Potential internet exposure

Potential exposure only — not proof of vulnerability.Shodan results indicate potentially internet-exposed products, not confirmed vulnerable systems. They do not confirm that any returned system is vulnerable to CVE-2026-40385.

Product-level CPE searches intentionally omit version fields and NVD version-range or configuration certainty. Verify the exact product version and configuration independently.

Sign-in required. Shodan requires you to sign in to run these filter searches.

How this vector reads

CVSS 3.1 base metrics decoded below. This explanation does not recalculate or change the NVD score.

Attack Vector (AV): Local. The attacker needs local access to the vulnerable system.
Attack Complexity (AC): High. Successful exploitation depends on conditions outside the attacker's control.
Privileges Required (PR): None. The attacker needs no privileges on the vulnerable system.
User Interaction (UI): None. Exploitation does not require another user to act.
Scope (S): Unchanged. Impacts remain within the vulnerable security authority.
Confidentiality Impact (C): Low. There is a limited impact to this security property.
Integrity Impact (I): None. There is no direct impact to this security property.
Availability Impact (A): Low. There is a limited impact to this security property.
