CVE-2026-44103 is a medium severity vulnerability affecting Phoenix Contact CHARX SEC-3150 version 1.0.0. An unauthenticated remote attacker can inject malicious firmware into the internal charging module because the JupiCore service transmits firmware updates without integrity or verification checks. Exploitation could compromise the device's integrity and may be used in conjunction with CVE-2026-44104.
AI Analysis
Technical Summary
This vulnerability (CWE-434) in Phoenix Contact CHARX SEC-3150 version 1.0.0 allows an unauthenticated remote attacker to upload malicious firmware to the internal charging module. The root cause is that the JupiCore service responsible for firmware updates does not perform any integrity or verification checks on the firmware being transmitted. This lack of validation enables injection of unauthorized firmware, potentially compromising device integrity. The vulnerability has a CVSS 4.0 base score of 6.9 (medium severity) and can be leveraged in combination with CVE-2026-44104 for further impact. No official patch or remediation guidance has been published by the vendor as of now.
Potential Impact
Successful exploitation allows an unauthenticated remote attacker to inject malicious firmware into the device's internal charging module, compromising the integrity of the affected device. This could lead to unauthorized control or disruption of device functionality. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary mitigation is currently available, closely monitor vendor communications for updates. Until a patch is released, restrict network access to the device and consider additional network-level protections to limit exposure.
