CVE-2024-50645

9.8 CRITICAL

📋 TL;DR

MallChat v1.0-SNAPSHOT has an authentication bypass vulnerability that allows attackers to access APIs without any authentication token. This affects all deployments running the vulnerable version, potentially exposing sensitive data and functionality to unauthorized users.

💻 Affected Systems

Products:
  • MallChat
Versions: v1.0-SNAPSHOT
Operating Systems: All platforms running the vulnerable software
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments of MallChat v1.0-SNAPSHOT are vulnerable by default.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise where attackers can access all API endpoints, manipulate data, escalate privileges, and potentially execute arbitrary code.

🟠

Likely Case

Unauthorized access to sensitive user data, chat messages, and administrative functions leading to data breach and service disruption.

🟢

If Mitigated

Limited impact if proper network segmentation, API rate limiting, and additional authentication layers are in place.

🌐 Internet-Facing: HIGH - Internet-facing instances are directly exploitable without authentication.
🏢 Internal Only: HIGH - Internal instances are also vulnerable to insider threats or compromised internal systems.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

The vulnerability requires no authentication and is trivial to exploit by sending requests without tokens.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not available

Vendor Advisory: Not available

Restart Required: No

Instructions:

No official patch available. Consider upgrading to a newer version if available or implementing workarounds.

🔧 Temporary Workarounds

Implement API Gateway Authentication

all

Add authentication layer at API gateway or reverse proxy level

# Configure nginx with authentication
location /api/ {
    auth_request /auth;
    proxy_pass http://mallchat_backend;
}

Network Segmentation

linux

Restrict access to MallChat API endpoints using firewall rules

# Example iptables rule to restrict API access
iptables -A INPUT -p tcp --dport 8080 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP

🧯 If You Can't Patch

  • Implement Web Application Firewall (WAF) rules to block unauthenticated API requests
  • Monitor and alert on unusual API access patterns and failed authentication attempts

🔍 How to Verify

Check if Vulnerable:

Send API request without authentication token to any protected endpoint. If request succeeds, system is vulnerable.

Check Version:

Check application configuration or deployment manifest for version information

Verify Fix Applied:

Attempt same unauthenticated API request - should receive 401/403 error.

📡 Detection & Monitoring

Log Indicators:

  • API requests without authentication headers
  • Successful API calls from unauthenticated sources
  • Unusual API access patterns

Network Indicators:

  • HTTP requests to API endpoints without Authorization headers
  • Unusual traffic volume to API endpoints

SIEM Query:

source="mallchat" AND (http_method="POST" OR http_method="GET") AND NOT auth_token=* AND response_code=200
