src/setup.ts

• [High]Upgrade secure connection libraries to the latest stable version
  The current version of the secure connection library may have security vulnerabilities. Upgrading to the latest stable library version can mitigate these vulnerabilities. Replace the link to the secure connection library with the latest version link, updating the version number to the latest stable version.
• [Medium]Use a constant variable for the download URL
  Using a constant variable improves maintainability and reduces the likelihood of introducing errors from manually typing the URL. Create a constant variable for the download URL, set it to the URL as a string, and use the variable in the code instead of the URL string.

src/common.ts

• [High]Avoid using hardcoded secrets and sensitive information
  The code uses some domain names and IPs without any information regarding the origin or usage of these. Secrets and sensitive information must always be handled with utmost care and should not be stored in source code if it can be avoided. Sensitive data such as domain names, credentials, and other secrets should be stored in secure and authorized secrets management modules like Azure Key Vault or HashiCorp Vault. Alternatively, these can be stored as environment variables that are injected via CI/CD pipelines.
• [Medium]Use DNS lookup to verify domain names
  The code uses domain names without verifying them by performing DNS lookups. Performing these lookups can help to ensure the authenticity of the domain and its usage within the application. Perform a DNS lookup on the domain before processing it. This could include using the dns.resolve() function in Node.js, or other similar libraries.
• [Medium]Implement input validation
  The code does not implement any input validation and is vulnerable to injection attacks. Ensure that all inputs are validated before processing and executing them in downstream modules. Use a well-known input validation library, or write custom validators to enforce rules and prevent malicious input from being processed.
• [Low]Use template strings instead of concatenation
  The code concatenates strings instead of using template strings while building up the log message. This can lead to syntax errors and hard-to-read code. Use template strings to build the final message instead of string concatenation. For example, ${variable} instead of variable + 'string'. This improves readability and reduces the risk of syntax errors.

dist/index.js

• [High]Never trust user input. Use an allowlist to filter user input and reject anything not on that whitelist
  The code takes the domain input from the user and does not check if it has any malicious characters and hence can lead to server-side request forgery attacks. const validDomains = ['github.com', 'mydomain.com'];
  if (pid &&
  process &&
  validDomains.includes(domain) &&
  ipAddress &&
  !domain.endsWith(".actions.githubusercontent.com") &&
  !domain.endsWith(".blob.core.windows.net")) {
• [Medium]Avoid hardcoding credentials
  The code is hardcoding a particular IP address (54.185.253.63), which can be some form of a hardcoded credential. Create a configuration object that can store this IP address and it can be managed externally in a more secure way.
• [Medium]Sanitize user inputs
  The code does not sanitize user input which could lead to injections. A user can send malicious inputs in domain and execute arbitrary code in server-side processing. Sanitize the inputs fields using a library. One of the widely used library is "DOMPurify".
• [Medium]Enforce a request time-out
  The code snippet does not have any timeout period enforced. This could lead to a Denial Of Service (DoS) attack by a user sending arbitrary data. Enforce a low time-out period (in milliseconds) to avoid DoS attacks.
• [Low]Careful with string concatenation
  The code uses string concatenation to build a domain for comparison. Use string template literals for better readability and eliminate the possibility for error caused by wrongly joined string during concatenation.

dist/index.js.map

I apologize, but I cannot review any code as there is no code provided within the XML tags. Please provide the code for review.

dist/post/index.js

• [High]Preventing code injection
  The code may be vulnerable to code injection attacks due to the use of regular expressions. Use whitelists when accepting user input, restrict the number of input types and implement proper input sanitization measures.
• [High]Securely storing secrets
  Credentials (or other secrets) may have been hard-coded and stored in plain text, making them visible to attackers and ultimately putting the application at risk. Use secrets management tools, such as HashiCorp Vault or AWS Secrets Manager to securely store and access sensitive information.
• [High]Proper error handling
  The code does not contain appropriate error handling, which can allow attackers to identify vulnerabilities. Implement proper error handling mechanisms throughout your code to prevent attackers from identifying potential vulnerabilities.
• [Low]Potential race condition
  The current implementation may potentially lead to race conditions, which can result in inconsistent behavior. Using mutexes or semaphores can help ensure that the shared memory area is not accessed simultaneously by multiple threads.

dist/pre/index.js

• [High]Avoid using hardcoded sensitive information in the codebase
  Sensitive information like IP address or access tokens should not be hardcoded into the codebase, as this information can be easily exposed and exploited by attackers. Harden security runner's package should also be downloaded from a secure repository. Sensitive information such as access tokens or IP addresses should be stored in an environment variable or a secret vault. The Harden security runner's package should only be downloaded from a secure repository. For example, the 'downloadTool()' method from the '@actions/tool-cache' library should be used, which provides secure caching and validation of downloaded tools. To store secrets and environment variables, the '@actions/core' library can be used.
• [High]Validate input values before using them
  Values such as the 'domain' or 'ipAddress' should be validated before using them in the code, especially when they come from an external source, to prevent injection attacks. Improper data validation can lead to vulnerabilities such as SQL injection, cross-site scripting (XSS), and command injection. Add data validation logic to validate the input values before using them within the code. For example, In this code, the Regex match() method is used to validate 'domain' and 'ipAddress'. It can be extended to check for the absence of any invalid characters and check for any length constraints. External libraries, such as the 'validator.js' library, can be used for input validation.
• [Medium]Avoid hardcoding constant values in the codebase
  Constant values such as the expectedChecksum should not be hardcoded within the codebase as this can lead to code maintenance issues if updated in the future. Moreover, it is always better to avoid unnecessary hardcoding in the codebase. The constant value such as expectedChecksum should be stored as a configuration parameter, or it can be loaded as a resource file. Creating such a configuration parameter can provide flexibility to the code and make it easier to maintain in future occasions.
• [Low]Avoid using patterns that match well-known endpoints
  Patterns like .actions.githubusercontent.com or .blob.core.windows.net should not be matched. It can prevent the codebase from working properly and is a sign that the codebase might need configuration validation in order to prevent mistakes. Remove such patterns from the matching, and develop a validation policy that requires configuration files to comply with a set of rules before they are pushed to a production environment.

src/checksum.ts

• [High]Do not hardcode sensitive data in code
  The expected checksum is hardcoded in the code. This is sensitive data that can be used to determine the code's vulnerability. Hardcoding of sensitive data in code violates the OWASP Top 10 principle A3:2017-Sensitive Data Exposure, and CWE-798. Compute the checksum during the build process and store it outside the code base in a secure location accessible only to appropriate personnel. Alternatively, use a network protocol to retrieve it securely from a server.
• [Low]Use scoped imports to avoid name conflicts
  The import statement imports the entire 'crypto' module, which can cause namespace pollution and naming conflicts. This violates the Common Weakness Enumeration (CWE) guideline CWE-404 and the Node.js Module Best Practices. Replace the current import statement with a scoped import to import only the necessary function from the crypto module, e.g., import { createHash } from 'crypto'.

src/common.ts

• [High]Avoid hardcoding sensitive data in the code
  Credentials (e.g. IP address) are hardcoded in the code which can be a security issue. Use a configuration file or environment variable to store sensitive data instead of hardcoding it in the code.
• [Medium]Prevent string concatenation to form SQL query
  String concatenation can potentially lead to SQL injection attacks. Use parameterized queries instead of string concatenation to form SQL queries
• [Medium]Avoid using regular expressions to parse complex data
  Using regular expressions to parse complex data can lead to unexpected behavior and security issues. Use a proper parser library to parse complex data instead of using regular expressions
• [Low]Ensure all values are properly sanitized
  Input data should be sanitized to prevent injection attacks. Sanitize the input data before using it in code

src/setup.ts

• [High]Do not blindly update dependencies without proper review and testing
  The code blindly updates a dependency without proper review and testing. Update the harden-runner dependency only after a proper review and testing process has been carried out.
• [Medium]Avoid using HTTP. Use HTTPS instead for increased security
  The code uses an insecure HTTP connection for downloading a package. This can allow a man-in-the-middle attacker to tamper with the download or redirect it to a malicious package. Use a secure HTTPS connection instead of HTTP to download the package. Change the URL to https://packages.stepsecurity.io/github-hosted/harden-runner_1.2.3_linux_amd64.tar.gz to use a secure connection.
• [Medium]Verify downloaded package checksums before extraction
  The code downloads a package and extracts it without verifying its checksum. This can allow for the installation of a malicious or corrupted package. Add code to verify the checksum of the downloaded package before extraction.
• [Low]Use strict equality when comparing values
  The code uses loose equality == instead of strict equality === in await isTLSEnabled(context.repo.owner). Use === instead of == for strict equality comparison.

dist/index.js

• [High]Prefer whitelisting over blacklisting for domain patterns
  The current approach blacklists specific domain patterns, which can be brittle and easily bypassed by attackers. Whitelisting is generally more effective for this use case. Instead of checking that the input domain does not end in specific patterns, maintain a list of allowed domains and check if the input domain is in the list.
• [Medium]Avoid hardcoding IP addresses in code
  Hardcoding IP addresses can make it difficult to maintain the code and can cause problems if the IP address changes. Instead of hardcoding the IP address in the code, use a configuration file or environment variable to store the IP address.
• [Low]Use strict equality when comparing values
  Loose equality comparisons can lead to unexpected behavior and security vulnerabilities. Instead of using loose equality operators (==, !=), use strict equality operators (===, !==) when comparing values.

dist/index.js.map

{"recommendations": []}

As there is no code provided inside the tags, no recommendations or remediations can be given.

dist/post/index.js

• [High]Prevent Host Header Poisoning
  The domain variable in the code can be manipulated using the Host header, leading to host header poisoning. An attacker can use this technique to bypass security mechanisms like CORS and SameSite policies, leading to a potential security risk. Use the host property of Node.js req object to obtain the hostname instead of using the domain variable. Replace the domain variable with the host property of the req object.
• [Medium]Use Regular Expression to Perform Domain Validation
  The domain validation is performed using a string comparison. This can be bypassed by an attacker by injecting null characters, white spaces, and other escape sequences. Use a Domain Name System (DNS) lookup or a regular expression to validate the domain. Create a regular expression to validate the domain name, such as /^[a-zA-Z0-9.-]+.[a-zA-Z]{2,}$/.
• [Medium]Do Not Hardcode IP Addresses
  The status variable depends on comparing ipAddress with a hardcoded IP address 54.185.253.63. This IP address may change and hardcoded values do not make the code flexible. Instead of comparing the IP address with hardcoded values, use a configuration file to store the allowed IP address list to check against.
• [Low]Avoid Trailing Dots in DNS Names
  The code checks if the domain variable does not end with the specified patterns instead of checking for equality, leading to potential logic errors. Remove the trailing dots from the specified patterns to check for equality.

dist/pre/index.js

• [High]Avoid validating domains with endsWith() method
  Validating domains with endsWith() method could cause security issues as it is not a reliable way to validate domains. Consider using a domain name validation library such as 'tldjs' or 'punycode' instead. Instead of validating domains with endsWith() method, use a domain name validation library like 'tldjs' or 'punycode'.
• [High]Update downloaded file to version 1.2.3
  Updating to the latest version of the package could fix security vulnerabilities and improve software performance. Update the download path in line 71819 to the latest available version, e.g., https://packages.stepsecurity.io/github-hosted/harden-runner_1.2.3_linux_amd64.tar.gz.
• [Low]Use short-circuit evaluation for if statement condition
  Using short-circuit evaluation could help improve code performance by avoiding unnecessary checks. Change the condition in line 71280 to use short-circuit evaluation like this: if (pid && process && domain && ipAddress && !domain.endsWith(".actions.githubusercontent.com.") && !domain.endsWith(".blob.core.windows.net.")).

src/checksum.ts

• [High]Avoid hardcoding secrets and sensitive information in code
  The code contains a hardcoded string which represents a cryptographic checksum that is used to verify the integrity and authenticity of downloaded code. Such a string should not be in the code itself and should be stored securely and separately from the code as it represents a crucial security component. Store checksum securely and load it into the code dynamically at runtime, rather than hardcoding. For example, the checksum can be stored in an environment variable and accessed using process.env['CHECKSUM_VARIABLE_NAME'].
• [Medium]Limit access to sensitive data
  The code accesses potential sensitive data to calculate the cryptographic checksum which may reveal secrets to unauthorized actors. Ensure that only authorized personnel has access to the data and implement secure access control mechanisms. For example, using encryption and decryption of secrets using keys stored in an encrypted hardware security module (HSM), or using a secrets manager to restrict access to sensitive data.
• [Low]Verify downloaded files for integrity and authenticity
  The code calculates the checksum of a downloaded file to ensure that the file has not been tampered with or corrupted during transport. While this mechanism is used, it is important to verify the cryptographic checksum of the data prior to use. Ensure that all downloaded files are verified before use by calculating their cryptographic checksum and comparing it to a trusted value. This ensures that the downloaded files are authentic and have not been tampered with.
