Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.11% 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 AVEVA Pipeline Integrity Monitor 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: As exposure requiresRemediation target: Within 365 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.

No EUVD known-exploited evidence

The vulnerability, if exploited, could allow a miscreant with read access to PIMBoards project files to reverse engineer PIMBoards users’ app-native passwords through computational brute-forcing of weak hashes, potentially allowing elevation to a PIMBoards administrator user.

01

What, why and how

The vulnerability, if exploited, could allow a miscreant with read access to PIMBoards project files to reverse engineer PIMBoards users’ app-native passwords through computational brute-forcing of weak hashes, potentially allowing elevation to a PIMBoards administrator user.

What

The vulnerability, if exploited, could allow a miscreant with read access to PIMBoards project files to reverse engineer PIMBoards users’ app-native passwords through computational brute-forcing of weak hashes, potentially allowing elevation to a PIMBoards administrator user.

Why

The product uses a broken or risky cryptographic algorithm or protocol.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

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.
