In Earcms Ear Music through 4.1 build 20170710, remote authenticated users can execute arbitrary PHP code by changing the allowable music-upload extensions to include .php in addition to .mp3 and .m4a in admin.php?iframe=config_upload, and then using user.php/music/add/ to upload the code.

An issue found in Earcms Ear App v.20181124 allows a remote attacker to execute arbitrary code via the uload/index-uplog.php.
