrong Sphere vulnerability exists that exposes a SSH interface over the product network interface. This does not allow to directly exploit the product or make any unintended operation as the SSH interface access is protected by an authentication mechanism. Impacts are limited to port scanning and fingerprinting activities as well as attempts to perform a potential denial of service attack on the exposed SSH interface.

Why

The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
