CVE-2024-39280: An external config control vulnerability exists in the nas.cgi set_smb_cfg() functionality of Wavlink AC3000 M33A8.V5030.210505.

Noroxi assessment

Priority: Plan (action score 46/100)

  • 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: 34.9% (FIRST EPSS); higher than 98.4% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
