Noroxi assessment

Priority: This week (action score 75/100)

  • CISA has confirmed exploitation in the wild (Mar 31, 2022). Remediation deadline for US federal agencies: Apr 21, 2022.
  • Probability of exploitation in the next 30 days: 19.4% (FIRST EPSS); higher than 97.3% 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.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
