  • Attack Vector Name: Prototype Pollution via JSON Parsing
  • Description: An attacker crafts a malicious Lottie animation JSON file designed to exploit prototype pollution vulnerabilities in the JavaScript parsing logic of lottie-react-native or the application. By manipulating the JavaScript prototype chain, the attacker might be able to:
    • Bypass application logic.
    • Cause Denial of Service.
    • In some scenarios, potentially achieve Remote Code Execution if combined with other vulnerabilities or application weaknesses.
  • Risk Assessment:
    • Likelihood: Medium
    • Impact: Medium
    • Effort: Medium
    • Skill Level: Medium
    • Detection Difficulty: Medium
  • Mitigation Strategies:
    • Input Validation & Sanitization: While directly sanitizing complex JSON is difficult, ensure robust parsing and error handling.
    • Regular Updates: Keep lottie-react-native updated to benefit from security patches.
    • Security Testing: Conduct security testing specifically for prototype pollution vulnerabilities when handling animation JSON.
    • Consider using secure JSON parsing libraries: If applicable, explore using JSON parsing libraries known for their security and resistance to prototype pollution.
  • Attack Vector Name: CPU Exhaustion via Complex Animation Rendering
  • Description: An attacker provides an intentionally complex Lottie animation file that, when rendered by lottie-react-native, consumes excessive CPU resources. This can lead to:
    • Application slowdown and unresponsiveness.
    • Temporary unavailability of the application.
    • Battery drain on mobile devices.
  • Risk Assessment:
    • Likelihood: Medium
    • Impact: Medium
    • Effort: Low
    • Skill Level: Low
    • Detection Difficulty: Easy
  • Mitigation Strategies:
    • Resource Limits: Implement safeguards to limit resources used by animation rendering.
    • Animation Complexity Limits: If feasible, analyze animation complexity and reject overly complex animations.
    • Timeouts: Set timeouts for animation rendering to prevent indefinite CPU usage.
    • Rate Limiting (Remote Animations): If loading remote animations, implement rate limiting.
  • Attack Vector Name: Memory Exhaustion via Large Animation Assets
  • Description: An attacker provides excessively large Lottie animation files. Loading and rendering these large files can consume significant memory, leading to:
    • Application crashes due to out-of-memory errors.
    • Application instability and performance degradation.
    • Memory leaks if not handled properly.
  • Risk Assessment:
    • Likelihood: Medium
    • Impact: Medium
    • Effort: Low
    • Skill Level: Low
    • Detection Difficulty: Easy
  • Mitigation Strategies:
    • Resource Limits: Implement memory monitoring and handle out-of-memory situations gracefully.
    • Animation Size Limits: Impose limits on the size of animation files that can be loaded.
    • Streaming/Progressive Loading: If possible, implement streaming or progressive loading of animations to reduce memory footprint.
  • Attack Vector Name: Exploitation of Known Vulnerabilities (CVEs)
  • Description: lottie-react-native or its underlying dependencies (native animation libraries) might have publicly disclosed vulnerabilities (CVEs). If the application uses a vulnerable version, an attacker can exploit these known vulnerabilities to:
    • Cause Denial of Service.
    • Achieve Remote Code Execution.
    • Gain unauthorized access or control.
  • Risk Assessment:
    • Likelihood: Medium (depends on update practices)
    • Impact: High
    • Effort: Low (exploits often publicly available)
    • Skill Level: Low to Medium
    • Detection Difficulty: Easy
  • Mitigation Strategies:
    • Dependency Management: Use a robust dependency management system.
    • Regular Updates: Keep lottie-react-native and dependencies updated.
    • Vulnerability Scanning: Integrate vulnerability scanning into the development pipeline.
    • Security Monitoring: Subscribe to security advisories for lottie-react-native and its ecosystem.
  • Attack Vector Name: Exploitation of Vulnerabilities in Transitive Dependencies
  • Description: lottie-react-native relies on other libraries (dependencies), which in turn might have their own dependencies (transitive dependencies). Vulnerabilities in these transitive dependencies can be exploited to compromise the application, similar to exploiting vulnerabilities in lottie-react-native itself.
  • Risk Assessment:
    • Likelihood: Low to Medium
    • Impact: High
    • Effort: Medium
    • Skill Level: Medium
    • Detection Difficulty: Medium
  • Mitigation Strategies:
    • Dependency Management: Thoroughly manage and audit all dependencies, including transitive ones.
    • Vulnerability Scanning: Ensure vulnerability scanning tools also check transitive dependencies.
    • Dependency Tree Analysis: Analyze the dependency tree to understand transitive dependencies and their potential risks.
  • Attack Vector Name: Insecure Remote Animation Loading
  • Description: If the application loads Lottie animations from remote URLs without proper validation, an attacker can control the remote server and serve malicious animation files. This can lead to:
    • Denial of Service (via resource exhaustion or malicious animation logic).
    • Potentially code execution if combined with other vulnerabilities.
    • Information disclosure or other application compromises depending on the malicious animation's design and application logic.
  • Risk Assessment:
    • Likelihood: Medium to High
    • Impact: Medium to High
    • Effort: Low
    • Skill Level: Low
    • Detection Difficulty: Medium
  • Mitigation Strategies:
    • Secure Animation Sources: Load animations only from trusted and controlled sources.
    • URL Validation: Implement strict URL validation to ensure URLs point to expected domains and protocols.
    • Content Security Policy (CSP) (Web Context): If using Lottie in web views, use CSP to restrict animation sources.
  • Attack Vector Name: Path Traversal in Local Animation Loading
  • Description: If the application allows loading local animation files based on user input without proper sanitization, an attacker can use path traversal techniques (e.g., ../../malicious.json) to load malicious animation files from arbitrary locations on the device's file system.
  • Risk Assessment:
    • Likelihood: Low to Medium
    • Impact: Medium to High
    • Effort: Low
    • Skill Level: Low
    • Detection Difficulty: Medium
  • Mitigation Strategies:
    • Input Validation: Sanitize and validate user-provided file paths to prevent path traversal.
    • Principle of Least Privilege: Limit the application's file system access to only necessary directories.
    • Secure File Handling APIs: Use secure file handling APIs that prevent path traversal vulnerabilities.
  • Attack Vector Name: Insecure Handling of User-Provided Animation Files
  • Description: If the application allows users to upload or provide Lottie animation files directly, attackers can upload malicious files. This can lead to:
    • Denial of Service (resource exhaustion, malicious animation logic).
    • Potentially code execution if combined with other vulnerabilities.
    • Social engineering attacks if malicious animations are shared with other users.
  • Risk Assessment:
    • Likelihood: Medium
    • Impact: Medium to High
    • Effort: Low
    • Skill Level: Low
    • Detection Difficulty: Medium
  • Mitigation Strategies:
    • File Type Validation: Validate file types to ensure only expected animation formats are accepted.
    • Content Scanning: Scan uploaded animation files for known malicious patterns or excessive complexity (if feasible).
    • Sandboxing: Render user-provided animations in a sandboxed environment to limit potential damage.
    • User Awareness: Educate users about the risks of opening animations from untrusted sources (if animations are shared).
  • Attack Vector Name: Exploitation of Improper Error Handling
  • Description: If the application does not handle errors from lottie-react-native properly (e.g., during animation loading or rendering), attackers can trigger errors by providing malformed or malicious animations. Poor error handling can:
    • Reveal sensitive information in error messages (information disclosure).
    • Lead to unexpected application states and potentially further vulnerabilities.
    • Cause minor application disruptions.
  • Risk Assessment:
    • Likelihood: Medium
    • Impact: Low to Medium
    • Effort: Low
    • Skill Level: Low
    • Detection Difficulty: Easy
  • Mitigation Strategies:
    • Graceful Error Handling: Implement robust error handling for animation loading and rendering.
    • Avoid Sensitive Information in Error Messages: Ensure error messages do not reveal sensitive internal information.
    • Logging and Monitoring: Log errors for debugging and monitoring, but ensure logs are securely stored.
