Title
Apache ZooKeeper: Information disclosure in persistent watcher handling
Summary
Information disclosure in persistent watchers handling in Apache ZooKeeper due to missing ACL check. It allows an attacker to monitor child znodes by attaching a persistent watcher (addWatch command) to a parent which the attacker has already access to. ZooKeeper server doesn't do ACL check when the persistent watcher is triggered and as a consequence, the full path of znodes that a watch event gets triggered upon is exposed to the owner of the watcher. It's important to note that only the path is exposed by this vulnerability, not the data of znode, but since znode path can contain sensitive information like user name or login ID, this issue is potentially critical. Users are recommended to upgrade to version 3.9.2, 3.8.4 which fixes the issue.

Permite a un atacante monitorear znodes secundarios adjuntando un observador persistente (comando addWatch) a un padre al que el atacante ya tiene acceso. El servidor ZooKeeper no realiza una verificaci\u00f3n de ACL cuando se activa el observador persistente y, como consecuencia, la ruta completa de los znodes sobre los que se activa un evento de vigilancia queda expuesta al propietario del observador. Es importante tener en cuenta que esta vulnerabilidad solo expone la ruta, no los datos de znode, pero dado que la ruta de znode puede contener informaci\u00f3n confidencial como el nombre de usuario o el ID de inicio de sesi\u00f3n, este problema es potencialmente cr\u00edtico. Se recomienda a los usuarios actualizar a la versi\u00f3n 3.9.2, 3.8.4, que soluciona el problema."

It\u0027s important to note that only the path is exposed by this vulnerability, not the data of znode, but since znode path can contain sensitive information like user name or login ID, this issue is potentially critical.\n\nUsers are recommended to upgrade to version 3.9.2, 3.8.4 which fixes the issue."

Permite a un atacante monitorear znodes secundarios adjuntando un observador persistente (comando addWatch) a un padre al que el atacante ya tiene acceso. El servidor ZooKeeper no realiza una verificaci\u00f3n de ACL cuando se activa el observador persistente y, como consecuencia, la ruta completa de los znodes sobre los que se activa un evento de vigilancia queda expuesta al propietario del observador. Es importante tener en cuenta que esta vulnerabilidad solo expone la ruta, no los datos de znode, pero dado que la ruta de znode puede contener informaci\u00f3n confidencial como el nombre de usuario o el ID de inicio de sesi\u00f3n, este problema es potencialmente cr\u00edtico. Se recomienda a los usuarios actualizar a la versi\u00f3n 3.9.2, 3.8.4, que soluciona el problema."
