4DescriptionGitHub Advisory
EVerest is an EV charging software stack. Prior to versions to 2026.02.0, ISO15118_chargerImpl::handle_session_setup copies a variable-length payment_options list into a fixed-size array of length 2 without bounds checking. With schema validation disabled by default, oversized MQTT Cmd payloads can trigger out-of-bounds writes and corrupt adjacent EVSE state or crash the process. Version 2026.02.0 contains a patch.
AnalysisAI
Out-of-bounds memory writes in EVerest charging software stack versions prior to 2026.02.0 allow local attackers to corrupt EVSE state or crash the charging process by sending oversized MQTT command payloads that bypass disabled schema validation. The ISO15118_chargerImpl::handle_session_setup function copies variable-length payment_options lists into a fixed 2-element array without bounds checking, exposing a CWE-787 buffer overflow vulnerability with availability and integrity impact. No public exploit code has been identified at time of analysis.
Technical ContextAI
EVerest is an open-source EV charging software stack (CPE: cpe:2.3:a:everest:everest-core) that implements ISO 15118 standard charging protocols. The vulnerability resides in the ISO15118_chargerImpl::handle_session_setup function, which processes MQTT command payloads containing payment options negotiation. The root cause is a classic CWE-787 out-of-bounds write vulnerability: the function uses memcpy or similar operations to copy a dynamically-sized payment_options array from untrusted MQTT message data into a fixed-size stack or heap buffer of exactly 2 elements. Schema validation, which would normally constrain payload sizes at the message boundary, is disabled by default in affected versions. This allows an attacker crafting malicious MQTT Cmd messages to trigger buffer overflow conditions, overwriting adjacent EVSE (Electric Vehicle Supply Equipment) state structures or corrupting the runtime heap, leading to process crashes or state corruption.
RemediationAI
Upgrade EVerest Core to version 2026.02.0 or later, which contains the patch that adds proper bounds checking to the ISO15118_chargerImpl::handle_session_setup function. See the security advisory at https://github.com/EVerest/EVerest/security/advisories/GHSA-7wmg-crc8-6xxf for detailed upgrade instructions. As an interim mitigation before patching is feasible, enable schema validation at the MQTT message boundary (reverse the default-disabled state) to enforce payload size constraints, restrict MQTT broker access to trusted networks only via firewall rules, and monitor MQTT traffic for oversized Cmd payloads targeting payment_options fields. Monitor system logs for unexpected EVerest process crashes that may indicate exploitation attempts.
