Noroxi assessment

Priority: Monitor (action score 33/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 13.9% (FIRST EPSS); higher than 96.5% 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.
  • Fixed version: Advantech WISE-6610-NB 1.2.4_20260821.

Low priority for now. Upgrade to Advantech WISE-6610-NB 1.2.4_20260821 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability was identified in Advantech WISE-6610-NB, WISE-6610-EB, WISE-6610-TB, WISE-6610-JB, WISE-6610-CB, WISE-6610-EL-NB, WISE-6610-EL-EB, WISE-6610-EL-TB, WISE-6610-EL-JB, WISE-6610-EL-CB, WISE-6610P-DEA, WISE-6610P-DNA and WISE-6610P-DTA 1.2.1_20251110. Affected is an unknown function of the file /cgi-bin/luci/admin/openvpn_apply of the component Background Management. Such manipulation of the argument delete_file leads to os command injection. The attack can be executed remotely. The exploit is publicly available and might be used. Upgrading to version 1.2.4_20260821 is able to address this issue. It is advisable to upgrade the affected component. The vendor explains: "The delete operation has been redesigned to map the requested file type to a fixed allowlisted path, require a numeric tunnel ID, reject invalid requests, and use the native filesystem API (fs.unlink) instead of constructing a shell command from request data."
