CVE-2026-9037: CWE-494 Download of code without integrity check in XCharge C6
A firmware update mechanism in the affected charging controller fails to validate the authenticity of firmware packages delivered through the device's management interface. Because cryptographic signatures are not verified, an attacker with the ability to interfere with or impersonate the management channel could cause the device to install an unauthorized firmware package. This condition could allow execution of unauthorized code with high privileges on the device.
AI Analysis
Technical Summary
The XCharge C6 charging controller contains a vulnerability (CVE-2026-9037) due to its firmware update process failing to validate cryptographic signatures on firmware packages. This CWE-494 weakness permits an attacker capable of interfering with the device's management channel to deliver and install malicious firmware. The vulnerability has a CVSS 4.0 score of 9.3, indicating critical severity with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows execution of unauthorized code with high privileges on the affected device, potentially compromising device integrity and control. This could disrupt device operation or enable further attacks on connected infrastructure. 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. Until an official fix is available, restrict access to the device's management interface to trusted networks and monitor for unauthorized firmware update attempts. Avoid exposing the management channel to untrusted networks to reduce risk.
