CVE-2025-12357

International Standards Organization ISO 15118-2 Improper Restriction of Communication Channel to Intended Endpoints

Published Oct 31, 2025 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
By manipulating the Signal Level Attenuation Characterization (SLAC)
protocol with spoofed measurements, an attacker can stage a
man-in-the-middle attack between an electric vehicle and chargers that
comply with the ISO 15118-2 part. This vulnerability may be exploitable
wirelessly, within close proximity, via electromagnetic induction.

Remediation

Vendor Workaround

ISO recommends using TLS for all communications in accordance with ISO 15118-20. While the use of TLS is recommended in ISO 15118-2, it is required in the ISO 15118-20 revision. TLS should be implemented with certificate chaining. For additional information, please contact the International Electrotechnical Commission https://www.iec.ch/contact .
