Noroxi assessment

Priority: Monitor (action score 32/100)

  • 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: 0.36% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Rapid7 Velociraptor 0.77.2.

Low priority for now. Upgrade to Rapid7 Velociraptor 0.77.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Velociraptor's web GUI allows specifying a custom type for columns in tables. The URL type takes the cell value and forms a URL which can be clicked in the GUI.The code does not limit the schemes allowed in this URL , allowing an attacker to specify a JavaScript scheme exposing the user to XSS.
