Lifecycle Timeline
4Description
In Juju from version 3.0.0 through 3.6.18, when a secret owner grants permissions to a secret to a grantee, the secret owner relies exclusively on a predictable XID of the secret to verify ownership. This allows a malicious grantee which can request secrets to predict past secrets granted by the same secret owner to different grantees, allowing them to use the resources granted by those past secrets. Successful exploitation relies on a very specific configuration, specific data semantic, and the administrator having the need to deploy at least two different applications, one of them controlled by the attacker.
Analysis
A predictable secret identifier (XID) vulnerability in Juju versions 3.0.0 through 3.6.18 allows a malicious grantee to enumerate and predict previously granted secrets owned by the same administrator, enabling unauthorized access to resources intended for other applications. An attacker with high privileges and control over at least one deployed application can exploit this to obtain credentials or configuration data from past secret grants, resulting in information disclosure and potential privilege escalation. …
