Executive Summary

The vulnerability in CVE-2025-59359 is an OS command injection flaw in the cleanTcs mutation of the Chaos Controller Manager. This flaw allows unauthenticated attackers within the cluster to execute arbitrary code remotely across the cluster, especially when combined with CVE-2025-59358.

Impact Analysis

This vulnerability can have a severe impact by allowing unauthenticated attackers inside the cluster to perform remote code execution. This means attackers could potentially take full control over the cluster, leading to data breaches, service disruption, or further exploitation.

Mitigation Strategies

To mitigate the vulnerability, disable the `chaosctl` server by setting the `enableCtrlServer` configuration value to false in your Helm chart values. This prevents the `chaosctl` server from running and reduces the attack surface. Note that the `chaosctl` server listens on port 10082, so ensure this service is not enabled or accessible. Also, be aware of a bug in the `install.sh` script that may remove the `ctrl` server configurations entirely, which affects enabling or disabling the server. Applying the fix from pull request #4702 or upgrading to versions where this fix is cherry-picked (release branches 2.6 and 2.7) is recommended. [1]
