Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.9% (FIRST EPSS); higher than 80.6% of all records.
  • Fixed version: dovecot (Debian:12) 1:1.0.10-1; dovecot (Debian:4.0) 1.0.rc15-2etch3; dovecot (Red Hat:enterprise_linux:5::client_workstation) 0:1.0.7-2.el5.

Low priority for now. Upgrade to dovecot (Debian:12) 1:1.0.10-1; dovecot (Debian:4.0) 1.0.rc15-2etch3; dovecot (Red Hat:enterprise_linux:5::client_workstation) 0:1.0.7-2.el5 or later.
