Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.
Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
Directly implements checks on information inputs to reject invalid data before processing.
Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Vulnerability directly enables Endpoint DoS via application/system exploitation by triggering assert failures through malformed input, causing full manager shutdown.
NVD Description
EVerest is an EV charging software stack. Prior to version 2025.10.0, the use of the `assert` function to handle errors frequently causes the module to crash. This is particularly critical because the manager shuts down all other modules and exits…

when any one of them terminates, leading to a denial of service. In a context where a manager handles multiple EVSE, this would also impact other users. Version 2025.10.0 fixes the issue.
Deeper analysisAI
CVE-2025-68134 is a vulnerability in EVerest, an open-source EV charging software stack, affecting versions prior to 2025.10.0. The issue arises from the frequent use of the assert() function for error handling, which causes individual modules to crash (CWE-20: Improper Input Validation). This is exacerbated by the EVerest manager's behavior, which shuts down all other modules and exits upon any module termination, resulting in a denial-of-service condition. The vulnerability has a CVSS v3.1 base score of 7.4 (AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H).
An attacker with adjacent network access can exploit this vulnerability with low attack complexity, requiring no privileges or user interaction. By triggering an assert() failure in a module—such as through malformed inputs or unexpected conditions—the attacker causes the module to crash, prompting the manager to terminate all modules and exit. This leads to a high-impact denial of service on the affected EV charging system. In multi-EVSE (Electric Vehicle Supply Equipment) deployments managed by a single instance, the outage impacts other users sharing the manager.
The GitHub security advisory (GHSA-cxc5-rrj5-8pf3) at https://github.com/EVerest/everest-core/security/advisories/GHSA-cxc5-rrj5-8pf3 confirms that version 2025.10.0 resolves the issue by addressing the improper use of assert() for error handling. Security practitioners should prioritize upgrading to this version or later to mitigate the denial-of-service risk.
