Noroxi assessment

Priority: Now (action score 97/100)

  • CISA has confirmed exploitation in the wild (May 12, 2023). Remediation deadline for US federal agencies: Jun 2, 2023.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 92.3% (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-7 (Debian:7) 7u101-2.6.6-2~deb7u1; openjdk-7 (Debian:8) 7u101-2.6.6-1~deb8u1; java-1.6.0-openjdk (Red Hat:enterprise_linux:5::client) 1:1.6.0.39-1.13.11.0.el5_11.

Patch today or shut off access. Upgrade to openjdk-7 (Debian:7) 7u101-2.6.6-2~deb7u1; openjdk-7 (Debian:8) 7u101-2.6.6-1~deb8u1; java-1.6.0-openjdk (Red Hat:enterprise_linux:5::client) 1:1.6.0.39-1.13.11.0.el5_11 or later.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on May 12, 2023. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Jun 2, 2023.
