Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 1.12% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Unknown Vijeo Designer Basic (V1.1 HotFix 16 and prior) and Vijeo Designer (V6.2 SP9 and prior) 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.

What, why and how

A CWE-798: Use of Hard-coded Credentials vulnerability exists in Vijeo Designer Basic (V1.1 HotFix 16 and prior) and Vijeo Designer (V6.2 SP9 and prior) which could cause unauthorized read and write when downloading and uploading project or firmware into Vijeo Designer Basic and Vijeo Designer.

What

A CWE-798: Use of Hard-coded Credentials vulnerability exists in Vijeo Designer Basic (V1.1 HotFix 16 and prior) and Vijeo Designer (V6.2 SP9 and prior) which could cause unauthorized read and write when downloading and uploading project or firmware into Vijeo Designer Basic and Vijeo Designer.

Why

A credential embedded in the product can be recovered or reused across installations instead of being unique to one deployment.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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
