MediumCVSS 6.1 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 2.9% (FIRST EPSS); higher than 87.3% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: wget (Alpine:v3.10) 1.19.1-r1; wget (Alpine:v3.2) 1.18-r1; wget (Alpine:v3.3) 1.17.1-r2.

Low priority for now. Upgrade to wget (Alpine:v3.10) 1.19.1-r1; wget (Alpine:v3.2) 1.18-r1; wget (Alpine:v3.3) 1.17.1-r2 or later.
