CVE-2023-2759
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 · uneditedA hidden API exists in TapHome's core platform before version 2023.2 that allows an authenticated, low privileged user to change passwords of other users without any prior knowledge. The attacker may gain full access to the device by using this vulnerability.
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 confidenceA hidden API endpoint in TapHome's core platform before version 2023.2 allows any authenticated user, regardless of privilege level, to change passwords of other users without requiring the current password or proper authorization. This broken access control vulnerability enables privilege escalation, allowing a low-privileged attacker to reset admin credentials and gain full device access.

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 TapHome Core Firmware versionAccess the TapHome admin interface or check system information page to find the installed firmware version. This is typically found in Settings > System > About or similar location depending on interface layout.Affected if The installed version is earlier than 2023.2 (for example, 2023.1, 2022.x, or earlier)
-
Locate the hidden password change API endpointReview API documentation or intercept network traffic during password change operations. Common endpoint patterns include /api/user/password, /api/admin/reset-password, or similar paths under the /api/ directory. Check for undocumented endpoints not shown in official API docs.Affected if A password change endpoint exists that accepts user ID or username parameters without requiring the current password
-
Verify authorization requirements on password change endpointsUse a low-privileged test account to attempt changing the password of a different user (such as another standard user or an administrator). Capture and analyze the HTTP request and response to see if the endpoint validates the caller's privileges.Affected if The endpoint accepts and processes password change requests for other users without validating that the caller has administrative privileges
-
Test for privilege escalation via password resetWith a standard (non-admin) account, attempt to change the password of an administrator account through the API. Check if the system allows this without requiring admin-level permissions or the current password.Affected if A low-privileged user can successfully change an administrator password, confirming the broken access control vulnerability
-
Review user privilege configurationExamine the user management panel or user database to confirm privilege levels assigned to different user accounts. Verify that the system properly distinguishes between admin and standard user roles.Affected if Multiple privilege levels exist but the password change API does not enforce role-based access control
A defender is affected if their TapHome Core Firmware version is earlier than 2023.2 AND the system contains a password change API endpoint accessible to any authenticated user without proper authorization checks.

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.
dbcve · scoped2023.2
Upgrade TapHome core platform to version 2023.2 or later, which removes or properly secures the hidden API endpoint. Additionally, audit all API endpoints for proper authorization checks.
2023.2
- Identify the TapHome device running the Core Firmware
- Check the current firmware version to confirm it is below 2023.2
- Obtain the firmware version 2023.2 or later from the official TapHome source
- Apply the firmware upgrade following TapHome's official upgrade procedure
- Verify the upgrade was successful and the version is now 2023.2 or later
