Noroxi assessment

Priority: Monitor (action score 4/100)

  • 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: 0.69% (FIRST EPSS); higher than 53.4% of all records.
  • Special conditions such as timing or configuration are required.
  • Fixed version: proftpd-dfsg (Debian:12) 1.3.4a-3; proftpd-dfsg (Debian:6.0) 1.3.3a-6squeeze6.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to proftpd-dfsg (Debian:12) 1.3.4a-3; proftpd-dfsg (Debian:6.0) 1.3.3a-6squeeze6 or later.
