CVE-2026-44100: CWE-306 Missing Authentication for Critical Function in Phoenix Contact CHARX SEC-3150
CVE-2026-44100 is a high-severity vulnerability in the Phoenix Contact CHARX SEC-3150 device, specifically in the CHARX JupiCore service. It allows unauthenticated remote attackers to reconfigure charging points, potentially leading to disclosure of charging point unique identifiers (UIDs), denial-of-service conditions, and file tampering. The vulnerability is due to missing authentication for critical functions (CWE-306). Only version 1.0.0 of the product is explicitly affected. No official patch or remediation guidance has been provided yet.
AI Analysis
Technical Summary
The CHARX JupiCore service in Phoenix Contact CHARX SEC-3150 version 1.0.0 lacks authentication controls for critical functions, enabling unauthenticated remote attackers to reconfigure charging points. This vulnerability can result in unauthorized disclosure of charging point UIDs, denial-of-service, and tampering with files. The CVSS 4.0 base score is 8.8, reflecting high impact with network attack vector, no required privileges or user interaction, and high impact on integrity and availability. No patch or official remediation level has been disclosed as of the publication date.
Potential Impact
An attacker can remotely and without authentication reconfigure charging points, which may lead to disclosure of sensitive identifiers, disruption of charging services (denial-of-service), and unauthorized modification of files on the device. This compromises the integrity and availability of the charging infrastructure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the CHARX JupiCore service to trusted entities only and monitor for unauthorized configuration changes if possible.
