Die Entwickler des Open-Source CMS, Drupal, haben ein Security Update für die Zweige 7.x und 8.x veröffentlicht. Da mit diesem 4 kritische Sicherheitslücken geschlossen werden, sollte das Update umgehen durchgeführt werden. Betroffen sind alle Version vor 7.52 und 8.2.3.
Drupal 7.52 Release
Inconsistent name for term access query (Less critical – Drupal 7 and Drupal 8)
Drupal provides a mechanism to alter database
SELECT queries before they are executed. Contributed and custom modules may use this mechanism to restrict access to certain entities by implementing
hook_query_TAG_alter() in order to add additional conditions. Queries can be distinguished by means of query tags. As the documentation on EntityFieldQuery::addTag() suggests, access-tags on entity queries normally follow the form
node_access). However, the taxonomy module’s access query tag predated this system and used
term_access as the query tag instead of
As a result, before this security release modules wishing to restrict access to taxonomy terms may have implemented an unsupported tag, or needed to look for both tags (
taxonomy_term_access) in order to be compatible with queries generated both by Drupal core as well as those generated by contributed modules like Entity Reference. Otherwise information on taxonomy terms might have been disclosed to unprivileged users.
Incorrect cache context on password reset page (Less critical – Drupal 8)
The user password reset form does not specify a proper cache context, which can lead to cache poisoning and unwanted content on the page.
Confirmation forms allow external URLs to be injected (Moderately critical – Drupal 7)
Under certain circumstances, malicious users could construct a URL to a confirmation form that would trick users into being redirected to a 3rd party website after interacting with the form, thereby exposing the users to potential social engineering attacks.
Denial of service via transliterate mechanism (Moderately critical – Drupal 8)
A specially crafted URL can cause a denial of service via the transliterate mechanism.
