Description
HFS2 version 2.4.0 and earlier contains an unauthenticated arbitrary file access vulnerability that allows unauthenticated attackers to read, write, append, and delete files anywhere the HFS service account has filesystem access outside the shared folder. Attackers can exploit the macro dispatcher's lack of authorization model combined with the path resolver's failure to confine absolute paths to manipulate the template engine and compromise the confidentiality, integrity, and availability of the host.
