CVE-2017-7695
Unrestricted File Upload exists in BigTree CMS before 4.2.17: if an attacker uploads an 'xxx.php[space]' file, they could bypass a safety check and execute any code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.99%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
