Description

Deserialization of Untrusted Data vulnerability in Drupal Core allows Object Injection.This issue affects Drupal Core: from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9, from 11.0.0 before 11.0.8.

Drupal core contains a chain of methods that is exploitable when an insecure deserialization vulnerability exists on the site. This so called gadget chain presents no direct threat, but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability.

Drupal core contains a potential PHP Object Injection vulnerability

GHSA-938f-5r4f-h65v

Advisory Details

Drupal core contains a potential PHP Object Injection vulnerability that (if combined with another exploit) could lead to Artbitrary File Deletion. It is not directly exploitable. This issue is mitigated by the fact that in order to be exploitable, a separate vulnerability must be present that allows an attacker to pass unsafe input to `unserialize()`. There are no such known exploits in Drupal core. To help protect against this vulnerability, types have been added to properties in some of Drupal core's classes. If an application extends those classes, the same types may need to be specified on the subclass to avoid a `TypeError`. This issue affects Drupal Core: from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9, from 11.0.0 before 11.0.8.
