Noroxi assessment

Priority: Now (action score 98/100)

  • CISA has confirmed exploitation in the wild (Mar 3, 2022). Remediation deadline for US federal agencies: Mar 24, 2022.
  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 96.6% (FIRST EPSS); higher than 99.8% 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: openjdk-6 (Debian:5.0) 6b18-1.8.10-0~lenny2; openjdk-6 (Debian:6.0) 6b18-1.8.10-0+squeeze2; java-1.6.0-openjdk (Red Hat:enterprise_linux:5::client) 1:1.6.0.0-1.23.1.9.10.el5_7.

Patch today or shut off access. Upgrade to openjdk-6 (Debian:5.0) 6b18-1.8.10-0~lenny2; openjdk-6 (Debian:6.0) 6b18-1.8.10-0+squeeze2; java-1.6.0-openjdk (Red Hat:enterprise_linux:5::client) 1:1.6.0.0-1.23.1.9.10.el5_7 or later.

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

Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE JDK and JRE 7 and 6 Update 27 and earlier allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability via unknown vectors related to Scripting.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Mar 3, 2022. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Mar 24, 2022.
