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

The vulnerability CVE-2025-53355 pertains to MCP Server Kubernetes, a server that connects to and manages a Kubernetes cluster. This vulnerability is particularly significant due to its potential to allow an attacker to inject arbitrary system commands, leading to remote code execution under the server process’s privileges.<\/p>\n

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

CVE ID: CVE-2025-53355
\nSeverity: High – 7.5 (CVSS score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

MCP Server Kubernetes | Versions prior to 2.5.0<\/p>\n

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

The vulnerability is caused by unsanitized input parameters within a call to child_process.execSync in the MCP Server Kubernetes. This exploit takes advantage of the server’s lack of proper input sanitization to inject arbitrary system commands.<\/p>\n

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

A conceptual example of how the vulnerability might be exploited is as follows:<\/p>\n

$ curl -X POST -H \"Content-Type: application\/json\" -d '{\"command\": \"; arbitrary_system_command ;\"}' http:\/\/target.example.com\/vulnerable\/endpoint<\/code><\/pre>\n
In this example, the attacker sends a POST request to the vulnerable endpoint with a JSON payload containing an arbitrary system command. The command is injected into the system via the unsanitized `command` field, which is processed by `child_process.execSync`, leading to the execution of the injected command.<\/p>\n
Mitigation<\/strong><\/p>\n
The recommended mitigation method is to apply the vendor patch, namely, the upgrade to version 2.5.0 which contains a fix for the vulnerability. As a temporary mitigation, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help to filter out malicious payloads.<\/p>\n","protected":false},"excerpt":{"rendered":"
