Drupal core - Moderately critical - Access bypass - SA-CORE-2023-004
Project: Drupal core
Date: 2023-March-15
Security risk: Moderately critical 14â\x{136}\x{149}25
AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:Uncommon
Vulnerability: Access bypassAffected versions:
<7.95 || >=8.0.0 <9.4.12 || >=9.5.0 <9.5.5 || >=10.0.0 <10.0.5
Description:
Drupal core provides a page that outputs the markup from phpinfo() to assist
with diagnosing PHP configuration.
If an attacker was able to achieve an XSS exploit against a privileged user,
they may be able to use the phpinfo page to access sensitive information that
could be used to escalate the attack.
This vulnerability is mitigated by the fact that a successful XSS exploit is
required in order to exploit it.
Solution:
Install the latest version:
o If you are using Drupal 10.0, update to Drupal 10.0.5 .
o If you are using Drupal 9.5, update to Drupal 9.5.5 .
o If you are using Drupal 9.4, update to Drupal 9.4.12 .
o If you are using Drupal 7, update to Drupal 7.95 .
All versions of Drupal 9 prior to 9.4.x are end-of-life and do not receive
security coverage. Note that Drupal 8 has reached its end of life .
