CriticalCVSS 9.2 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 36/100)

  • 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: 0.37% (FIRST EPSS).
  • 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: AxxonSoft Axxon One 3.0.0.

Low priority for now. Upgrade to AxxonSoft Axxon One 3.0.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Use of Default Password (CWE-1393) in the web client in AxxonSoft Axxon One before 3.0.0 on Windows and Linux allows a remote unauthenticated attacker to log in as the built-in administrator with the default credentials on a newly installed system, because the web client did not enforce the mandatory change of the default password on first login.
