Mitigation Strategies Analysis for wox-launcher/wox

Mitigation Strategy: Plugin Sandboxing and Isolation (Wox-Focused)

  • Description:

    1. Investigate Wox Isolation Features: Thoroughly research the Wox documentation and codebase to identify any built-in mechanisms for plugin isolation. This could include process separation, permission restrictions, or API limitations imposed by Wox on plugins.
    2. Leverage Wox Isolation Capabilities: If Wox provides any isolation features, configure and utilize them to the maximum extent possible. This might involve setting specific configuration options or using Wox APIs in a way that enforces isolation.
    3. Request Isolation Features from Wox Project: If Wox lacks sufficient isolation features, consider contributing to the Wox open-source project by proposing and implementing enhanced plugin sandboxing and isolation mechanisms.
    4. Document Wox Isolation Limitations: Clearly document the limitations of Wox's plugin isolation capabilities for developers and users, highlighting any remaining risks.

    • Threats Mitigated:

      • Plugin Privilege Escalation (High Severity): Limits the ability of a compromised plugin to gain elevated privileges within the Wox environment if Wox enforces isolation.
      • Cross-Plugin Interference (Medium Severity): Prevents malicious or buggy plugins from interfering with other plugins or the core Wox application if Wox provides process or resource separation.
      • System-Wide Compromise from Plugin (High Severity): Reduces the impact of a compromised plugin from affecting the entire system to the extent that Wox's isolation mechanisms are effective.

    • Impact: Impact is directly tied to the effectiveness of Wox's isolation features (if any). Potential for High Reduction if Wox offers robust isolation, otherwise limited.

    • Currently Implemented: Unknown. Requires investigation of Wox codebase and documentation to determine existing isolation features.

    • Missing Implementation: Potentially missing if Wox lacks built-in isolation. Implementation would involve modifying Wox core or plugin framework.

Mitigation Strategy: Plugin Permission Management (Wox-Focused)

  • Description:

    1. Analyze Wox Plugin API and Capabilities: Examine the Wox plugin API to understand what system resources and functionalities plugins can access through Wox.
    2. Design Wox-Level Permission Control (if feasible): If Wox's architecture allows, design and implement a permission control system within Wox itself. This could involve defining permission levels, requiring plugins to declare permissions, and providing a UI for users to manage plugin permissions within the Wox application.
    3. Restrict Wox Plugin API Access (if necessary): If direct permission control within Wox is not feasible, consider modifying the Wox plugin API to restrict access to sensitive system functionalities by default. Require explicit actions or configurations for plugins to access more privileged APIs.
    4. Document Wox Plugin Permissions: Clearly document the permissions that Wox plugins inherently have and any limitations or controls that are in place.

    • Threats Mitigated:

      • Data Exfiltration by Plugins (High Severity): Prevents plugins from accessing and exfiltrating sensitive data through Wox APIs if Wox enforces permission controls.
      • Unauthorized System Access by Plugins (Medium Severity): Limits plugins' ability to perform unauthorized actions on the system via Wox functionalities if Wox restricts API access.
      • Privacy Violations by Plugins (Medium Severity): Reduces the risk of plugins collecting and misusing user data through Wox interfaces if Wox manages permissions.

    • Impact: Impact is dependent on Wox's architecture and the feasibility of implementing permission control within Wox. Potential for High Reduction if Wox can be modified to manage permissions effectively.

    • Currently Implemented: Not Implemented. Wox likely does not have a built-in permission management system.

    • Missing Implementation: Requires significant development effort to design and implement a permission management system within the Wox core or plugin framework.

Mitigation Strategy: Secure Plugin Update Mechanism (Wox-Focused)

  • Description:

    1. Utilize Wox's Update Mechanism Securely: If Wox provides a plugin update mechanism, ensure it is configured to use HTTPS for downloads.
    2. Enhance Wox Update Verification: If Wox's update mechanism lacks integrity checks (like digital signatures), consider contributing to the Wox project to add signature verification for plugins and updates.
    3. Implement Update Notifications within Wox: Ensure Wox provides clear notifications to users about available plugin updates and allows them to control the update process within the Wox UI.
    4. Fallback Mechanism in Wox Updates: If Wox's update process is prone to errors, implement a robust fallback mechanism within Wox to prevent corrupted updates and ensure stability.

    • Threats Mitigated:

      • Man-in-the-Middle Attacks during Plugin Updates (High Severity): Prevents attackers from intercepting and modifying plugin updates downloaded through Wox's mechanism.
      • Tampered Plugin Updates (High Severity): Ensures that plugin updates processed by Wox are authentic and haven't been tampered with.
      • Installation of Malicious Updates (High Severity): Prevents the installation of fake or malicious plugin updates if Wox implements verification.

    • Impact: High Reduction for all listed threats if Wox's update mechanism is secured and enhanced.

    • Currently Implemented: Partially Implemented. HTTPS for downloads might be used if configured externally, but signature verification and robust update management within Wox are likely missing.

    • Missing Implementation: Requires enhancing Wox's update mechanism with signature verification and improved user control.

Mitigation Strategy: Input Sanitization for Query Bar Input (Wox-Focused)

  • Description:

    1. Implement Input Sanitization in Wox Core: Modify the Wox core codebase to include robust input sanitization and validation for all user input received through the query bar before it is passed to plugins or command execution logic.
    2. Wox Input Validation Rules: Define strict validation rules within Wox for query bar input, considering allowed characters, formats, and potential injection vectors.
    3. Parameterized Commands in Wox Core: Where Wox core directly executes commands based on query bar input, refactor the code to use parameterized commands or prepared statements within Wox to prevent command injection.
    4. Wox Allowlist for Core Commands: If Wox core has built-in commands, implement an allowlist of explicitly allowed commands and arguments within Wox to restrict execution to safe operations.

    • Threats Mitigated:

      • Command Injection via Query Bar (High Severity): Prevents attackers from injecting arbitrary commands into the system through the Wox query bar, by sanitizing input within Wox itself.
      • Path Traversal via Query Bar (Medium Severity): Reduces the risk of attackers using the query bar to access files or directories outside of intended paths by validating paths within Wox.
      • Denial of Service (DoS) via Malformed Input (Low Severity): Prevents malformed or excessively long input processed by Wox from causing crashes or performance issues.

    • Impact: High Reduction for Command Injection, Medium Reduction for Path Traversal, Low Reduction for DoS, all achieved by modifications within Wox.

    • Currently Implemented: Partially Implemented. Some basic input handling might exist in Wox, but comprehensive sanitization and parameterized commands are likely not fully implemented within the Wox core.

    • Missing Implementation: Requires code modifications to the Wox core to implement robust input sanitization, validation, and parameterized command execution.

Mitigation Strategy: Least Privilege Command Execution (Wox-Focused)

  • Description:

    1. Run Wox Process as Standard User: Ensure the Wox application itself is configured to run under a standard user account with minimal privileges. This is a configuration step for Wox deployment.
    2. Restrict Wox Process Capabilities (OS-Level): Utilize operating system level security features (like capabilities, AppArmor, SELinux) to further restrict the privileges of the Wox process. This is a deployment and configuration step for Wox.
    3. Wox Plugin Privilege Separation: If Wox architecture allows, implement a mechanism within Wox to run plugins with even more restricted privileges than the main Wox process.
    4. Avoid SUID/SGID for Wox Binaries: Ensure that the Wox executable and any related binaries are not set with SUID or SGID bits unless absolutely necessary and after rigorous security review. This is a build and deployment consideration for Wox.

    • Threats Mitigated:

      • Privilege Escalation after Compromise (High Severity): Limits the damage an attacker can do if they compromise Wox or a plugin, as the compromised process will have limited privileges due to Wox running with least privilege.
      • System-Wide Impact of Vulnerabilities (High Severity): Reduces the potential for vulnerabilities in Wox or plugins to lead to system-wide compromise because Wox itself is not running with elevated privileges.
      • Lateral Movement after Compromise (Medium Severity): Makes it harder for an attacker to move laterally to other parts of the system after compromising Wox due to limited Wox process privileges.

    • Impact: High Reduction for Privilege Escalation and System-Wide Impact, Medium Reduction for Lateral Movement, all achieved by configuring and deploying Wox with least privilege principles.

    • Currently Implemented: Partially Implemented. Running as standard user is common, but OS-level capability restrictions and plugin privilege separation within Wox are likely missing.

    • Missing Implementation: Requires configuration and deployment steps to run Wox as standard user and restrict process capabilities. Plugin privilege separation would require Wox code modifications.

Mitigation Strategy: Path Sanitization and Restriction (Wox-Focused)

  • Description:

    1. Implement Path Sanitization in Wox Core: Modify the Wox core to include path sanitization and validation for any file paths handled by Wox, especially those derived from user input or plugin requests.
    2. Wox Path Validation Rules: Define strict path validation rules within Wox to prevent path traversal attacks and restrict access to allowed directories.
    3. Directory Allowlisting in Wox: Implement a directory allowlisting mechanism within Wox to explicitly define allowed directories that Wox and plugins can access.
    4. Path Normalization in Wox Core: Ensure Wox core performs path normalization to resolve symbolic links and remove redundant path components, preventing bypasses of path restrictions.

    • Threats Mitigated:

      • Path Traversal Attacks (Medium Severity): Prevents attackers from accessing files or directories outside of their intended scope through Wox's path handling.
      • Unauthorized File Access (Medium Severity): Limits the ability of Wox or plugins to access sensitive files or directories on the system due to Wox-enforced path restrictions.
      • Data Leakage through File Access (Medium Severity): Reduces the risk of sensitive data being leaked through unauthorized file access controlled by Wox's path management.

    • Impact: Medium Reduction for all listed threats, achieved by modifying Wox core to handle paths securely.

    • Currently Implemented: Partially Implemented. Some basic path handling might exist, but comprehensive sanitization, normalization, and directory allowlisting are likely not fully implemented within Wox core.

    • Missing Implementation: Requires code modifications to Wox core to implement robust path sanitization, validation, normalization, and directory allowlisting.

Mitigation Strategy: Regular Wox Updates and Security Patching

    2. Establish Wox Update Process: Define a clear process for testing and applying Wox updates and security patches in a timely manner.
    3. Automate Wox Update Checks (if possible): If Wox provides any built-in update checking mechanism, enable and utilize it to receive notifications about new versions.
    4. Track Wox Version: Maintain a record of the Wox version currently deployed to easily identify when updates are needed.
    5. Prioritize Security Patches: Treat security patches for Wox with high priority and deploy them as quickly as possible after testing.

    • Threats Mitigated:

      • Exploitation of Known Wox Vulnerabilities (High Severity): Prevents attackers from exploiting publicly known vulnerabilities in the Wox application itself that are addressed by updates.
      • Zero-Day Vulnerability Exploitation (Medium Severity): Reduces the window of opportunity for attackers to exploit zero-day vulnerabilities in Wox by ensuring timely patching when updates are released.

    • Impact: High Reduction for Exploitation of Known Vulnerabilities, Medium Reduction for Zero-Day Exploitation, by keeping the Wox application itself updated.

    • Currently Implemented: Partially Implemented. Awareness of updates might exist, but a formal process for monitoring, testing, and applying Wox updates might be missing.

    • Missing Implementation: Requires establishing a formal Wox update management process, including monitoring for updates, testing, and deploying patches promptly.

Mitigation Strategy: Secure Configuration Management (Wox-Focused)

  • Description:

    1. Review Wox Default Configuration: Thoroughly review the default configuration settings of Wox to identify any insecure defaults or settings that could be exploited.
    2. Define Secure Wox Configuration Baseline: Create a secure configuration baseline for Wox, documenting recommended settings and security best practices for Wox configuration.
    3. Configuration Validation for Wox: Implement mechanisms to validate Wox configurations against the secure baseline, either manually or through automated scripts, to detect deviations.
    4. Configuration Management Tools for Wox: Consider using configuration management tools to automate the deployment and enforcement of secure Wox configurations across different environments.
    5. Document Secure Wox Configuration: Provide clear documentation and guidance to users and administrators on how to securely configure Wox and its settings.

      • Misconfiguration Vulnerabilities (Medium Severity): Reduces the risk of vulnerabilities introduced by accidental or intentional misconfigurations of Wox settings.
      • Configuration Drift (Low Severity): Ensures consistent and secure Wox configurations across deployments by preventing configuration drift.

    • Impact: Medium Reduction for Insecure Default Configuration and Misconfiguration Vulnerabilities, Low Reduction for Configuration Drift, all related to Wox configuration.

    • Currently Implemented: Partially Implemented. Default configuration might be reviewed initially, but ongoing validation and automated enforcement of secure Wox configurations are likely missing.

    • Missing Implementation: Requires defining a secure Wox configuration baseline, implementing configuration validation, and potentially adopting configuration management tools for automated enforcement of Wox settings.

Mitigation Strategy: Logging and Monitoring (Wox-Focused)

  • Description:

    1. Enable Wox Logging: Configure Wox to enable comprehensive logging of its activities, including plugin loading, command execution initiated by Wox, errors, and any security-relevant events within Wox itself.
    2. Centralize Wox Logs: Send Wox logs to a centralized logging system for easier analysis, correlation with other application logs, and long-term storage.
    3. Security Monitoring for Wox Logs: Define security monitoring rules and alerts specifically for Wox logs to detect suspicious patterns or potential security incidents related to Wox activity.
    4. Log Retention for Wox: Establish appropriate log retention policies for Wox logs to ensure sufficient historical data is available for security investigations and audits.
    5. Secure Wox Log Storage: Ensure that the storage location for Wox logs is secure and access is restricted to authorized personnel to prevent tampering or unauthorized access to audit trails.

    • Threats Mitigated:

      • Delayed Incident Detection (Medium Severity): Enables faster detection of security incidents related to Wox by providing audit trails and monitoring capabilities of Wox activity.
      • Lack of Visibility into Wox Activity (Low Severity): Improves visibility into Wox usage patterns and potential security issues by logging relevant events within Wox.
      • Insufficient Forensic Information (Medium Severity): Provides valuable forensic information for incident response and investigation in case of security breaches involving Wox.

    • Impact: Medium Reduction for Delayed Incident Detection and Insufficient Forensic Information, Low Reduction for Lack of Visibility, all achieved by logging and monitoring Wox's own activities.

    • Currently Implemented: Partially Implemented. Basic logging within Wox might be enabled, but comprehensive logging, centralized logging, and security monitoring rules specifically for Wox logs are likely missing.

    • Missing Implementation: Requires configuring comprehensive logging within Wox, setting up centralized logging for Wox logs, defining security monitoring rules for Wox logs, and establishing log analysis procedures for Wox activity.
