HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 4% (FIRST EPSS); higher than 90.8% 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: libdbd-mysql-perl (Debian:12) 4.037-1; libdbd-mysql-perl (Debian:7) 4.021-1+deb7u2; libdbd-mysql-perl (Debian:8) 4.028-2+deb8u2.

Low priority for now. Upgrade to libdbd-mysql-perl (Debian:12) 4.037-1; libdbd-mysql-perl (Debian:7) 4.021-1+deb7u2; libdbd-mysql-perl (Debian:8) 4.028-2+deb8u2 or later.
