Vulnerability Data

EVerest is an EV charging software stack. Prior to version 2026.02.0, even immediately after CSMS performs a RemoteStop (StopTransaction), the EVSE can return to `PrepareCharging` via the EV's BCB toggle, allowing session restart. This breaks the irreversibility of remote stop…

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces authorization decisions so that a completed RemoteStop cannot be reversed by an EV BCB toggle without re-authentication.

AC-12 Session Termination partial match
prevent

Requires immediate and irreversible session termination after RemoteStop, blocking unauthorized return to PrepareCharging state.

SI-10 Information Input Validation partial match
prevent

Validates EVSE inputs (BCB toggle) against current authorization/session state to reject restarts after a CSMS stop command.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.15 Access control partial match
prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

A.5.18 Access rights partial match
prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

A.8.3 Information access restriction partial match
prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
