On July 17, 2020, our Threat Intelligence group discovered two vulnerabilities within Quiz plus Survey Master (QSM), a WordPress wordpress plugin installed on over 30, 500 sites. These flaws managed to get possible for unauthenticated attackers in order to upload arbitrary files in addition to achieve remote code performance, as well as delete arbitrary documents like a site’s wp-config. php file which could effectively have a site offline and allow a good attacker to take over the susceptible site.

All of us initially reached out to the plugin’s team on July seventeen, 2020 through their assistance forum and followed up once again on July 21, 2020. After another week associated with no response, we provided to ExpressTech, the plugin’s parent company, on This summer 28, 2020, via the contact page on their site providing a great end-of-week deadline for reaction prior to escalating our disclosure. They responded on Aug 1, 2020 confirming the right disclosure inbox, and we delivered the full disclosure details more than on Monday, August a few, 2020. A patch was launched just a few days later on September 5, 2020.

We highly recommend updating to be able to version 7. 0. one immediately to keep your site guarded against any attacks trying to exploit this vulnerability.

Wordfence Premium customers, and sites still utilizing the free version of Wordfence, have been protected against the majority of exploits targeting these weaknesses due to the Wordfence firewall’s built/in rules protecting against malicious document uploads, local file addition, and directory traversal.

While testing the particular patch released by the QSM team on August five, 2020, we discovered our own firewall did not provide sufficient protection against this vulnerability in case of a Cross-Site Request Forgery (CSRF) exploit attempt focusing on administrators. Though it is more unlikely that these vulnerabilities would be used this way, we quickly a new rule to provide optimal safety. Premium users received the brand new firewall rule on July 5, 2020. Sites nevertheless using the free Wordfence wordpress tool will receive this rule upon September 5, 2020.

Questions and Survey Master is definitely an easy to use plugin designed to include quizzes and surveys to some WordPress site. One function allows site owners to apply file uploads as a reply type for a quiz or even survey, which could be within a number of scenarios, such as a resume questionnaire with a PDF curriculum vitae upload at the end.

Unfortunately, this feature has been insecurely implemented. The inspections performed prior to allowing folders to upload only examined how the general settings had been configured for the file add question. For example , it examined what file-type was chosen to be “allowed” and the quality permitted, per user specific settings.
