Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.42% 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 Unknown ZigBee Installation Toolkit (Versions prior to 1.0.1) 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-426: Untrusted Search Path vulnerability exists in ZigBee Installation Kit (Versions prior to 1.0.1), which could cause execution of malicious code when a malicious file is put in the search path.

What

A CWE-426: Untrusted Search Path vulnerability exists in ZigBee Installation Kit (Versions prior to 1.0.1), which could cause execution of malicious code when a malicious file is put in the search path.

Why

The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control.

How

An attacker operating through local access may attempt exploitation without authentication after a user interaction. 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

CWE-426 ↗

CWE-426: Untrusted Search Path. The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control.
