Subject: Alert: IIS 4.0 metabase can reveal plaintext passwords1 E- h* I7 C b
Hi all, ( b) c% {6 x! D& L, LWe knew that Windows NT passwords are stored in 7 different places across' n" I* N& {& c
the system. Here is a 8th place: the IIS 4.0 metabase.( z; i5 [, O% A. h: o Q9 p
IIS 4.0 uses its own configuration database, named "metabase", which can 2 n, _% t& O8 b: B c" B. Dbe compared to the Windows Registry: the metabase is organised in Hives,3 V: e3 _- M1 W& {# Q; K2 Q( d
Keys and Values. It is stored in the following file:* _+ C, f( h2 T# I
C:\WINNT\system32\inetsrv\MetaBase.bin 5 p$ `# V; @2 NThe IIS 4.0 metabase contains these passwords:1 \/ n* Z5 D/ T7 r

- UNC username and password used to connect to another server if one of: t' E- A+ }$ I2 V7 V5 q- l

Note that the usernames are in unicode, clear text, that the passwords are : \( x7 o6 {" Z: E4 J- Gsrambled in the metabase.ini file, and that only Administrators and SYSTEM " t t1 Y+ P$ F0 V v2 e- whave permissions on this file.5 P5 A4 e7 f6 E8 U" Z" c
BUT a few lines of script in a WSH script or in an ASP page allow to print ' S v# M.

Obviously this represents a significant risk for Web servers that allow& C/ I# j& ~5 l& T" y9 m
logons and/or remote access, although I did not see any exploit of the 2 Y* o% D- \: }7 d1 K3 k3 c8 Uproblem I am reporting yet. Here is an example of what can be gathered: 8 I; |& z4 \6 M! l7 K: m K" 4 C* r w8 Y" G! |IIS 4.0 Metabase: u* d/ H$ w& [% ^4 S

an IIS 4.0 Web Site Operator. Then, he launches a WSH script that extracts6 Y$ {3 V' Z: |
