Website META Language (WML) 2.0.11 allows local users to overwrite arbitrary files via a symlink attack on (1) the /tmp/pe.tmp.$$ temporary file used by wml_contrib/wmg.cgi and (2) temporary files used by wml_backend/p3_eperl/eperl_sys.c.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
