Unauthenticated Local File Inclusion in AutoParts

Detection Guidance

The vulnerability is a Local File Inclusion (LFI) flaw in the WordPress AutoParts Theme versions 1.5.8 and below, which allows unauthenticated attackers to include local files on the target website.

To detect this vulnerability on your system, you can look for suspicious HTTP requests attempting to include local files via URL parameters or paths related to the AutoParts theme.

Common detection methods include monitoring web server logs for requests containing typical LFI payloads such as "../../" sequences or attempts to access sensitive files like "/etc/passwd".

Example commands to search for potential exploitation attempts in web server logs (assuming Apache logs):

• grep -iE "(\.\./|etc/passwd|boot.ini|windows/win.ini)" /var/log/apache2/access.log
• grep -i "autoparts" /var/log/apache2/access.log

Additionally, you can use web vulnerability scanners or tools that specifically test for LFI vulnerabilities by sending crafted requests to the target URL parameters.

Since there is no official patch yet, applying temporary mitigation rules from Patchstack or consulting with your hosting provider or web developer is recommended.
