Drupal has made it to the news this week as it addressed numerous security flaws affecting its platform. In brief, Drupal patched three different vulnerabilities, including two critical ones, as it released its updated versions.
Critical Code Execution Drupal Vulnerabilities
Drupal has recently addressed a critical security flaw affecting numerous versions of the platform.
Describing the details in their advisory, the developers explained that a critical arbitrary PHP code execution flaw affected their platform. Under certain conditions, it became possible for a potential attacker to exploit the bug and execute malicious codes.
An attacker could trick an administrator into visiting a malicious site that could result in creating a carefully named directory on the file system. With this directory in place, an attacker could attempt to brute force a remote code execution vulnerability.
Besides, there also existed a critical severity CSRF bug affecting Drupal 7, 8, and 9. This bug existed due to improper handling of form inputs from cross-site requests by Drupal core Form API. As explained in the advisory, exploiting this bug could also lead to other security flaws.
The developers also addressed this bug with the release of Drupal 7.72, 8.8.8, 8.9.1, and 9.0.1, respectively.
Users of the respective Drupal versions should update to the corresponding patched version to fix the flaws.
Less Critical Drupal Flaw Also Received A Fix
Apart from the two critical bugs, Drupal also released a fix for a less critical access bypass vulnerability. Describing this flaw, Drupal stated in the advisory,
JSON:API PATCH requests may bypass validation for certain fields.
By default, JSON:API works in a read-only mode which makes it impossible to exploit the vulnerability. Only sites that have the
jsonapi.settingsconfig are vulnerable.
Drupal is a popular CMS after WordPress that has gained traction due to its robust security.
Certainly, Drupal makes sure to keep up with the expected level of security by proactively identifying and fixing security flaws. Now, it remains the responsibility of the users to keep their software versions updated to avoid any potential exploits.
