Attack Vector Name: Data Source Credential Theft

  • Description: Attackers aim to steal credentials used by Redash to connect to data sources (databases, APIs, etc.). This allows them to directly access and potentially exfiltrate data from these sources, bypassing Redash's intended access controls.
  • Potential Impact:
    • Direct access to sensitive data in connected data sources.
    • Data breaches and exfiltration.
    • Potential for further attacks on data sources if credentials allow write access.
  • Recommended Mitigations:
    • Secure Credential Storage: Use robust encryption for storing data source credentials within Redash. Consider using dedicated secrets management systems (like HashiCorp Vault, AWS Secrets Manager, etc.) instead of storing credentials directly in Redash configuration files or environment variables.
    • Principle of Least Privilege: Grant Redash data source connection users only the minimum necessary permissions on the data sources.
    • Regular Security Audits: Audit Redash configurations and credential storage mechanisms regularly.
    • Access Control: Restrict access to Redash configuration files and environment variables to only authorized personnel and systems.

Attack Vector Name: Exploit Weak Credential Storage

  • Description: Attackers target weaknesses in how Redash stores data source credentials. This could involve exploiting weak encryption algorithms, insecure storage locations (e.g., plain text configuration files), or vulnerabilities in Redash's code that expose credentials.
  • Potential Impact:
    • Compromise of data source credentials.
    • Leads directly to Data Source Credential Theft and its impacts.
  • Recommended Mitigations:
    • Strong Encryption: Use strong, industry-standard encryption algorithms to protect stored credentials.
    • Secure Storage Locations: Store configuration files and sensitive data in secure locations with restricted access permissions. Avoid storing credentials in easily accessible locations like web-accessible directories.
    • Code Reviews: Conduct regular code reviews to identify and fix potential credential leakage vulnerabilities in Redash's codebase.
    • Penetration Testing: Include credential storage security in penetration testing scopes.

Attack Vector Name: Access Redash Configuration Files

  • Description: Attackers attempt to gain unauthorized access to Redash's configuration files (e.g., redash.conf, environment variables, settings databases). These files often contain sensitive information, including data source credentials, API keys, and internal configuration details.
  • Potential Impact:
    • Exposure of data source credentials.
    • Exposure of API keys and other sensitive configuration data.
    • Information disclosure that can aid in further attacks.
  • Recommended Mitigations:
    • Secure File Permissions: Implement strict file system permissions on Redash configuration files, ensuring only the Redash application user and authorized administrators have read access.
    • Environment Variable Security: If using environment variables, ensure the environment where Redash runs is securely configured and access to environment variables is restricted.
    • Principle of Least Privilege: Limit access to the Redash server and its file system to only necessary personnel and processes.
    • Regular Security Audits: Audit file permissions and access controls regularly.

Attack Vector Name: Query Injection Vulnerabilities

  • Description: Attackers exploit vulnerabilities in Redash's query execution engine that allow them to inject malicious code into queries sent to data sources. This is most commonly SQL Injection, but can also apply to NoSQL databases or APIs if Redash doesn't properly sanitize user input used in queries.
  • Potential Impact:
    • Data Breach: Exfiltration of sensitive data from data sources.
    • Data Modification: Modification or deletion of data in data sources.
    • System Compromise: In some cases (especially with SQL Injection), attackers can achieve command execution on the database server or even the Redash server itself.
  • Recommended Mitigations:
    • Parameterized Queries: Always use parameterized queries or prepared statements when constructing queries in Redash, especially when incorporating user-provided input. This prevents user input from being interpreted as code.
    • Input Sanitization: Sanitize user input used in query parameters, even with parameterized queries, to prevent unexpected behavior or bypasses.
    • Principle of Least Privilege (Database Users): Use database users for Redash connections that have minimal necessary privileges. Avoid using highly privileged database accounts.
    • Web Application Firewall (WAF): Consider using a WAF to detect and block common query injection attempts.
    • Regular Security Testing: Conduct regular penetration testing and vulnerability scanning specifically targeting query injection vulnerabilities.

Attack Vector Name: Exploit Insufficient Input Sanitization in Query Parameters

  • Description: This is the underlying weakness that enables Query Injection. Redash fails to properly sanitize or validate user-provided input before incorporating it into database queries. This allows attackers to craft malicious input that is then executed as part of the query.
  • Potential Impact:
    • Leads directly to Query Injection Vulnerabilities and their impacts.
  • Recommended Mitigations:
    • Input Validation: Implement robust input validation on all user-provided input that is used in queries. Validate data type, format, and length.
    • Output Encoding (Context-Aware): While primarily for XSS, context-aware output encoding can also help in some cases to prevent injection by ensuring user input is treated as data, not code, in the query context.
    • Code Reviews: Focus code reviews on areas where user input is processed and incorporated into queries.

Attack Vector Name: SQL Injection

  • Description: A specific type of Query Injection targeting SQL databases. Attackers inject malicious SQL code into queries, exploiting insufficient input sanitization to manipulate the database.
  • Potential Impact:
    • Data Breach: Exfiltration of data from SQL databases.
    • Data Modification/Deletion: Altering or deleting data in SQL databases.
    • Privilege Escalation: Potentially gaining higher privileges within the database.
    • Command Execution (in some cases): In some database systems (like SQL Server with xp_cmdshell), SQL Injection can lead to OS command execution on the database server.
  • Recommended Mitigations:
    • Parameterized Queries (Crucial): This is the primary defense against SQL Injection.
    • Input Sanitization (Defense in Depth): While parameterized queries are key, input sanitization adds an extra layer of defense.
    • Principle of Least Privilege (Database Users): Use database users with minimal privileges for Redash connections.
    • Database Security Hardening: Harden the underlying SQL database server itself according to security best practices.
    • WAF (Web Application Firewall): A WAF can help detect and block SQL Injection attempts.

  • Description: This is the direct consequence of successful SQL Injection. Attackers leverage the injection vulnerability to execute arbitrary SQL queries of their choosing.
  • Potential Impact:
    • Critical Data Breach: Mass exfiltration of highly sensitive data.
    • Complete Data Loss/Corruption: Deletion or corruption of critical data.
    • Full System Compromise: If command execution is possible, attackers can gain complete control of the database server and potentially pivot to other systems.
  • Recommended Mitigations:
    • Prevent SQL Injection (Primary Focus): All mitigations for SQL Injection directly prevent this attack step.
    • Database Activity Monitoring: Implement database activity monitoring to detect and alert on suspicious or malicious SQL queries being executed.
    • Incident Response Plan: Have a well-defined incident response plan in place to handle potential SQL Injection attacks and data breaches.

Attack Vector Name: Cross-Site Scripting (XSS)

  • Description: Attackers inject malicious JavaScript code into the Redash UI. When other users view the affected parts of the UI (e.g., dashboards, queries, visualizations), the malicious script executes in their browsers.
  • Potential Impact:
    • Account Compromise: Session hijacking, cookie theft, credential theft, allowing attackers to impersonate legitimate users.
    • Data Theft (Client-Side): Accessing data visible to the user within the Redash UI.
    • Malware Distribution: Redirecting users to malicious websites or serving malware.
    • Defacement: Altering the appearance of the Redash UI for other users.
  • Recommended Mitigations:
    • Output Encoding/Escaping (Crucial): Implement robust output encoding/escaping for all user-provided content rendered in the Redash UI. Use context-aware escaping appropriate for HTML, JavaScript, and URLs.
    • Content Security Policy (CSP): Implement a strong CSP to mitigate XSS risks by controlling the resources the browser is allowed to load and execute.
    • Input Validation (Defense in Depth): While output encoding is primary, input validation can help prevent some XSS by rejecting or sanitizing malicious input before it's stored.
    • Regular Security Testing: Conduct regular security testing, including XSS vulnerability scanning and manual testing.

Attack Vector Name: Inject Malicious JavaScript into Redash UI

  • Description: Attackers find ways to inject malicious JavaScript code into Redash. This can be through various means, including:
    • Stored XSS: Injecting scripts into persistent data like dashboard names, query descriptions, visualization titles.
    • Reflected XSS: Injecting scripts into URL parameters or error messages that are then reflected back in the page.
  • Potential Impact:
    • Leads directly to Cross-Site Scripting (XSS) and its impacts.
  • Recommended Mitigations:
    • Focus on Output Encoding/Escaping: This is the most effective mitigation for preventing JavaScript injection from becoming executable XSS.
    • Input Validation (Defense in Depth): Validate and sanitize user input to reduce the likelihood of malicious script injection in the first place.

Attack Vector Name: Stored XSS

  • Description: Attackers inject malicious JavaScript that is persistently stored within Redash's database. This could be in dashboard names, query descriptions, visualization titles, or other user-editable fields. When other users view these stored items, the malicious script executes.
  • Potential Impact:
    • Persistent XSS attacks affecting all users who view the compromised content.
    • Higher impact than reflected XSS as it doesn't require social engineering to trigger for each user.
  • Recommended Mitigations:
    • Robust Output Encoding/Escaping (Crucial for Stored XSS): Ensure all stored user-provided content is properly encoded/escaped when rendered in the UI.
    • Input Validation and Sanitization: Sanitize and validate user input before storing it in the database to prevent malicious script injection.
    • Regular Content Audits: Periodically audit stored content for suspicious or malicious scripts.

Attack Vector Name: Execute Malicious Scripts on Other Users' Browsers

  • Description: This is the direct consequence of successful XSS. The injected JavaScript code executes in the browsers of other Redash users, allowing the attacker to perform various malicious actions on their behalf.
  • Potential Impact:
    • Account Takeover: Session hijacking allows attackers to fully control user accounts.
    • Credential Theft: Stealing user credentials for Redash or other systems.
    • Data Theft (Client-Side): Accessing and exfiltrating data visible to the user in the Redash UI.
    • Further Attacks: Using compromised accounts to launch further attacks within Redash or against connected systems.
  • Recommended Mitigations:
    • Prevent XSS (Primary Focus): All mitigations for XSS directly prevent this attack step.
    • Session Management Security: Implement robust session management practices (e.g., HTTP-only cookies, secure flags, session timeouts) to minimize the impact of session hijacking.
    • Multi-Factor Authentication (MFA): MFA can help mitigate the impact of credential theft by adding an extra layer of security.

Attack Vector Name: Vulnerable Dependencies

  • Description: Redash, like most applications, relies on third-party libraries and frameworks. These dependencies may contain known security vulnerabilities. Attackers can exploit these vulnerabilities to compromise Redash.

  • Description: Redash, or its underlying components (like databases), might come with default usernames and passwords. If these are not changed during deployment, attackers can easily use them to gain unauthorized access.
  • Potential Impact:
    • Critical System Compromise: Default admin credentials can grant full administrative access to Redash and potentially the underlying server.
    • Data Breach: Full access to data managed by Redash.
  • Recommended Mitigations:
    • Change Default Credentials Immediately (Critical): The first and most crucial step is to change all default usernames and passwords for Redash, its database, and any related services during initial deployment.
