Detailsinfo

A vulnerability, which was classified as very critical, was found in boneIO black_debian_images up to 1.5.x. Affected is an unknown function. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

boneIO black_debian_images gives the boneio service account excessive privileges, including full passwordless sudo access and membership in the docker group. A local attacker who compromises the boneio user can use these privileges to escalate to root. This issue was fixed in version 1.6.0: the image removes the sudoers rule and the docker group membership when it is sealed, and devices already in the field have both removed by migrations shipped with boneio 1.6.0 and applied on first start after the upgrade. Privileged operations now go through helpers that accept only a fixed set of commands, with migrations verified against Ed25519 signatures.

The advisory is shared for download at cert.pl. This vulnerability is traded as CVE-2026-77055 since 08/20/2026. The exploitability is told to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 10/26/2026). The MITRE ATT&CK project declares the attack technique as T1068.

Upgrading to version 1.6.0 eliminates this vulnerability.
