CVE-2018-7602 Drupal CVE debrief

Who should care

Drupal administrators, application owners, web platform teams, managed service providers, and security teams responsible for internet-facing web applications or shared hosting environments.

Technical summary

The available official records identify the issue as a Drupal Core remote code execution vulnerability. The CISA KEV entry lists Drupal as the vendor project, Core as the product, and notes known ransomware campaign use. The supplied source corpus does not include exploit mechanics, affected version ranges, or patch specifics, so defenders should rely on the vendor’s remediation guidance and confirm that all Drupal Core deployments are updated.

Defensive priority

High. CISA has included this CVE in the Known Exploited Vulnerabilities catalog and flagged known ransomware campaign use, which indicates active real-world abuse and a strong need for prompt patching.

Recommended defensive actions

• Inventory all Drupal Core deployments, including public-facing sites and non-production instances.
• Apply the vendor’s updates and remediation guidance as soon as possible.
• Confirm that every instance is patched, not just the primary production system.
• Prioritize systems exposed to the internet or supporting critical business services.
• Review authentication, access, and web server logs for suspicious activity around affected systems.
• Validate that asset and vulnerability management records reflect completion of remediation.
