CVE-2026-77054 Details
Description
boneIO Black stores passwords, including the MQTT broker and web panel passwords, in cleartext. The GET /api/config endpoint returns the full configuration with sub-services passwords exposed. Any authenticated user can call the endpoint and access the administrative passwords in cleartext form. Critically, due to CVE-2026-77053 (authentication disabled by default), an unauthenticated attacker on the same local network can retrieve all passwords. This issue was fixed in version 1.6.0: web panel passwords are stored as salted scrypt hashes in a file readable only by the service account, and the API and logs no longer return secret values. The MQTT broker password has to stay recoverable because the application presents it to the broker as a client; it is kept in a separate file readable only by the service account and is no longer exposed through the API.
A vulnerability exists in boneIO Black versions 1.2.0 prior to 1.6.0, where passwords, including those for the MQTT broker and web panel, are stored in cleartext. The issue is compounded by authentication being disabled by default, allowing unauthenticated attackers on the same local network to access sensitive information. The vulnerability can be exploited by calling the GET /api/config endpoint, which returns the full configuration with exposed passwords. This issue has been addressed in version 1.6.0, which introduced secure password storage and removed sensitive information from the API and logs.
Users can upgrade to boneIO Black version 1.6.0, which fixes this vulnerability by implementing secure password storage and ensuring that the API and logs no longer expose sensitive values. Instructions for upgrading are available in the boneIO Black documentation.
