wmtv insecure configuration file symlink

wmtv-config-file-symlink (8110) The risk level is classified as MediumMedium Risk


wmtv could allow a local attacker to launch a symlink attack. wmtv is installed setuid root, which causes the wmtv configuration file to be written back as the superuser. A local attacker could exploit this vulnerability by creating symbolic links from the configuration file to arbitrary files on the system, which would be overwritten once wmtv is executed.
