How to Fix CVE-2024-2029

To remediate this vulnerability, upgrade all affected Github.com/go skynet/LocalAI dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/go-skynet/LocalAI fixed: 2.10.0 
Upgrade github.com/go-skynet/LocalAI to 2.10.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/go-skynet/LocalAI

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-2029, inspect your project dependencies for Github.com/go skynet/LocalAI:

inspect dependencies for github.com/go-skynet/LocalAI

Analyze the terminal output to locate any version of Github.com/go skynet/LocalAI in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.10.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Github.com/go skynet/LocalAI, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A command injection vulnerability exists in the `TranscriptEndpoint` of mudler/localai, specifically within the `audioToWav` function used for converting audio files to WAV format for transcription. The vulnerability arises due to the lack of sanitization of user-supplied filenames before passing them to ffmpeg via a shell command, allowing an attacker to execute arbitrary commands on the host system. Successful exploitation could lead to unauthorized access, data breaches, or other detrimental impacts, depending on the privileges of the process executing the code.
