    • SSRF: Server-Side Request Forgery, attacker can make requests to internal resources or external systems from the server.
    • Data Exfiltration: Sensitive data breach by extracting data through template injection.
  • Mitigation:
    • Secure Templating Practices: Avoid using user-controlled input directly in templates.
    • Input Sanitization and Output Encoding: Sanitize user input and properly encode output for the specific template engine being used.
    • Use Parameterized Templates: Utilize parameterized templates or safer templating mechanisms that separate code from data.

Attack Tree Path: Insecure Content Handling (if Iris mishandles content types) -> Cross-Site Scripting (XSS) (via content type manipulation) (HIGH RISK PATH)

  • Attack Vector: If Iris mishandles content types or allows manipulation of content types, attackers can craft requests to trigger unexpected content processing, potentially leading to XSS vulnerabilities.

Attack Tree Path: Session Fixation (HIGH RISK PATH) -> Account Takeover (CRITICAL NODE, HIGH RISK PATH)

  • Attack Vector: If Iris session management is vulnerable to session fixation, attackers can force a user to use a pre-determined session ID, allowing the attacker to hijack the session after the user authenticates.
  • Impact: Account takeover, unauthorized access to user accounts.
  • Mitigation:
    • Session Fixation Prevention: Ensure Iris session management framework prevents session fixation by regenerating session IDs upon successful login.
    • Secure Session Configuration: Configure session management securely, including using HTTPS and secure session ID generation.

Attack Tree Path: Session Hijacking (if session IDs are predictable or insecurely transmitted) (HIGH RISK PATH) -> Account Takeover (CRITICAL NODE, HIGH RISK PATH)

  • Attack Vector: If Iris session IDs are predictable or transmitted insecurely (e.g., over HTTP), attackers can obtain a valid session ID of a legitimate user and hijack their session.
  • Impact: Account takeover, unauthorized access to user accounts.
  • Mitigation:
    • Strong Session ID Generation: Ensure Iris uses cryptographically strong and unpredictable session ID generation.
    • HTTPS Enforcement: Enforce HTTPS for all session-related communication to prevent session hijacking via network sniffing.

Attack Tree Path: Insecure Session Storage (if Iris stores sessions insecurely by default) -> Session Data Leakage (CRITICAL NODE, HIGH RISK PATH) / Privilege Escalation (CRITICAL NODE, HIGH RISK PATH)

  • Attack Vector: If Iris stores session data insecurely by default (e.g., in plaintext files accessible to unauthorized users), attackers can access session storage to retrieve sensitive session data, potentially leading to data leakage or privilege escalation.
  • Impact:
    • Session Data Leakage: Exposure of sensitive session data, including user information, session tokens, etc.
    • Privilege Escalation: Gaining elevated privileges if session data contains privilege information.
  • Mitigation:

  • Attack Vector: Lack of input validation on WebSocket messages can allow attackers to inject malicious messages. If these messages are rendered on client-side without escaping, it can lead to XSS. If server-side processing of messages is insecure, it can lead to command injection.
  • Impact:
    • XSS (via WebSocket): Client-side compromise, session hijacking, malicious actions on behalf of the user.
    • Command Injection (via WebSocket): Server compromise, RCE, attacker can execute arbitrary commands on the server.
  • Mitigation:
    • Input Validation on WebSocket Messages: Strictly validate and sanitize all data received via WebSocket messages on both client and server sides.
