Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 1.4% (FIRST EPSS); higher than 74.4% 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: erlang (Alpine:v3.16) 24.3.4.6-r0; erlang (Alpine:v3.17) 25.0.3-r0; erlang26 (Alpine:v3.22) 25.0.3-r0.

Low priority for now. Upgrade to erlang (Alpine:v3.16) 24.3.4.6-r0; erlang (Alpine:v3.17) 25.0.3-r0; erlang26 (Alpine:v3.22) 25.0.3-r0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In Erlang/OTP before 23.3.4.15, 24.x before 24.3.4.2, and 25.x before 25.0.2, there is a Client Authentication Bypass in certain client-certification situations for SSL, TLS, and DTLS.
