CVE-2026-40702: CWE-306 in EVoke EVoke CSMS
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to impersonate charging stations. 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.
AI Analysis
Technical Summary
CVE-2026-40702 is a critical security vulnerability in EVoke EVoke CSMS caused by the absence of authentication mechanisms on WebSocket endpoints. This weakness enables attackers to impersonate legitimate charging stations, gaining unauthorized access and performing unauthorized operations. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function). The CVSS v3.1 base score is 9.4, reflecting high impact on confidentiality, integrity, and low impact on availability. No patch or official remediation has been documented yet, and the product is not a cloud service.
Potential Impact
Exploitation of this vulnerability allows attackers to impersonate charging stations, leading to unauthorized access to sensitive information and the ability to perform unauthorized actions within the EVoke CSMS environment. This can result in privilege escalation and potentially compromise the security and integrity of the entire charging management system.
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 WebSocket endpoints through network controls and monitor for unauthorized connections. Implement additional authentication mechanisms at the network or application layer if possible to mitigate unauthorized access risks.
