Drupal - Remote Code Execution (CVE-2018-7600)

Drupal is affected by a Remote Code Execution vulnerability, located on the /user/register endpoint. The root cause of this vulnerability consists in a lack of validation in API Ajax form which can be triggered for an OS Command Injection attack. Therefore, an unauthenticated remote attacker could send a crafted HTTP request in order to execute commands on the server.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

Upgrade Drupal to a version higher or equal of 7.58, 8.3.9, 8.4.6 or 8.5.1.
