CVE-2018-7600
Published: 29 March 2018
Summary
CVE-2018-7600 is a critical-severity Improper Input Validation (CWE-20) vulnerability in Drupal Drupal. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2018-7600 is a remote code execution vulnerability affecting Drupal versions prior to 7.58, 8.x before 8.3.9, 8.4.x before 8.4.6, and 8.5.x before 8.5.1. The flaw stems from an input validation issue (CWE-20) impacting multiple subsystems when default or common module configurations are in use, enabling unauthenticated attackers to inject and execute arbitrary code on the server.
The vulnerability can be exploited remotely over the network by unauthenticated attackers without user interaction, as reflected in its CVSS 3.1 score of 9.8. Successful exploitation grants full control over the affected Drupal installation, allowing arbitrary code execution that can lead to complete compromise of confidentiality, integrity, and availability.
Advisories and references, including Drupal security announcement SA-CORE-2018-002, direct users to apply the listed version updates to remediate the issue. Public references also note the availability of proof-of-concept code and scanning data indicating more than 100,000 exposed Drupal sites at the time of disclosure.
The issue, sometimes referred to as Drupalgeddon 2, saw rapid public analysis and exploit development following its 2018 publication, consistent with the provided references to vulnerability scanners and exploit repositories.
