CVE-2026-44104: CWE-347 Improper Verification of Cryptographic Signature in Phoenix Contact CHARX SEC-3150
The Phoenix Contact CHARX SEC-3150 charging controller version 1.0.0 has a vulnerability in its firmware update process where only a CRC32 checksum is validated without cryptographic signature verification. This flaw allows an unauthenticated remote attacker to install modified firmware, leading to full system compromise. The vulnerability is classified as CWE-347 (Improper Verification of Cryptographic Signature) and has a critical severity with a CVSS 4.0 score of 9.3.
AI Analysis
Technical Summary
CVE-2026-44104 affects the Phoenix Contact CHARX SEC-3150 charging controller basemodule firmware update process. The update mechanism validates only the CRC32 checksum but does not verify a cryptographic signature. This improper verification (CWE-347) enables an unauthenticated remote attacker to install malicious firmware, resulting in complete control over the system. The vulnerability is present in version 1.0.0 of the product. No official patch or remediation has been published as of the data provided.
Potential Impact
An attacker can remotely and without authentication install modified firmware on the device, leading to full system compromise. This can result in unauthorized control over the charging controller, potentially disrupting operations or causing further security breaches.
Mitigation Recommendations
No official fix or patch is currently available. Users should monitor vendor advisories for updates. Until a patch is released, restrict network access to the device's firmware update interface to trusted sources only to reduce exposure. Avoid applying firmware updates from untrusted networks or sources.
