CriticalCVSS 9.8 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Plan (action score 42/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 9.1% (FIRST EPSS); higher than 95.3% 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.
  • Fixed version: zabbix (Debian:12) 1:4.0.0+dfsg-1; zabbix (Debian:9) 1:3.0.31+dfsg-0+deb9u1; zabbix (openSUSE:Leap 15.1) 3.0.31-bp152.2.3.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to zabbix (Debian:12) 1:4.0.0+dfsg-1; zabbix (Debian:9) 1:3.0.31+dfsg-0+deb9u1; zabbix (openSUSE:Leap 15.1) 3.0.31-bp152.2.3.1 or later.
