4) Description of Vulnerability

Secunia Research has discovered eight vulnerabilities in PhreeBooks,
which can be exploited by malicious people to conduct cross-site
scripting attacks.

1) Input passed via arbitrary parameters to index.php (when "cat",
"module", and "subject" are set) is not properly sanitised in the
"gen_get_all_get_params()" function in modules/general/functions
/gen_functions.php before being returned to the user. This can be 
exploited to execute arbitrary HTML and script code in a user's 
browser session in context of an affected site.

2) Input passed via the "search_text" parameter to index.php (when 
"cat" and "module" are set) is not properly sanitised before being 
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

3) Input passed via the "date_from" and "date_to" parameters to 
index.php (when "cat" is set to "general" and "module" is set to
"search") is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

4) Input passed via the "search_field" parameter to includes/addons
/PhreeHelp/leftframe.php is not properly sanitised before being 
returned to the user. This can be exploited to execute arbitrary HTML 
and script code in a user's browser session in context of an affected 
site.

5) Input passed via the "img" parameter to index.php (when "cat" is 
set to "inventory" and "module" is set to "popup_image") is not 
properly sanitised before being returned to the user. This can be 
exploited to execute arbitrary HTML and script code in a user's 
browser session in context of an affected site.

6) Input passed to the "form" parameter in modules/services/pages
/popup_shipping/js_include.php is not properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML 
and script code in a user's browser session in context of an affected 
site.

7) Input passed via the "index" parameter to index.php (when "cat" is
set to "services" and "module" is set to "popup_label_button") is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's 
browser session in context of an affected site.
