CVE-2023-0861: Authenticated Command Injection in NetModule NSRW

Noroxi assessment

Priority: Plan (action score 44/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 28.6% (FIRST EPSS); higher than 98.1% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: NetModule NSRW 4.3.0.119, 4.4.0.118, 4.6.0.105.

Add it to your regular patch cycle. Upgrade to NetModule NSRW 4.3.0.119, 4.4.0.118, 4.6.0.105 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

NetModule NSRW web administration interface executes an OS command constructed with unsanitized user input. A successful exploit could allow an authenticated user to execute arbitrary commands with elevated privileges. This issue affects NSRW: from 4.3.0.0 before 4.3.0.119, from 4.4.0.0 before 4.4.0.118, from 4.6.0.0 before 4.6.0.105, from 4.7.0.0 before 4.7.0.103.
