4) Description of Vulnerability

Secunia Research has discovered six vulnerabilities in PhreeBooks, 
which can be exploited by malicious users to disclose sensitive 
information.

1) Input passed via the "db" parameter to soap/application_top.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 requires that "magic_quotes_gpc" is disabled.

2) Input passed via the "module" parameter to index.php (when "cat" is
set) 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 requires that "magic_quotes_gpc" is disabled.

3) Input passed via the "op" parameter to index.php (when "cat" is set
and "module" is set to "ajax") 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 requires that "magic_quotes_gpc" is disabled.

4) Input passed via the "subject" parameter to index.php (when "cat" 
is set to "setup" and "module" is set to "popup_setup") 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 requires that "magic_quotes_gpc" is disabled.

5) Input passed via the "subject" parameter to index.php (when "cat" 
is set to "services" and "module" is set to "popup_tracking") 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 requires that "magic_quotes_gpc" is disabled.

6) Input passed via the "subject" parameter to index.php (when "cat" 
is set to "services" and "module" is set to "popup_label_mgr") 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 requires "Read Only" permissions for "Shipping
Manager" in the "Tools" section and that "magic_quotes_gpc" is 
disabled.
