COMMAND
convert.bas
SYSTEMS AFFECTED
Systems running Novell's HTTP server
PROBLEM
A remote user can read any file on the remote file system using
this CGI. This means that if you are running the Novell HTTP
server and have the 'out of box' CGI's, you are breached.
Exploit code:
http://victim.com/scripts/convert.bas?../../anything/you/want/to/view
In a random sampling of 10 sites there was 1 site that restricted
using ../ so (I assume) that by using Novell's security you CAN
restrict this bug. However you can access files like
AUTOEXEC.NCF, and even login scripts in the hidden _NETWARE
directory (if you know the name). It does appear you are
restricted to the SYS: volume, however if you are using XCONSOLE
and have your remote console password in plaintext (instead of
encrypted) you are just inviting someone to telnet to the server
console....
