CVE-2025-2765
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 · uneditedCarlinKit CPC200-CCPA Wireless Hotspot Hard-Coded Credentials Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of CarlinKit CPC200-CCPA devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the configuration of the wireless hotspot. The issue results from the use of hard-coded credentials. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-24349.
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 confidenceThe CarlinKit CPC200-CCPA wireless hotspot device contains hard-coded credentials embedded in its firmware configuration. An attacker with network adjacency to the device can exploit these static credentials to bypass the authentication mechanism entirely, gaining full access without requiring any valid user credentials.

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 CarlinKit device on networkInspect your network inventory or physically examine devices for CarlinKit, Carlinkit, CPC200-CCPA, or Autokit branding. Check device labels, management interfaces, or DHCP lease tables for these identifiers.Affected if A CarlinKit wireless hotspot device is present on the network
-
Check device firmware versionAccess the device admin panel via its IP address, or use methods like SNMP, UPnP discovery, or checking the device's web interface for a firmware/version information page. Look for version number 2024.01.19.1541.Affected if The installed firmware version is exactly 2024.01.19.1541
-
Verify wireless hotspot is enabledLog into the device admin interface and navigate to wireless settings or hotspot configuration. Confirm whether the wireless hotspot functionality is turned on and broadcasting.Affected if The wireless hotspot feature is enabled and broadcasting
-
Assess network accessibilityDetermine if the device is accessible from untrusted network segments. Use port scanning or network topology review to check if the device management interface (typically HTTP/HTTPS on ports 80, 443, or 8080) is exposed to network segments outside a trusted VLAN.Affected if The device management interface is reachable from untrusted network segments without firewall isolation
You are affected if you have a CarlinKit Autokit device running firmware version 2024.01.19.1541 with its wireless hotspot enabled and accessible from an untrusted network segment.

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 dataNetwork segmentation should isolate the device from untrusted networks. If the device supports credential changes, immediately replace hard-coded credentials with strong, unique passwords. Consider disabling the wireless hotspot if unnecessary, and monitor for unauthorized access attempts.
