CVE-2018-7486 Information

Description

Blue River Mura CMS before v7.0.7029 supports inline function calls with an [m] tag and [/m] end tag without proper restrictions on file types or pathnames which allows remote attackers to execute arbitrary code via an [m]$.dspinclude(../pathname/executable.jpeg)[/m] approach where executable.jpeg contains ColdFusion Markup Language code. This can be exploited in conjunction with a CKFinder feature that allows file upload.
