Sources and claim methodology

  • Source referencedocs.velociraptor.app
Upstream source description

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.
