GHSA-364W-9G92-3GRQ

Vulnerability from github – Published: 2021-11-16 23:40 – Updated: 2021-11-17 22:04

Withdrawn 2021-11-17

Summary

Withdrawn: Laravel Framework does not sufficiently block the upload of executable PHP content.

Details

Withdrawn

This advisory has been withdrawn after the maintainers of Laravel noted this issue is not a security vulnerability with Laravel itself, but rather a userland issue.

Original CVE based description

Laravel Framework through 8.70.2 does not sufficiently block the upload of executable PHP content because Illuminate/Validation/Concerns/ValidatesAttributes.php lacks a check for .phar files, which are handled as application/x-httpd-php on systems based on Debian. In some use cases, this may be related to file-type validation for image upload (e.g., differences between getClientOriginalExtension and other approaches).
