Quiz and Survey Master <= 7.0.1 - Arbitrary File Upload

Unrestricted Upload of File with Dangerous Type
CVE Not available
CVSS Critical (9.8)

Researcher Jerome Bruandet
Description

The Quiz and Survey Master plugin for WordPress is vulnerable to arbitrary file uploads due to missing filename sanitization in the qsm_upload_image_fd_question() function in versions up to, and including, 7.0.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server using a double extension attack method which may make remote code execution possible on sites with a configuration that parse the first extension of a file. This is due to an incomplete fix of CVE-2020-35949.
