Overview<\/strong><\/p>\n

The CVE-2025-59358 vulnerability affects the Chaos Controller Manager in Chaos Mesh. This critical flaw exposes a GraphQL debugging server without authentication to the entire Kubernetes cluster, opening the door for potential system compromise or data leakage. The unauthenticated access allows bad actors to kill arbitrary processes in any Kubernetes pod, consequently leading to a cluster-wide denial of service.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-59358
\nSeverity: High (7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Cluster-wide denial of service, potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Chaos Mesh | All versions prior to patch<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of the lack of authentication on the GraphQL debugging server. An attacker with network access to the Kubernetes cluster can send API commands to this debugging server to kill arbitrary processes in any Kubernetes pod. This can lead to a cluster-wide denial of service and potentially compromise the system or leak data.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The below conceptual example demonstrates how the vulnerability might be exploited using a GraphQL mutation request:<\/p>\n

POST \/graphql HTTP\/1.1\nHost: target-cluster.example.com\nContent-Type: application\/json\n{\n\"query\": \"mutation KillProcess($pod: String!) { killProcess(pod: $pod) }\",\n\"variables\": { \"pod\": \"target-pod\" }\n}<\/code><\/pre>\n
In this example, the `killProcess` mutation is used to kill processes in a specific Kubernetes pod identified by the `pod` variable. By repeating this action across multiple pods, an attacker could cause a cluster-wide denial of service.<\/p>\n
Countermeasures and Mitigation<\/strong><\/p>\n
Users are advised to apply the vendor patch as soon as it is available. Until that time, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation. These tools can help block or alert on suspicious network traffic, including the unauthorized GraphQL requests used in this exploit.<\/p>\n","protected":false},"excerpt":{"rendered":"
