Summary

Open Redirect vulnerability in Drupal Core allows a user to be tricked into visiting a specially crafted link which would redirect them to an arbitrary external URL. This issue affects: Drupal Drupal Core 7 version 7.70 and prior versions.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Fake the Source of Data
    An adversary provides data under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or it might be an attempt by the adversary to assume the rights granted to another identity. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.
