CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in ISO 15118-2 Network and Application Protocol Requirements 8.3. It has been classified as critical. This affects an unknown functionality of the component Signal Level Attenuation Characterization Protocol Handler. The manipulation with an unknown input leads to a communication channel to intended endpoints vulnerability. CWE is classifying the issue as CWE-923. The product establishes a communication channel to (or from) an endpoint for privileged or protected operations, but it does not properly ensure that it is communicating with the correct endpoint. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at cisa.gov. This vulnerability is uniquely identified as CVE-2025-12357. The exploitability is told to be easy. The attack can only be done within the local network. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The best possible mitigation is suggested to be adding encryption.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-37371). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
