How the Exploit Works
This vulnerability is a classic example of Cross-site Scripting (XSS), where the Drupal COOKiES Consent Management fails to neutralize user input during web page generation properly. An attacker can exploit this flaw by injecting malicious script into the website which is then executed in the browser of any user visiting the infected webpage. This malicious script can potentially compromise the user’s system or lead to data leakage.
Conceptual Example Code
A conceptual exploit might involve an HTTP POST request to a vulnerable endpoint on the Drupal COOKiES Consent Management system. The malicious payload would be inserted into a field that is not correctly sanitized by the system. An example of such a request could look like this:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "user_input_field": "<script>malicious_script_here</script>" }In the above example, the “user_input_field” could be any field in the system that is vulnerable to XSS injection. The “malicious_script_here” would be replaced with the actual malicious code that the attacker wants to execute on the victim’s browser.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as possible. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. These systems can be configured to detect and block attempts to exploit this vulnerability, providing a stopgap until the patch can be applied.
