NVD · unedited
Katana Network Development Starter Kit executeCommand Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Katana Network Development Starter Kit. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the executeCommand method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-27786.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a command injection vulnerability in the executeCommand method of Katana Network Development Starter Kit. The flaw results from insufficient validation of user-supplied input before it's used in a system call, allowing unauthenticated remote attackers to execute arbitrary code in the context of the service account.

MitigationImplement strict input validation and sanitization on all user-supplied parameters, preferably using allowlists and avoiding system calls with user input entirely. Replace dynamic command construction with parameterized APIs or safe libraries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Katana Network Development Starter Kit installation
    Search for the product in your system using package managers, installed software lists, or by locating its main executable and configuration directories
    Affected if The software is present on the system
  2. Identify the installed version
    Run the product's version command, check its about dialog, or inspect version files in the installation directory
    Affected if The installed version falls within any affected version range or cannot be determined and the product is present
  3. Verify executeCommand method exposure
    Review application configuration, network service settings, and API endpoints to determine if the executeCommand method is exposed as a network service or API
    Affected if The executeCommand method is accessible via network, API, or web interface without authentication
  4. Check input validation configuration
    Examine application logs, security settings, or input handling configuration to determine if user-supplied input reaches executeCommand without sanitization
    Affected if User-controlled input can be passed directly to executeCommand without validation filters
  5. Assess network accessibility
    Test whether the service hosting executeCommand is bound to network interfaces accessible from untrusted sources
    Affected if The vulnerable endpoint is reachable from untrusted network segments or the internet

The environment is affected if Katana Network Development Starter Kit is installed with the executeCommand method exposed to untrusted input, regardless of version, as the vulnerability allows remote code execution with service account privileges.
