To address multiple Salesforce-specific security vulnerabilities, follow these comprehensive best practices:
**SOQL/SOSL Injection**:
- Use bind variables or `escapeSingleQuotes` to sanitize user input.
- Avoid directly injecting user input into queries.
- For dynamic SOQL/SOSL, use `sObjectType` or `sObjectFields` to prevent injection and ensure proper CRUD/FLS checks.
**Sharing Violations**:
- Ensure operations are executed in the appropriate sharing context.
- Use "with sharing" or "without sharing" as required by the business logic, and document the reasoning in your submission.
- Clearly define scenarios where guest or automated users require specific access.
**FLS (Field-Level Security) and CRUD Violations**:
- Implement checks using methods like `isAccessible()`, `isUpdateable()`, and `isDeletable()` for DML operations.
- If using USER_MODE, ensure it aligns with your use case and does not break functionality.
- Document any custom permission checks or mitigations in your submission.
- Ensure all instances across the codebase are addressed.
**DML Operations Inside Loops**:
- Refactor the code to perform bulk operations outside the loop to improve code quality and avoid performance issues.
- Security reviewers focus on actual security concerns, so ensure that false positives are documented with appropriate justifications.
**Software Versions**:
- Regularly update all software components to the latest secure versions.
- For software with known vulnerabilities unrelated to your use case, document them as false positives and explain why they are safe for your solution.
- Use the Common Vulnerabilities and Exposures (CVE) database to identify and address vulnerabilities.
**Data Storage**:
- Store sensitive data, such as API keys or client secrets, in protected custom settings, encrypted custom metadata, or using the Crypto API.
- Avoid using public custom settings for sensitive information.
- For external credentials, ensure secure storage and provide configuration options for customers.
- Avoid hardcoding sensitive data in the code and ensure sensitive data is encrypted and not exposed in logs or debug outputs.
**JavaScript in Salesforce DOM**:
- Store JavaScript in static resources instead of directly loading it into the Salesforce DOM.
- Avoid linking JavaScript from third-party servers.
- Use secure methods like `URLFOR()` or `/resource[/timestamp]/YourStaticResourceName` to load static resources.
- If dynamic content is necessary, host it externally and embed it via an iframe in a Visualforce page to ensure it is not associated with a Salesforce domain.
**Session ID Usage**:
- Do not share session IDs outside the Salesforce organization.
- Approved use cases include internal operations like Metadata API calls or SOAP API usage where the session ID does not leave the org.
- For external integrations, use OAuth tokens via a ConnectedApp with appropriate scopes instead of session IDs.
**General Recommendations**:
- Follow secure coding practices and use tools like Checkmarx and Salesforce Code Analyzer to identify and mitigate vulnerabilities.
- For issues like insecure session handling or improper use of JavaScript, ensure compliance with best practices.
- Prepare detailed documentation for any false positives and ensure all vulnerabilities are addressed before submission for security review.
- Engage with the security review team for guidance on unresolved issues.
By implementing these measures, you can effectively address the identified security findings and ensure your application meets Salesforce security standards.
