CVE-2025-54816
This vulnerability occurs when a WebSocket endpoint does not enforce proper authentication mechanisms, allowing unauthorized users to establish connections. As a result, attackers can exploit this weakness to gain unauthorized access to sensitive data or perform unauthorized actions. Given that no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.

CVE-2025-54816: EVMAPA informed CISA some of their charging stations do not allow changes to the authorization key using the Open Charge Point Protocol (OCPP). Currently, charge point operators have the option to connect stations using WebSocket Secure (WSS), and EVMAPA connects stations they supply via their own VPN. For OCPP 2.x and newer stations, EVMAPA plans to implement BASIC authorization control.

CVE-2025-53968
This vulnerability arises because there are no limitations on the number of authentication attempts a user can make. An attacker can exploit this weakness by continuously sending authentication requests, leading to a denial-of-service (DoS) condition. This can overwhelm the authentication system, rendering it unavailable to legitimate users and potentially causing service disruption. This can also allow attackers to conduct brute-force attacks to gain unauthorized access.

CVE-2025-55705
This vulnerability occurs when the system permits multiple simultaneous connections to the backend using the same charging station ID. This can result in unauthorized access, data inconsistency, or potential manipulation of charging sessions. The lack of proper session management and expiration control allows attackers to exploit this weakness by reusing valid charging station IDs to establish multiple sessions concurrently.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
