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.
Analysis
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.
Technical ContextAI
Remote code execution allows an attacker to run arbitrary commands or code on the target system over a network without prior authentication. This vulnerability is classified as Improper Authorization (CWE-285).
RemediationAI
Apply vendor patches immediately. Restrict network access to vulnerable services. Implement network segmentation and monitoring for anomalous activity.
