Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.31% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs ABB ABB Ability Edgenius and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

2 known affected

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

  • ABB Ability Edgenius 3.2.0.0
  • ABB Ability Edgenius 3.2.1.1
Summary
The Edgenius Management Portal in the affected product versions contains a vulnerability that allows authentication to be bypassed. An attacker could exploit the vulnerability by sending a specially craft-ed message to the system node allowing the attacker to install and run arbitrary code, uninstall in-stalled applications and modify the configuration of installed applications.
Remediation
ABB has prepared an update to fix this vulnerability included in the latest Roll-Up, ABB Ability Edgenius version 3.2.2.0. ABB advises customers to upgrade as soon as possible. Until the upgrade is applied, ABB advises customers to disable the Edgenius Management Portal to mitigate the vulnerability.

What, why and how

Authentication Bypass Using an Alternate Path or Channel vulnerability in ABB ABB Ability Edgenius.This issue affects ABB Ability Edgenius: 3.2.0.0, 3.2.1.1.

What

Authentication Bypass Using an Alternate Path or Channel vulnerability in ABB ABB Ability Edgenius.This issue affects ABB Ability Edgenius: 3.2.0.0, 3.2.1.1.

Why

The product requires authentication, but the product has an alternate path or channel that does not require authentication.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may bypass an access boundary or take over an account.

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
