Attack Tree Path: Compromise Application via Clouddriver [CRITICAL NODE]

  • Compromise Application via Clouddriver [CRITICAL NODE]:
    • This is the root goal and represents the ultimate objective of the attacker. Success here means the attacker has compromised the application through Clouddriver.

Attack Tree Path: Exploit Clouddriver API Vulnerabilities [CRITICAL NODE]

  • Exploit Clouddriver API Vulnerabilities [CRITICAL NODE]:
    • This path focuses on exploiting weaknesses in the Clouddriver API itself. A successful attack here grants the attacker control over Clouddriver functionalities and potentially the underlying infrastructure.

Attack Tree Path: 1.1. Authentication/Authorization Bypass [HIGH-RISK PATH] [CRITICAL NODE]

  • 1.1. Authentication/Authorization Bypass [HIGH-RISK PATH] [CRITICAL NODE]: * Attackers aim to circumvent authentication mechanisms to gain unauthorized access to the API or bypass authorization checks to perform actions beyond their intended privileges.

Attack Tree Path: 1.1.1. Exploit Weak Authentication Mechanisms [HIGH-RISK PATH]

  • 1.1.1. Exploit Weak Authentication Mechanisms [HIGH-RISK PATH]: * This involves exploiting weak or default credentials, insecure authentication protocols, or vulnerabilities in the authentication process itself to gain unauthorized API access.

Attack Tree Path: 1.1.2. Authorization Flaws leading to Privilege Escalation [HIGH-RISK PATH]

  • 1.1.2. Authorization Flaws leading to Privilege Escalation [HIGH-RISK PATH]: * Attackers exploit flaws in the authorization logic to elevate their privileges, allowing them to perform actions they are not supposed to, potentially gaining administrative control.

Attack Tree Path: 1.1.3. API Endpoint Vulnerabilities (e.g., Injection, Deserialization) [HIGH-RISK PATH] [CRITICAL NODE]

  • 1.1.3. API Endpoint Vulnerabilities (e.g., Injection, Deserialization) [HIGH-RISK PATH] [CRITICAL NODE]: * This path targets common web application vulnerabilities within the API endpoints of Clouddriver.

Attack Tree Path: 1.1.3.1. Injection Attacks (e.g., Command Injection, Server-Side Request Forgery - SSRF) [HIGH-RISK PATH]

  • 1.1.3.1. Injection Attacks (e.g., Command Injection, Server-Side Request Forgery - SSRF) [HIGH-RISK PATH]: * Attackers inject malicious code or commands into API requests, exploiting insufficient input validation to execute arbitrary commands on the server or perform actions like SSRF.

Attack Tree Path: 1.1.3.3. API Logic Flaws [HIGH-RISK PATH]

  • 1.1.3.3. API Logic Flaws [HIGH-RISK PATH]: * Attackers exploit flaws in the intended logic of the API, manipulating API calls in unexpected ways to achieve unauthorized actions or data manipulation.

Attack Tree Path: 2. Compromise Clouddriver's Cloud Provider Credentials [HIGH-RISK PATH] [CRITICAL NODE]

  • 2. Compromise Clouddriver's Cloud Provider Credentials [HIGH-RISK PATH] [CRITICAL NODE]: * This path targets the credentials Clouddriver uses to interact with cloud providers. Compromising these credentials grants broad access to cloud resources.

Attack Tree Path: 2.1. Credential Theft from Clouddriver Process/Memory [CRITICAL NODE]

  • 2.1. Credential Theft from Clouddriver Process/Memory [CRITICAL NODE]: * Attackers attempt to extract cloud provider credentials directly from the running Clouddriver process memory, potentially using memory dumping techniques.

Attack Tree Path: 2.2. Credential Theft from Configuration Files/Storage [HIGH-RISK PATH] [CRITICAL NODE]

  • 2.2. Credential Theft from Configuration Files/Storage [HIGH-RISK PATH] [CRITICAL NODE]: * Attackers target insecure storage locations where cloud provider credentials might be stored, such as configuration files or accessible storage without proper access controls.

Attack Tree Path: 2.3. Exploiting Vulnerabilities to Access Credentials [CRITICAL NODE]

  • 2.3. Exploiting Vulnerabilities to Access Credentials [CRITICAL NODE]: * This involves using vulnerabilities within Clouddriver to gain access to the locations where credentials are stored.

Attack Tree Path: 2.3.1. Code Vulnerabilities leading to Credential Exposure [CRITICAL NODE]

  • 2.3.1. Code Vulnerabilities leading to Credential Exposure [CRITICAL NODE]: * Attackers exploit code vulnerabilities in Clouddriver that could lead to the exposure of stored cloud provider credentials.

Attack Tree Path: 2.3.2. Misconfiguration leading to Credential Exposure [HIGH-RISK PATH] [CRITICAL NODE]

  • 2.3.2. Misconfiguration leading to Credential Exposure [HIGH-RISK PATH] [CRITICAL NODE]: * Attackers exploit misconfigurations in Clouddriver that inadvertently expose cloud provider credentials, such as overly permissive access controls or insecure settings.

Attack Tree Path: 2.4. Man-in-the-Middle (MitM) Attacks on Credential Retrieval [CRITICAL NODE]

  • 2.4. Man-in-the-Middle (MitM) Attacks on Credential Retrieval [CRITICAL NODE]: * Attackers intercept communication channels during the retrieval of cloud provider credentials, aiming to steal them in transit if communication is not properly secured (e.g., using HTTPS and mTLS).

Attack Tree Path: 3. Exploit Clouddriver Code Vulnerabilities (General) [HIGH-RISK PATH] [CRITICAL NODE]

  • 3. Exploit Clouddriver Code Vulnerabilities (General) [HIGH-RISK PATH] [CRITICAL NODE]:
    • This path focuses on exploiting general code vulnerabilities within Clouddriver itself, beyond API-specific vulnerabilities.

Attack Tree Path: 3.1. Known Vulnerabilities in Clouddriver or Dependencies [HIGH-RISK PATH]

  • 3.1. Known Vulnerabilities in Clouddriver or Dependencies [HIGH-RISK PATH]: * Attackers exploit publicly known vulnerabilities in Clouddriver or its dependencies for which patches may be available but not yet applied.

Attack Tree Path: 4. Misconfiguration of Clouddriver [HIGH-RISK PATH] [CRITICAL NODE]

  • 4. Misconfiguration of Clouddriver [HIGH-RISK PATH] [CRITICAL NODE]:
    • This path focuses on exploiting vulnerabilities arising from insecure configurations of Clouddriver.

Attack Tree Path: 4.1. Insecure API Exposure [HIGH-RISK PATH]

  • 4.1. Insecure API Exposure [HIGH-RISK PATH]: * Attackers exploit situations where the Clouddriver API is exposed publicly without proper authentication or authorization, significantly increasing the attack surface.

Attack Tree Path: 4.2. Weak Authentication/Authorization Configuration [HIGH-RISK PATH]

  • 4.2. Weak Authentication/Authorization Configuration [HIGH-RISK PATH]: * Attackers exploit weak or default authentication settings or insecure authorization configurations, making it easier to bypass security controls.

Attack Tree Path: 4.3. Overly Permissive Access Control [HIGH-RISK PATH]

  • 4.3. Overly Permissive Access Control [HIGH-RISK PATH]: * Attackers exploit overly permissive access control policies that grant users or services more privileges than necessary, allowing for unauthorized actions.
