CVE-2018-20127
An issue was discovered in zzzphp cms 1.5.8. del_file in /admin/save.php allows remote attackers to delete arbitrary files via a mixed-case extension and an extra '.' character, because (for example) "php" is blocked but path=F:/1.phP. succeeds.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
