AI Analysis
Technical Summary
This vulnerability (CVE-2026-44100) in Phoenix Contact CHARX SEC-3150 version 1.0.0 involves missing authentication controls in the CHARX JupiCore service. Because critical functions can be accessed without authentication, remote attackers can reconfigure charging points, potentially exposing unique identifiers, causing denial-of-service, and modifying files on the device. The CVSS 4.0 score is 8.8 (high severity), reflecting network attack vector, no privileges or user interaction required, and high impact on integrity and availability.
Potential Impact
An attacker can remotely and without authentication reconfigure charging points, leading to disclosure of unique identifiers, denial-of-service conditions, and unauthorized file tampering on the device. This compromises device integrity and availability, potentially disrupting charging infrastructure operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict network access to the CHARX JupiCore service to trusted entities only.
