Drupal issued a security advisory (SA-CORE-2018-004) on Wednesday to address a Highly Critical Remote Code Execution vulnerability (CVE-2018-7602).
It is important to note this vulnerability is being exploited in the wild.
An excerpt from the advisory:
“A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple attack vectors on a Drupal site, which could result in the site being compromised. This vulnerability is related to Drupal core – Highly critical – Remote Code Execution – SA-CORE-2018-002. Both SA-CORE-2018-002 and this vulnerability are being exploited in the wild.”
Admins are highly advised to update their systems with the latest version of Drupal 7 or 8 core:
- If you are running 7.x, upgrade to Drupal 7.59.
- If you are running 8.5.x, upgrade to Drupal 8.5.3.
- If you are running 8.4.x, upgrade to Drupal 8.4.8 (then update to 8.5.3)
It is also important to note that 8.4.x is no longer supported, but Drupal is providing updates given the severity of the issue and known exploits in the wild.
