K-AShare xkas /var/adm/appletalk/icons directory symlink

kashare-xkas-icon-symlink (8002) The risk level is classified as MediumMedium Risk


XInet K-AShare could allow a local attacker to launch a symlink attack, caused by insecure permissions on the /var/adm/appletalk/icons directory. A local attacker could replace the VOLICON file in this directory and create a symbolic link to an arbitrary file on the system, which would cause the symbolically linked file to be copied to the /var/adm/appletalk/icons directory with the file name of .HSicon once the xkas program is executed. An attacker could use this vulnerability to read arbitrary files on the system because the /var/adm/appletalk/icons directory is world-readable.
