Webtrends HTTP Server %20 bug

[Auriemma Luigi <kaino3 () genie it>]

*** I'm sorry if this bug is already known, but I have not found it in the
SecurityFocus and other archives.

Author: Auriemma Luigi



VERSION TESTED: Webtrends HTTP Server V3.1c (Webtrends Reporting Server)

RISK: Viewing the source of the cgi scripts


The bug is really simple. If the attacker insert an unicode space (%20)
after the script file, the server think that the file requested is not a
cgi script and for this it shown the source; this is an example:

http://host/remote_login.pl%20


And the result is the source of "remote_login.pl".

I have not contacted Webtrends because I wait for more opinions, and for
result with other versions.



Thanks for your attention.
