Overview
The Common Vulnerabilities and Exposures (CVE) system has identified a critical vulnerability, CVE-2025-59359, that affects the Chaos Controller Manager, specifically the cleanTcs mutation function. This vulnerability allows for Operating System (OS) command injection, posing a severe threat to system integrity and data confidentiality. Coupled with the CVE-2025-59358 vulnerability, an unauthenticated in-cluster attacker can perform remote code execution across the cluster. Given its severity and potential impacts, this vulnerability is a cause for concern for all users of the affected products.

How the Exploit Works
The vulnerability resides in the cleanTcs mutation function of the Chaos Controller Manager. The flaw allows for command injection, a type of attack where the attacker can control the OS commands that the system executes. When coupled with the CVE-2025-59358 vulnerability, this command injection flaw enables remote code execution across the cluster, even by unauthenticated in-cluster attackers. In essence, the attackers gain the ability to execute arbitrary commands at the system level, leading to a complete system compromise and potential data leak.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited:
POST /cleanTcs HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"command": "; rm -rf / ;"
}
In this example, the malicious command “; rm -rf / ;” injected into the cleanTcs mutation function would delete all files in the system if executed.
Mitigation
The best mitigation for this vulnerability is to apply the vendor’s patch as soon as it becomes available. Until then, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. However, these are not foolproof and do not address the root cause of the vulnerability. Therefore, applying the vendor patch should be the priority for all users of the affected products.
