Privileged charm actions via abstract agent socket
Published Oct 2, 2024 · Updated Nov 1, 2024
Improper access control in Canonical Juju affected releases allows local users to invoke privileged charm actions through an agent socket. The NewWorkerPaths logic prefixes LocalJujucServerSocket with @, creating an abstract UNIX socket that bypasses filesystem access controls. Exploitation requires low-privileged local access to the default network namespace and a usable JUJU_CONTEXT_ID; available actions depend on the charm.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=2.9 <2.9.51
- Affected versionversion=3.1 <3.1.10
- Affected versionversion=3.3 <3.3.7
- Affected versionversion=3.4 <3.4.6
