Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.60% 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 PowerLogic ION7400, ION7650, ION83xx/84xx/85xx/8600, ION8650, ION8800, ION9000 and PM800 (see notification for affected versions) 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-319: Cleartext transmission of sensitive information vulnerability exists in PowerLogic ION7400, ION7650, ION83xx/84xx/85xx/8600, ION8650, ION8800, ION9000 and PM800 (see notification for affected versions), that could cause disclosure of user credentials when a malicious actor intercepts HTTP network traffic between a user and the device.

A CWE-319: Cleartext transmission of sensitive information vulnerability exists in PowerLogic ION7400, ION7650, ION83xx/84xx/85xx/8600, ION8650, ION8800, ION9000 and PM800 (see notification for affected versions), that could cause disclosure of user credentials when a malicious actor intercepts HTTP network traffic between a user and the device.

Why

The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may obtain information outside the intended access boundary.

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
