CVE-2026-9037
Description
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 Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Unauthenticated firmware update in XCharge C6 allows remote code execution due to missing cryptographic signature verification.
Vulnerability
The XCharge C6 charging controller contains a vulnerability in its firmware update mechanism. The device fails to validate the authenticity of firmware packages delivered through the management interface; cryptographic signatures are not verified. This allows an attacker to supply unauthorized firmware. Affected versions are all XCharge C6 versions prior to May 22, 2026 [1].
Exploitation
An attacker with the ability to interfere with or impersonate the management channel can deliver a malicious firmware package. The management interface is accessible over the network. The attacker can craft a fake firmware update and send it to the device, which will install it without signature verification, executing the attacker's code [1].
Impact
Successful exploitation allows the attacker to execute unauthorized code with high privileges on the device, potentially gaining full administrative control [1].
Mitigation
Users should update the XCharge C6 firmware to the latest version available after May 22, 2026. No workarounds have been published. The vulnerability is critical with a CVSS score of 9.8 [1].
