Noroxi assessment

Priority: Now (action score 99/100)

  • CISA has confirmed exploitation in the wild (Apr 13, 2022); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: May 4, 2022.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 99.1% (FIRST EPSS); higher than 99.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: drupal7 (Alpine:v3.10) 7.59-r0; drupal7 (Debian:7) 7.14-2+deb7u19; drupal7 (Debian:8) 7.32-1+deb8u12.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Apr 13, 2022. That signals real attacks, not theory.

Remediation deadline for US federal agencies: May 4, 2022.

Known to be used in ransomware campaigns.
