CVE-2013-4225Network attack vector

Authenticated code execution via unchecked entity writes

Published Feb 11, 2020 · Updated Aug 6, 2024

Cross-site scripting and PHP code execution in OAuth.js RESTful Web Services before 7.x-1.4 or 7.x-2.1 allow remote authenticated users via crafted text fields. RESTWS fails to enforce field-level authorization on entity write operations, allowing a user with resource-access and content-creation permissions to submit malicious text. Exploitation requires those permissions and a reachable Drupal RESTWS endpoint; consequences include stored script execution or arbitrary PHP execution through the submitted field.
