Noroxi assessment

Priority: Now (action score 100/100)

  • CISA has confirmed exploitation in the wild (Mar 28, 2022). Remediation deadline for US federal agencies: Apr 18, 2022.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 99.3% (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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: redis (Debian:10) 5:5.0.14-1+deb10u2; redis (Debian:11) 5:6.0.16-1+deb11u2; redis (Debian:12) 5:6.0.16-2.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Patch today or shut off access. Upgrade to redis (Debian:10) 5:5.0.14-1+deb10u2; redis (Debian:11) 5:6.0.16-1+deb11u2; redis (Debian:12) 5:6.0.16-2 or later.
