DESCRIPTION:
Gustavo Sorondo has discovered some vulnerabilities in PhreeBooks,
which can be exploited by malicious users to conduct script insertion
attacks and disclose sensitive information.

1) Input passed via the "cm_primary_name" parameter to index.php
while adding a new customer, the "vm_primary_name" parameter to
index.php while adding a new vendor, and the "em_primary_name"
parameter to index.php while adding a new employee is not properly
sanitised before being displayed to the user. This can be exploited
to insert arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the
malicious data is being viewed.

Successful exploitation requires "Add" privileges for "Maintain
Customers", "Maintain Vendors", or "Maintain Employees".

2) Input passed via the "description_short" parameter to index.php
while adding or editing an inventory item is not properly sanitised
before being displayed to the user. This can be exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site when the malicious
data is being viewed.

Successful exploitation requires "Full" privileges for
"Edit/Maintain" in "Inventory".

3) Input passed via the "cat" and the "language" parameters to
index.php is not properly verified before being used to include
files. This can be exploited to include arbitrary files from local
resources via directory traversal sequences and URL-encoded NULL
bytes.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 2.0. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised and
verified.
