CVE-2020-35949
It made it possible for unauthenticated attackers to upload arbitrary files and achieve remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in the Quiz and Survey Master plugin before 7.0.1 for WordPress. It made it possible for unauthenticated attackers to upload arbitrary files and achieve remote code execution. If a quiz question could be answered by uploading a file, only the Content-Type header was checked during the upload, and thus the attacker could use text/plain for a .php file.
