🚨 Urgent Security Alert: Critical Vulnerabilities Found!

Hey guys! This is a heads-up about some serious security issues we found in your application. We're talking about potential remote code execution, command injection, and data integrity risks – stuff that could let bad actors wreak havoc. Let's dive in and get these fixed ASAP!

🛡️ Watchman Security Scan Report

  • Scan Date: 2025-10-10 15:02:57 UTC
  • Branch: main
  • Commit: manual_s
  • Analyzer: Claude AI + Semgrep

📝 Executive Summary

The application faces several critical security vulnerabilities. These flaws could allow attackers to execute arbitrary commands, inject malicious code, and compromise the system's data. Addressing these issues promptly is essential to protect your application and its users. We are going to have a look on each of these issues and what we can do to fix them to make the system secure.

🚨 Critical Issues

1. 🔴 OS Command Injection via Subprocess

  • File: app/api.py
  • Line: 11
  • Severity: CRITICAL

Description:

Okay, listen up! In app/api.py, line 11, we've got a real problem. The code's using subprocess.call(shell=True). The shell=True part is the kicker, because it lets an attacker run whatever they want on your server. Imagine someone sneaking in a command and taking control – that's what we're trying to prevent here. This vulnerability is all about command injection; bad guys can inject their commands and make the system do things it shouldn't. It's like leaving the back door unlocked!

Business Impact:

So, what's the worst that could happen? An attacker could execute system commands without authorization, potentially leading to a full-blown server compromise. Think of it: unauthorized access, data theft, and all sorts of headaches. This could be a complete disaster and cause all sorts of issues that no one wants to happen.

Recommended Fix:

Here’s the fix: switch to subprocess.call with shell=False. This will treat the user input as a string and not allow any command injections.

Replace with: subprocess.call(["ping", "-c", "1", user_input], shell=False)

Compliance Standards:

  • OWASP A03:2021
  • CWE-78
  • NIST SP 800-53 SI-10

2. 🟠 Disabled SSL Certificate Verification

  • File: app/utils.py
  • Line: 7
  • Severity: HIGH

Description:

Alright, moving on to app/utils.py, line 7. The code is skipping SSL certificate verification. This is like not checking the ID of someone you're letting into the house. It exposes you to a man-in-the-middle attack, where an attacker can eavesdrop on your network traffic or even change the data being sent back and forth.

Business Impact:

Without proper SSL verification, your application is vulnerable to a bunch of network-level attacks, potential data interception, and a complete compromise of the transport layer security. This means your sensitive data could be exposed, and your users' trust could be shattered.

Recommended Fix:

Easy fix: get rid of verify=False. If you're dealing with custom certificates, you'll want to manage them properly, or, at least, use a specific CA bundle. Ensure that you're verifying certificates to prevent any sort of attacks.

Remove verify=False, use proper certificate management or provide specific CA bundle

Compliance Standards:

  • OWASP A07:2021
  • PCI-DSS 4.1
  • NIST SP 800-52

3. 🔴 Unsafe Deserialization with Pickle

  • File: app/api.py
  • Line: 22
  • Severity: CRITICAL

Description:

Now, let's look at app/api.py line 22. We found unsafe deserialization with pickle. The pickle.loads() function takes serialized data and turns it back into objects. The problem is, if the data comes from an untrusted source, it can be used to execute arbitrary Python code. It's like opening a package and not knowing if there’s a bomb inside. Unsafe Deserialization is dangerous because it allows malicious code to be run during the deserialization process.

Business Impact:

This can be a complete application runtime takeover. Attackers can use this to run any Python code they want during deserialization, completely compromising the application. They can take complete control, stealing data, and causing serious damage.

Recommended Fix:

To fix this: Use json.loads() which is much safer, or, if you have to use pickle, implement strict input validation. Make sure that you are only deserializing data from trusted sources, and never from data that is not validated.

Use json.loads() or implement strict input validation before deserialization

Compliance Standards:

  • OWASP A08:2021
  • CWE-502
  • SANS Top 25 Insecure Deserialization

🔧 Recommended Actions

Here’s what we need to do, step-by-step:

  1. Patch Immediately: Fix the subprocess and requests usage in the current codebase.
  2. Modernize Hashing: Replace all MD5 password hashing with a modern, secure algorithm like Argon2 or bcrypt.
  3. Input Validation: Validate all user-supplied data. Don't trust anything that comes from outside!
  4. Eliminate Dangerous Functions: Remove any use of eval() and pickle throughout your application.
  5. Team Training: Provide comprehensive security training for your development team. Make sure everyone understands the risks and how to avoid them.
