CVE-2022-25271 describes an improper input validation vulnerability within Drupal core's form API. Certain contributed or custom modules' forms may be vulnerable, potentially allowing attackers to inject disallowed values or overwrite data, leading to altered critical or sensitive information. This affects Drupal Core versions 9.3.5 and earlier. The vulnerability is fixed in Drupal version 9.3.6.
CVE-2022-25271 in Drupal core affects the Form API, allowing attackers to inject disallowed values or overwrite data within specific forms of contributed or custom modules. While affected forms are uncommon, in certain cases, an attacker could alter critical or sensitive data. The risk stems from inadequate user input validation in some instances, potentially leading to application logic manipulation. The severity of the impact depends on the nature of the data that can be manipulated and the access an attacker might gain as a result. Upgrading to version 9.3.6 or later is strongly recommended to mitigate this risk. Failure to update could expose your website to targeted attacks, compromising data integrity and confidentiality.
Exploitation of CVE-2022-25271 requires an attacker to be able to interact with a specific vulnerable form within a contributed or custom module. This implies the attacker must have access to the website and the ability to submit data through the form. The success of exploitation depends on the form's configuration and the input validation implemented. An attacker might use techniques like code injection or parameter manipulation to alter the data processed by the form. The complexity of exploitation varies depending on the affected module and the nature of the vulnerability. It's important to note that successful exploitation of this vulnerability could allow an attacker to gain unauthorized access to sensitive data or perform unauthorized actions on the website.

The primary solution for mitigating CVE-2022-25271 is to update Drupal Core to version 9.3.6 or later. This update includes the necessary fixes to address the input validation vulnerability. Additionally, review contributed and custom modules that utilize the Form API to ensure they implement robust input validation. Thorough testing of forms after the update is crucial to confirm the vulnerability has been effectively mitigated and that website functionality remains unaffected. Implementing a security policy that includes input validation in all forms is a recommended practice to prevent future similar vulnerabilities. Monitoring server logs for suspicious activity can also help detect and respond to potential attacks.
Update Drupal core to the latest version. Specifically, update to version 9.3.6, 9.2.13, or 7.88, depending on the version of Drupal you are using. This will correct the input validation vulnerability in the form API.
Vulnerability analysis and critical alerts directly to your inbox.
Modules that utilize the Form API and do not implement robust input validation are most likely to be affected. It's important to review the contributed and custom modules used by your website.
If you cannot update immediately, consider temporarily disabling modules that utilize the Form API until you can apply the update. Implement firewall rules to restrict access to vulnerable forms.
The safest way is to update to version 9.3.6 or later. You can also perform a security audit to identify potential vulnerabilities in your forms.
There are security analysis tools that can help identify vulnerable forms on your website. Consult with a security professional for recommendations.
Depending on the form, compromised data could include personal information, user credentials, configuration data, or any other data processed through the form.
