Synopsis

A PHP application running on the remote web server is affected by multiple vulnerabilities.

Description

According to its self-reported version, the instance of Drupal running on the remote web server is 10.4.x prior to 10.4.9, 10.5.x prior to 10.5.6, 11.1.x prior to 11.1.9, or 11.2.x prior to 11.2.8. It is, therefore, affected by multiple vulnerabilities.

- 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. It is not directly exploitable. This issue is mitigated by the fact that in order for it to be exploitable, a separate vulnerability must be present to allow an attacker to pass unsafe input to unserialize(). There are no such known exploits in Drupal core. (CVE-2025-13081)

- The core system module handles downloads of private and temporary files. Contrib modules can define additional kinds of files (schemes) that may also be handled by the system module. In some cases, files may be served with the HTTP header Cache-Control: public when they should be uncacheable. This can lead to some users getting cached versions of files with information they should not be able to access. For example, files may be cached by Varnish or a CDN. This vulnerability is mitigated by the following: Drupal must be configured to handle non-public files using a custom or contributed module providing an additional file scheme. An attacker must know to request a file that has previously been requested by a more- privileged user, and that file must still be cached. (CVE-2025-13083)

- By generating and tricking a user into visiting a malicious URL, an attacker can perform site defacement.
The defacement is not stored and is only present when the URL has been crafted for that purpose. Only the defacement is present, so no other site content (such as branding) is rendered. (CVE-2025-13082)

- Drupal Core has a rarely used feature, provided by an underlying library, which allows certain attributes of incoming HTTP requests to be overridden. This functionality can be abused in a way that may cause Drupal to cache response data that it should not. This can lead to legitimate requests receiving inappropriate cached responses (cache poisoning). This could be exploited in various ways: Broken rendering of some pages Unstyled or malformatted pages Adverse impacts on client-side functionality Changes are being made in the underlying library which will mitigate this problem, but in the meantime Drupal core has been hardened to protect against this vulnerability. (CVE-2025-13080)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Drupal version 10.4.9 / 10.5.6 / 11.1.9 / 11.2.8 or later.
