User description

Type Identifier Message Severity Link
Application
CWE-78
The application fails to sanitize untrusted input leading to OS command injection. The command execution uses ProcessBuilder which directly concatenates unvalidated HTTP header input. This exposes the application to critical command injection vulnerabilities.

CodeAnt-AI Description

Prevent OS command injection by passing user input as echo argument

What Changed

  • The server no longer builds a shell command by concatenating untrusted HTTP input; the input is passed as a separate argument to echo to avoid being interpreted as shell syntax.
  • The endpoint still returns the echoed input, but inputs containing shell metacharacters will no longer run additional commands on the host.
  • A clarifying comment was added to indicate the security intent of the change.

Impact

✅ Prevents OS command injection from untrusted HTTP input
✅ Echo responses no longer execute injected shell commands
✅ Lower risk of remote command execution in request handling
