CVE-2018-10517
In CMS Made Simple (CMSMS) through 2.2.7, the "module import" operation in the admin dashboard contains a remote code execution vulnerability, exploitable by an admin user, because an XML Package can contain base64-encoded PHP code in a data element.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 11.5%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
