Canonical: >> Juju Security Vulnerabilities
In Juju versions prior to 3.6.8 and 2.9.52, any authenticated controller user was allowed to upload arbitrary agent binaries to any model or to the controller itself, without verifying model membership or requiring explicit permissions. This enabled the distribution of poisoned binaries to new or upgraded machines, potentially resulting in remote code execution.

The /charms endpoint on a Juju controller lacked sufficient authorization checks, allowing any user with an account on the controller to upload a charm. Uploading a malicious charm that exploits a Zip Slip vulnerability could allow an attacker to gain access to a machine running a unit through the affected charm.

JUJU_CONTEXT_ID is a predictable authentication secret. On a Juju machine (non-Kubernetes) or Juju charm container (on Kubernetes), an unprivileged user in the same network namespace can connect to an abstract domain socket and guess the JUJU_CONTEXT_ID value. This gives the unprivileged user access to the same information and tools as the Juju charm.

Vulnerable juju hook tool abstract UNIX domain socket. When combined with an attack of JUJU_CONTEXT_ID, any user on the local system with access to the default network namespace may connect to the @/var/lib/juju/agents/unit-xxxx-yyyy/agent.socket and perform actions that are normally reserved to a juju charm.

Vulnerable juju introspection abstract UNIX domain socket. An abstract UNIX domain socket responsible for introspection is available without authentication locally to network namespace users. This enables denial of service attacks.

An issue was discovered in Juju that resulted in the leak of the sensitive context ID, which allows a local unprivileged attacker to access other sensitive data or relation accessible to the local charm.

Juju before 1.25.12, 2.0.x before 2.0.4, and 2.1.x before 2.1.3 uses a UNIX domain socket without setting appropriate permissions, allowing privilege escalation by users on the system to root.
