  • Likelihood: Medium - Sentry features, if not carefully managed, can be susceptible to abuse.
  • Impact: Medium to High - Can lead to data injection, information disclosure, or resource exhaustion.
  • Effort: Low to Medium - Often relies on exploiting application-side weaknesses or misconfigurations.
  • Skill Level: Low to Medium - Basic web application security knowledge.
  • Detection Difficulty: Medium - Requires monitoring Sentry data and usage patterns.

Attack Tree Path: [HIGH-RISK PATH] [2.1] Data Injection/Poisoning via Sentry

  • Impact: Medium - Data corruption in Sentry, misleading error analysis, potential for denial of service if used for spamming.
  • Effort: Low - Exploiting existing vulnerabilities in the application.
  • Skill Level: Low to Medium - Basic web application exploitation skills.
  • Detection Difficulty: Medium - Depends on monitoring of Sentry data and error patterns.

Attack Tree Path: [HIGH-RISK PATH] [2.1.1] Inject Malicious Data through Application Errors

  • Description: Attackers exploit vulnerabilities in the application to trigger errors that contain malicious payloads. Sentry captures these errors, effectively injecting malicious data into the Sentry platform.

  • Impact: Medium
  • Effort: Low
  • Skill Level: Low-Medium
  • Detection Difficulty: Medium
  • Actionable Insight: Input validation, sanitization. Rate limiting.

  • Likelihood: High - Developers often unintentionally log sensitive data in errors.
  • Impact: Medium to High - Exposure of sensitive data, PII, secrets, internal paths.
  • Effort: Low - No direct attack on Sentry needed, relies on developer errors.
  • Skill Level: Low - Attacker just needs to trigger errors and access Sentry.
  • Detection Difficulty: Low to Medium - Reviewing Sentry error logs, data loss prevention tools.

Attack Tree Path: [HIGH-RISK PATH] [2.3.1] Leak Sensitive Data in Error Messages Captured by Sentry

  • Description: Developers inadvertently include sensitive data (like API keys, passwords, PII, internal file paths) in error messages that are then sent to Sentry. An attacker gaining access to Sentry can then view these error messages and extract the sensitive information.
  • Likelihood: High
  • Impact: Medium-High
  • Effort: Low
  • Skill Level: Low
  • Detection Difficulty: Low-Medium
  • Actionable Insight: Careful error handling. Sanitize error messages. Avoid logging sensitive data. Data scrubbing.

Attack Tree Path: [HIGH-RISK PATH] [2.3.2] Access Sensitive Data Stored in Sentry Platform

  • Description: Attackers directly target the Sentry platform to access sensitive data that is stored within it, such as error details, user information, or project settings.

Attack Tree Path: [HIGH-RISK PATH] [2.3.2.1] Compromise Sentry User Accounts

  • Description: Attackers compromise legitimate Sentry user accounts through methods like phishing, credential stuffing, or password reuse. Once inside, they can access all data and settings within Sentry that the compromised user has permissions for, potentially including sensitive error information.
  • Likelihood: Medium
  • Impact: High
  • Effort: Low-Medium
  • Skill Level: Low-Medium
  • Detection Difficulty: Medium
  • Actionable Insight: Strong passwords, MFA. Audit user access. Account lockout.

Attack Tree Path: [HIGH-RISK PATH] [3.0] Compromise Sentry Infrastructure (Self-Hosted Sentry)

  • Description: For self-hosted Sentry instances, attackers target the underlying infrastructure (servers, databases, network) to compromise the Sentry platform and gain access to its data and functionality.
  • Likelihood: Medium - Infrastructure vulnerabilities and misconfigurations are common attack vectors.
  • Impact: High to Critical - Full compromise of Sentry infrastructure, data breach, potential for lateral movement.
  • Effort: Medium - Requires infrastructure exploitation skills.
  • Skill Level: Medium to High - System administration, networking, and security expertise.
  • Detection Difficulty: Medium - Requires robust infrastructure security monitoring.

Attack Tree Path: [HIGH-RISK PATH] [3.1] Exploit Vulnerabilities in Underlying Infrastructure

  • Description: Attackers exploit known or zero-day vulnerabilities in the operating system, database, containerization platform, or network infrastructure that hosts the self-hosted Sentry instance.

Attack Tree Path: [HIGH-RISK PATH] [3.1.1] Exploit OS Vulnerabilities

  • Description: Attackers exploit vulnerabilities in the operating system of the server hosting Sentry. This could allow them to gain root access, compromise the Sentry installation, and potentially pivot to other systems.
  • Likelihood: Medium
  • Impact: Critical
  • Effort: Low-Medium
  • Skill Level: Medium
  • Detection Difficulty: Medium
  • Actionable Insight: Patch OS. Harden server.

Attack Tree Path: [HIGH-RISK PATH] [3.1.4] Network Security Vulnerabilities

  • Description: Attackers exploit network misconfigurations or vulnerabilities to gain unauthorized access to the network segment where the Sentry server is located. This could allow them to intercept traffic, perform man-in-the-middle attacks, or directly access the Sentry server if it's exposed.
