External lookup

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-2026-3519.

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.

Product CPE queries

Derived from this CVE's existing NVD CPE 2.3 records; the application, operating-system, or hardware part is retained.

How this vector reads

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

Attack Vector (AV): Adjacent. The attacker must reach the same or an adjacent network.
Attack Complexity (AC): Low. No special conditions beyond the attacker-controlled steps are required.
Privileges Required (PR): High. The attacker needs significant administrative privileges.
User Interaction (UI): None. Exploitation does not require another user to act.
Scope (S): Changed. Impacts can cross into a different security authority.
Confidentiality Impact (C): High. There is a total or serious impact to this security property.
Integrity Impact (I): High. There is a total or serious impact to this security property.
Availability Impact (A): High. There is a total or serious impact to this security property.
