How the Exploit Works
This vulnerability stems from an improper neutralization of input during web page generation, commonly known as ‘Cross-site Scripting’ or XSS. In this case, the Drupal COOKiES Consent Management module is not correctly sanitizing user input. This allows an attacker to inject malicious scripts into a web page, which can then be executed in the context of the user’s browser session. This can lead to a range of nefarious outcomes, including unauthorized access to sensitive data, hijacking of the user’s session, or redirecting the user to malicious websites.
Conceptual Example Code
Here is a conceptual example of how an attacker might exploit this vulnerability. This would involve sending a specially crafted HTTP POST request to a vulnerable endpoint:
POST /cookie-consent HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "cookie-consent": "<script>malicious_code_here</script>" }In this example, the attacker includes a malicious script in the ‘cookie-consent’ field. If the application does not properly sanitize this input, the script will be rendered and executed when the web page is viewed by a user.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the vendor-supplied patch. This means upgrading to a version of Drupal COOKiES Consent Management that is 1.2.15 or later. For those who cannot immediately apply the patch, a web application firewall (WAF) or intrusion detection system (IDS) can be used as a temporary mitigation method. These systems can be configured to detect and block attempts to exploit this vulnerability. However, these are only temporary solutions and applying the vendor patch should be the ultimate goal.
