Hi
I noticed index server sample file is vulnerable which reveals file info and
physical path.
Vulnerable
Microsoft Index Server 2.0
+ IIS 4.0 + Windows NT Server 4.0
+ Service Pack 6a
Details
The Index Server Sample file SQLQHit.asp shipped with Microsoft Index
Server 2.0 and Option pack 4.0 , is installed under the directory
"/inetpub/iissamples/ISSamples/" by default. SQLQHit.asp file is used for
SQL based Search, can be used by a malicious user to gather information
about files in virtual folders under certain conditions.
By sending certain type of query to SQLQHit.asp page, malicious user can
exploit this vulnerability. This vulnerability reveals the physical path,
file attribute and some lines source code of files in virtual directory.
Malicious user can't modify or write through this vulnerability. But he/she
can gather more information about the files in virtual directory. By default
/inetpub/iissamples/ISSamples/ folder is installed while installing Index
server & IIS. The vulnerability can be exploited only if index server runs.
This vulnerability can be exploited both remotely as well as locally.
Exploit
http://local-iis-server/iissamples/ISSamples/SQLQHit.asp?CiColumns=*&CiScope
=webinfo
reveals the corresponding physical path of the files in virtual folder. It
also reveals file attribute, some lines code of the file. If sensitive
information like passwords kept inside asp,asa file, it may revealed through
characterization field.
The vulnerability can be exploited through the following queries also
http://local-iis-server/iissamples/ISSamples/SQLQHit.asp?CiColumns=*&CiScope
=extended_fileinfo
http://local-iis-server/iissamples/ISSamples/SQLQHit.asp?CiColumns=*&CiScope
=extended_webinfo
http://local-iis-server/iissamples/ISSamples/SQLQHit.asp?CiColumns=*&CiScope
=fileinfo
Note: This vulnerability can be exploited only when /iissamples/ISSamples
folder exists and Index server running. ( By default /iisamples/ISSamples/
folder installed and index server runs)
Impact of the vulnerability
Vulnerability reveals the physical path of the file in virtual folders.
Malicious user can gather information about the files like created date ,
file attribute and even some lines code of the file.
Solution
Never install sample files on production servers. If you have sample folders
like iissamples/issamples/ , remove sample files. Microsoft promises next
version of Index service won't have this vulnerablity.
