Noroxi assessment

Priority: Now (action score 92/100)

  • CISA has confirmed exploitation in the wild (Mar 25, 2022); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Apr 15, 2022.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 99.7% (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. Special conditions such as timing or configuration are required.
  • Fixed version: org.apache.tomcat.embed:tomcat-embed-core (Maven) 7.0.79; tomcat6 (Red Hat:enterprise_linux:6::client) 0:6.0.24-111.el6_9; tomcat6-admin-webapps (Red Hat:enterprise_linux:6::client) 0:6.0.24-111.el6_9.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Patch today or shut off access. Upgrade to org.apache.tomcat.embed:tomcat-embed-core (Maven) 7.0.79; tomcat6 (Red Hat:enterprise_linux:6::client) 0:6.0.24-111.el6_9; tomcat6-admin-webapps (Red Hat:enterprise_linux:6::client) 0:6.0.24-111.el6_9 or later.

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

When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Mar 25, 2022. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Apr 15, 2022.

Known to be used in ransomware campaigns.
