Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.22% 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 Schneider Electric EcoStruxure™ IT Data Center Expert 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 30 daysRemediation target: Within 180 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.

01

What, why and how

A CWE-331: Insufficient Entropy vulnerability exists that could cause root password discovery when the password generation algorithm is reverse engineered with access to installation or upgrade artifacts.

What

A CWE-331: Insufficient Entropy vulnerability exists that could cause root password discovery when the password generation algorithm is reverse engineered with access to installation or upgrade artifacts.

Why

The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

How

02

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
an adjacent network → Insufficient Entropy → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Adjacent
Privileges required
None: unauthenticated exploitation is possible
User interaction

High: exploitation depends on specific conditions

Official advisory ↗
NCSC-NL · Dutch · NCSC-2025-0221Kwetsbaarheden verholpen in Schneider Electric EcoStruxture IT Datacenter Expert

De kwetsbaarheden omvatten onder andere onvoldoende controle over speciale elementen in OS-commando's, wat kan leiden tot ongeauthenticeerde externe code-executie. Daarnaast is er een probleem met onvoldoende entropie in wachtwoordgeneratie-algoritmen, wat kan resulteren in het ontdekken van rootwachtwoorden. Verder is er een kwetsbaarheid gerelateerd aan onjuiste controle van codegeneratie, wat kan leiden tot externe opdrachtuitvoering via hostname-invoer. Ook is er een Server-Side Request Forgery (SSRF) kwetsbaarheid die ongeauthenticeerde externe code-executie mogelijk maakt door manipulatie van verborgen URL's. Bovendien is er een probleem met onjuiste privilegebeheer, wat kan leiden tot privilege-escalatie. Tot slot kan er ongeautoriseerde bestandstoegang plaatsvinden door het misbruiken van SOAP API-aanroepen en XML externe entiteiten injectie.
