CVE-2025-5750
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWOLFBOX Level 2 EV Charger tuya_svc_devos_activate_result_parse Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of WOLFBOX Level 2 EV Charger. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the secKey, localKey, stdTimeZone and devId parameters. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26294.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceHeap-based buffer overflow in WOLFBOX Level 2 EV Charger during parsing of secKey, localKey, stdTimeZone, and devId parameters. The device fails to validate the length of user-supplied data before copying into fixed-size heap buffers, allowing network-adjacent attackers to achieve RCE without authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelLocate the EV charger and verify it is a Wolfbox Level 2 EV Charger by checking the physical device label, packaging, or management interface for the model nameAffected if The device is not a Wolfbox Level 2 EV Charger
-
Check the firmware versionAccess the charger admin interface or check via the manufacturer's app, and identify the installed firmware version numberAffected if The firmware version is 3.1.17
-
Determine network exposure of the management interfaceCheck if the charger's web-based or API management interface is accessible from network segments beyond a trusted local network, including whether it is directly exposed to the internet or untrusted VLANsAffected if The management interface is reachable from untrusted network segments
-
Verify if vulnerable parameters are configurableExamine the device settings for configurable parameters named secKey, localKey, stdTimeZone, or devId - these are typically found in network or time configuration sections of the admin interfaceAffected if These parameters exist and can be modified through the interface
You are affected if you have a Wolfbox Level 2 EV Charger running firmware version 3.1.17 with its management interface accessible from network-adjacent attackers.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor firmware patch when available; until then, restrict network access to the charger via firewall/VLAN segmentation to limit exposure to adjacent attackers.
