[ RFP's Note: the Site Server 3.0 SP4 DLLs contain another embedded
password, apES7DAopqLM_1, but it appears that it is only used on a clean
installation (which is then overwritten when the service starts). I did
not mention this in my advisory since it was of no value. Matt makes note
that the password BpES7DAopqLM_1 is embedded in the same DLLs shipped with
the ILS LDAP service. The difference is that it doesn't seem that the ILS
version has been updated to have the password-recreation mechanism. What's
interesting to note are the two hardcoded passwords, when compared:
apES7DAopqLM_1 (Site Server 3.0 SP4 DLLs, LDAP_ANONYMOUS)
BpES7DAopqLM_1 (ILS Server on Win2K, ILS_ANONYMOUS_USER)
Talk about scary. -- rfp ]

It just so happens I *just* had to install the "IIS ILS Site Server"
component on a Win2Ksp2 server *just* before I read your advisory. I
haven't yet checked on the rest of the problems you found, but with just
the IIS ILS Site Server installed, the same problem exists. An
ILS_ANONYMOUS_USER account is created, the password is STILL stored in
%systemroot\system32\inetsrv\dscomobx.dll. This time it's
"BpES7DAopqLM_1".. I can't verify if this is something unique to my
install (like servername rot13'd or something clever) or not, but I can
log in as that local user w/that password. suuuck.
fun! Thanks for the advisory!
