CVE-2018-7602: Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-004

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.

Security readout for executives and security teams

Plain-English summary

CVE-2018-7602 is a critical Drupal core remote code execution flaw. An unauthenticated attacker could compromise a vulnerable Drupal site over the network. The provided sources state this issue was exploited in the wild, and CISA lists it in KEV, so exposed legacy Drupal assets should be treated as urgent.

Executive priority

Treat this as an immediate remediation and compromise-assessment item for any exposed Drupal 7.x or 8.x asset. The combination of unauthenticated RCE, known exploitation, and public exploit references makes delayed action high risk.

Technical view

The vulnerability affects multiple Drupal 7.x and 8.x subsystems and is related to SA-CORE-2018-002. It is classified as CWE-94 with CVSS 9.8: network-accessible, low complexity, no privileges, no user interaction, and high confidentiality, integrity, and availability impact.

Likely exposure

Most likely exposure is internet-facing Drupal 7.x or 8.x sites that did not receive Drupal or downstream distribution security updates for SA-CORE-2018-004. The source bundle does not provide exact affected or fixed version ranges.

Exploitation context

Active exploitation is supported by the CVE description and CISA KEV listing. Exploit-DB references indicate public exploit material exists, increasing risk for unpatched public Drupal sites. No offensive procedure is needed to assess business urgency.

Researcher notes

Evidence is strong for severity and exploitation, but the provided bundle does not specify fixed Drupal versions or complete CPE mappings. Use Drupal SA-CORE-2018-004 and distribution advisories as authoritative remediation references.

Mitigation direction

  • Inventory all Drupal 7.x and 8.x sites, including legacy and archived web properties.
  • Apply Drupal SA-CORE-2018-004 guidance and relevant Debian security updates where applicable.
  • Prioritize internet-facing Drupal systems and sites handling credentials, payments, or sensitive content.
  • If update status is uncertain, isolate the site or restrict public access pending validation.
  • Review vendor guidance before assuming any workaround is sufficient.

Validation and detection

  • Confirm each Drupal deployment version and whether SA-CORE-2018-004 remediation was applied.
  • Check package records for Debian DSA-4180 or DLA-1365-1 where Drupal came from Debian.
  • Search web logs around exposure windows for suspicious Drupal request patterns and unexpected code execution indicators.
  • Verify no unknown modules, users, scheduled tasks, or file changes appeared after suspected exposure.
  • Confirm CISA KEV tracking has been incorporated into vulnerability management prioritization.

Improper Control of Generation of Code ('Code Injection')

Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
