Descripción

*** Pendiente de traducción *** A flaw was found in the Ansible Automation Platform automation-controller. The unauthenticated<br /> Bitbucket Data Center webhook receiver skips HMAC signature verification for diagnostics:ping<br /> events after it has already looked up the target template, causing the endpoint to return HTTP<br /> 200 for a template that has a Bitbucket DC webhook configured and HTTP 403 otherwise. An<br /> unauthenticated remote attacker can use this response discrepancy as an oracle to enumerate<br /> which Job Template and Workflow Job Template IDs have Bitbucket DC webhooks configured, without<br /> knowing the secret webhook_key.
