AI risk analysis

Summary: The flaw allows unauthenticated attackers to bypass authentication in Dockhand's git webhook endpoints, enabling arbitrary stack redeployments and potentially leading to full host compromise.
Exploitability: Exploitation is relatively straightforward as it requires sending unsigned webhook requests to the git webhook endpoints. Attackers must enumerate stack IDs and have write access to the tracked git branch.
Blast radius: If exploited, the impact could be severe, leading to denial of service, container escape, and full host compromise.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Dockhand 1.0.40 or later.

NVD description

Dockhand before 1.0.40 contains an authentication bypass vulnerability in its git webhook endpoints that allows unauthenticated remote attackers to trigger arbitrary stack redeployments by exploiting a null webhook secret guard condition. Attackers can enumerate sequential stack IDs and send unsigned webhook requests to force git clone and docker compose operations, enabling denial of service or, when combined with write access to the tracked git branch, container escape and full host compromise via attacker-controlled docker-compose.yml with privileged bind mounts.
