CVE-2026-44104: CWE-347 Improper Verification of Cryptographic Signature in Phoenix Contact CHARX SEC-3150
CVE-2026-44104 is a critical vulnerability in the Phoenix Contact CHARX SEC-3150 charging controller firmware update process. The affected firmware version 1.0.0 only verifies a CRC32 checksum during updates and lacks cryptographic signature verification. This allows an unauthenticated remote attacker to install modified firmware, potentially leading to full system compromise. No official patch or remediation guidance is currently available.
AI Analysis
Technical Summary
The vulnerability CVE-2026-44104 affects Phoenix Contact CHARX SEC-3150 version 1.0.0. The firmware update process for the basemodule verifies only a CRC32 checksum instead of a cryptographic signature, which is insufficient to ensure firmware authenticity and integrity. This flaw enables unauthenticated remote attackers to install maliciously modified firmware, risking complete control over the device. The CVSS 4.0 score is 9.3, indicating critical severity. There is no known official fix or mitigation at this time.
Potential Impact
An unauthenticated remote attacker can exploit this vulnerability to install arbitrary modified firmware on the CHARX SEC-3150 device. This can lead to full system compromise, including unauthorized control and potential disruption of device functionality.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Users should monitor vendor communications for updates and consider restricting network access to the device to reduce exposure until a fix is provided.
