Cross-site Scripting occurrences in Commerce Cloud
When SAP Commerce Cloud version 100, hosts a JavaScript storefront, it is vulnerable to MIME sniffing, which, in certain circumstances, could be used to facilitate an XSS attack or malware proliferation. (2021-06-09, CVE-2021-33666)
SAP Commerce Cloud versions - 1808, 1811, 1905, 2005, does not sufficiently encode user inputs, which allows an authenticated and authorized content manager to inject malicious script into several web CMS components. These can be saved and later triggered, if an affected web page is visited, resulting in Cross-Site Scripting (XSS) vulnerability. (2020-10-15, CVE-2020-6272)
The SAP Commerce (SmartEdit Extension), versions- 6.6, 6.7, 1808, 1811, is vulnerable to client-side angularjs template injection, a variant of Cross-Site-Scripting (XSS) that exploits the templating facilities of the angular framework. (2020-03-10, CVE-2020-6200)
The SAP Commerce (Testweb Extension), versions- 6.6, 6.7, 1808, 1811, 1905, does not sufficiently encode user-controlled inputs, due to which certain GET URL parameters are reflected in the HTTP responses without escaping/sanitization, leading to Reflected Cross Site Scripting. (2020-03-10, CVE-2020-6201)
Why Cross-site Scripting can be dangerous
Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.
The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:
https://server.com/confirmation?message=Transaction+Complete
what results in:
<span>Confirmation: Transaction Complete</span>
In that case the message can be modified to become a valid Javascript code, e.g.:
https://server.com/confirmation?message=<script>dangerous javascript code here</script>
and it will be executed locally by the user's browser with full access to the user's personal application/browser data:
<span>Confirmation: <script>dangerous javascript code here</script></span>
