Insecure Direct Object Reference attack via predictable secret ID in Juju

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.

Juju 安全漏洞

Juju是Canonical Juju开源的一个开源应用程序编排引擎。 Juju 3.0.0至3.6.18版本存在安全漏洞，该漏洞源于密钥所有者仅依赖可预测的XID验证所有权，可能导致恶意被授权者预测过去授予其他被授权者的密钥并使用其资源。
