RCE Weak/Default Auth Bypass Exposed
[CRITICAL] Credentials (Misconfig) Sensitive
-> HIGH RISK -> [CRITICAL] [CRITICAL] Data [CRITICAL]
Attack Tree Path: Exploit RailsAdmin Vulnerabilities -> RCE
- Description: An attacker exploits a vulnerability in the RailsAdmin code that allows them to execute arbitrary code on the server. This is the most severe type of vulnerability.
- Likelihood: Low (if regularly updated), Medium (if updates are delayed), High (if significantly outdated)
- Impact: Very High (complete server compromise, data breach, data manipulation, denial of service)
- Effort: High to Very High (finding and exploiting a 0-day is extremely difficult; exploiting a known vulnerability depends on patch availability)
- Skill Level: Advanced to Expert
- Detection Difficulty: Medium to Hard (requires robust logging, intrusion detection systems, and potentially specialized security expertise)
- Mitigation:
- Keep RailsAdmin and all its dependencies updated to the latest versions.
- Implement strict input validation and sanitization for all user-provided data, even within RailsAdmin's custom fields or actions.
- Conduct regular security audits and penetration testing, specifically targeting potential RCE vulnerabilities.
- Employ a Web Application Firewall (WAF) to help detect and block malicious requests.
- Use a principle of least privilege for the web server process, limiting its access to only necessary resources.
Attack Tree Path: Bypass Authentication/Authorization -> Weak/Default Credentials
- Description: An attacker gains administrative access by guessing or using default credentials that have not been changed.
- Likelihood: Medium (surprisingly common, especially in development, staging, or poorly maintained environments)
- Impact: High (full administrative access, data breach, data manipulation, denial of service)
- Effort: Very Low (brute-force or dictionary attacks are simple to execute)
- Skill Level: Script Kiddie to Beginner
- Detection Difficulty: Easy (repeated failed login attempts are easily detectable with basic logging)
- Mitigation:
- Enforce strong password policies (minimum length, complexity requirements, regular password changes).
- Implement multi-factor authentication (MFA) for all RailsAdmin users.
- Never use default credentials in production environments. Change default passwords immediately after installation.
- Monitor login attempts and lock accounts after a certain number of failed attempts.
Attack Tree Path: Bypass Authentication/Authorization -> Authentication Bypass (Misconfig)
- Description: A configuration error in RailsAdmin (e.g., in the
config/initializers/rails_admin.rb
file) effectively disables authentication, allowing anyone to access the administrative interface.- Likelihood: Low (requires a significant and specific configuration mistake)
- Impact: High (full administrative access, data breach, data manipulation, denial of service)
- Effort: Low (if the misconfiguration is present, exploitation is trivial)
- Skill Level: Beginner
- Detection Difficulty: Easy (once the misconfiguration is discovered, it's obvious; however, finding the misconfiguration might require careful review)
- Mitigation:
- Thoroughly review and test the
authenticate_with
block in the RailsAdmin initializer. Ensure it correctly implements the intended authentication logic. - Use a configuration management tool to ensure consistent and secure configurations across environments.
- Conduct regular security audits and code reviews, specifically focusing on the RailsAdmin configuration.
- Thoroughly review and test the
Attack Tree Path: Leverage Misconfiguration -> Exposed Sensitive Data
- Description: RailsAdmin is misconfigured to display sensitive data (e.g., password hashes, API keys, database credentials) directly in the interface.
- Likelihood: Low (requires a significant oversight in configuration)
- Impact: High (depending on the data exposed; passwords or API keys would be Very High, leading to further compromise)
- Effort: Very Low (simply viewing the RailsAdmin interface)
- Skill Level: Script Kiddie
- Detection Difficulty: Very Easy (the data is directly visible)
- Mitigation:
- Carefully review the RailsAdmin configuration and model configurations. Ensure that sensitive fields are not displayed.
- Use appropriate field types (e.g.,
password
instead ofstring
for passwords). - Customize the display of fields to redact or hide sensitive information.
- Store sensitive data securely (e.g., using environment variables, a secrets management system) and never directly in the database or code.
- Conduct regular security audits to identify and address any exposed sensitive data.
