Fix for path traversal vulenerability

ParisNeo commented 4 months ago

Hi, I have spotted a path traversal vulenerability in the XTTS server that allows an attacker to access any file on the host. I have added the following to the endpoint to forbid the recovery of files outside the served folder.

    # A fix for path traversal vulenerability. 
    # An attacker may summon this endpoint with ../../etc/passwd and recover the password file of your PC (in linux) or access any other file on the PC
    if ".." in file_name:
        raise HTTPException(status_code=404, detail=".. in the file name! Are you kidding me?")

Summary by CodeRabbit

Security Improvements
- Enhanced security for the get_sample endpoint to prevent path traversal attacks.

Walkthrough

A crucial update has been made to enhance the security of the xtts_api_server by fortifying the get_sample endpoint. This measure effectively blocks path traversal attacks by rejecting any file name requests that include the potentially malicious ".." sequence, ensuring users cannot access unauthorized files.

Changes

File Path	Change Summary
`.../server.py`	Added a security check to prevent path traversal in the `get_sample` endpoint.

🐇✨
In the code's burrow, deep and vast,
A tiny change was made, not fast.
To keep the danger far at bay,
".." in paths, we say "nay".
Safe and sound beneath the moon,
Our server hums a safer tune.

Tips

### Chat There are 3 ways to chat with CodeRabbit: - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit-tests for this file.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit tests for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository from git and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit tests.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger a review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - The JSON schema for the configuration file is available [here](https://coderabbit.ai/integrations/coderabbit-overrides.v2.json). - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json` ### CodeRabbit Discord Community Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback.
