CRITICAL SEVERITY (CVSS 9.0-10.0)

V-001: Command Injection via shell=True in Subprocess Calls

  • CVSS Score: 9.8 (Critical)
  • Location: tools/terminal_tool.py, tools/file_operations.py, tools/environments/*.py
  • Description: Multiple subprocess calls use shell=True with user-controlled input, enabling arbitrary command execution
  • Attack Vector: Local/Remote via agent prompts or malicious skills
  • Evidence:
    # terminal_tool.py line ~460
    subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, ...)
    # Command strings constructed from user input without proper sanitization
    
  • Impact: Complete system compromise, data exfiltration, malware installation

4. SECURE CODING GUIDELINES

4.1 Command Execution

# ❌ NEVER DO THIS
subprocess.run(f"ls {user_input}", shell=True)

# ✅ DO THIS
subprocess.run(["ls", user_input], shell=False)

# ✅ OR USE SHLEX
import shlex
subprocess.run(["ls"] + shlex.split(user_input), shell=False)

4.2 Path Handling

# ❌ NEVER DO THIS
open(os.path.expanduser(user_path), "r")

# ✅ DO THIS
from pathlib import Path
safe_root = Path("/allowed/path").resolve()
user_path = Path(user_path).expanduser().resolve()
if not str(user_path).startswith(str(safe_root)):
    raise PermissionError("Path outside sandbox")

4.3 Secret Handling

# ❌ NEVER DO THIS
os.environ["API_KEY"] = user_api_key  # Visible to all child processes

# ✅ DO THIS
# Use file descriptor passing or explicit whitelisting
child_env = {k: v for k, v in os.environ.items() 
             if k in ALLOWED_ENV_VARS}

4.4 URL Validation

# ❌ NEVER DO THIS
response = requests.get(user_url)

# ✅ DO THIS
from urllib.parse import urlparse
parsed = urlparse(user_url)
if parsed.scheme not in ("http", "https"):
    raise ValueError("Invalid scheme")
if parsed.hostname not in ALLOWED_HOSTS:
    raise ValueError("Host not allowed")

4.5 Input Validation

# Use pydantic for all user inputs
from pydantic import BaseModel, validator

class FileRequest(BaseModel):
    path: str
    max_size: int = 1000
    
    @validator('path')
    def validate_path(cls, v):
        if '..' in v or v.startswith('/'):
            raise ValueError('Invalid path')
        return v

# CURRENT CODE (tools/terminal_tool.py ~line 457)
cmd = [self._docker_exe, "exec", "-w", work_dir, self._container_id, 
       "bash", "-lc", exec_command]

# SECURE FIX
cmd = [self._docker_exe, "exec", "-w", work_dir, self._container_id, 
       "bash", "-lc", exec_command]
# Add strict input validation before this point
if not _is_safe_command(exec_command):
    raise SecurityError("Dangerous command detected")

Fix 2: File Operations Path Traversal (V-002)

# CURRENT CODE (tools/file_operations.py ~line 409)
def _expand_path(self, path: str) -> str:
    if path.startswith('~'):
        # ... expansion logic

# SECURE FIX
def _expand_path(self, path: str) -> str:
    safe_root = Path(self.cwd).resolve()
    expanded = Path(path).expanduser().resolve()
    if not str(expanded).startswith(str(safe_root)):
        raise PermissionError(f"Path {path} outside allowed directory")
    return str(expanded)

Fix 3: Code Execution Environment Sanitization (V-003)

# CURRENT CODE (tools/code_execution_tool.py ~lines 434-461)
_SAFE_ENV_PREFIXES = ("PATH", "HOME", "USER", ...)
_SECRET_SUBSTRINGS = ("TOKEN", "SECRET", ...)

# SECURE FIX - Whitelist approach
_ALLOWED_ENV_VARS = frozenset([
    "PATH", "HOME", "USER", "LANG", "LC_ALL", 
    "PYTHONPATH", "TERM", "SHELL", "PWD"
])
child_env = {k: v for k, v in os.environ.items() 
             if k in _ALLOWED_ENV_VARS}
# Explicitly load only non-secret values

Fix 4: API Server Authentication (V-009)

# CURRENT CODE (gateway/platforms/api_server.py ~line 360-361)
if not self._api_key:
    return None  # No key configured — allow all

# SECURE FIX
if not self._api_key:
    logger.error("API server started without authentication")
    return web.json_response(
        {"error": "Server misconfigured - auth required"},
        status=500
    )

Fix 5: CORS Configuration (V-008)

# CURRENT CODE (gateway/platforms/api_server.py ~lines 324-328)
if "*" in self._cors_origins:
    headers["Access-Control-Allow-Origin"] = "*"

# SECURE FIX - Never allow wildcard with credentials
if "*" in self._cors_origins:
    logger.warning("Wildcard CORS not allowed with credentials")
    return None

Fix 6: OAuth State Validation (V-014)

# CURRENT CODE (tools/mcp_oauth.py ~line 186)
code, state = await _wait_for_callback()

# SECURE FIX
stored_state = get_stored_state()
if state != stored_state:
    raise SecurityError("OAuth state mismatch - possible CSRF attack")

Fix 7: Docker Volume Mount Validation (V-012)

# CURRENT CODE (tools/environments/docker.py ~line 267)
volume_args.extend(["-v", vol])

# SECURE FIX
_BLOCKED_PATHS = ['/var/run/docker.sock', '/proc', '/sys', ...]
if any(blocked in vol for blocked in _BLOCKED_PATHS):
    raise SecurityError(f"Volume mount {vol} not allowed")
volume_args.extend(["-v", vol])

Fix 8: Debug Output Redaction (V-027)

# Add to all debug logging
from agent.redact import redact_sensitive_text
logger.debug(redact_sensitive_text(debug_message))

Fix 9: Input Length Validation

# Add to all tool entry points
MAX_INPUT_LENGTH = 10000
if len(user_input) > MAX_INPUT_LENGTH:
    raise ValueError(f"Input exceeds maximum length of {MAX_INPUT_LENGTH}")

Fix 10: Session ID Entropy

# CURRENT CODE - uses uuid4
import uuid
session_id = str(uuid.uuid4())

# SECURE FIX - use secrets module
import secrets
session_id = secrets.token_urlsafe(32)
