The LG LED Assistant is prone to a remote file disclosure vulnerability with a CVSS score of 7.5. This means remote attackers can access sensitive files on devices running the LG LED Assistant software without any authentication.

The vulnerability exists in the ‘/api/download/updateFile’ endpoint that is used to download software updates. However, there is no validation of the file path provided. This allows attackers to craft requests that disclose any file on the system instead of just software updates.

An attacker could exploit this by simply making HTTP requests with malicious file paths to the vulnerable endpoint on targeted devices. This would let them view configuration files, logs or any other files that the LG LED Assistant process has access to read.

To protect yourself, make sure to update your LG LED Assistant software to the latest version. LG has likely addressed this vulnerability in newer releases. You should also consider changing default credentials if your device uses any. Finally, isolate such IoT devices from directly accessible internet connections if possible for added security.

Staying up-to-date with patches and restricting network access are some effective steps to safeguard yourself from remote file disclosure vulnerabilities like this one in the LG LED Assistant software. Let me know if you have any other questions!
