Prior to 2.13.0, when dalfox is started in REST API server mode (dalfox server), the server binds to 0.0.0.0:6664 by default and requires no API key unless the operator explicitly passes --api-key. Because model.Options \u2014 including FoundAction and FoundActionShell \u2014 is deserialized directly from attacker-supplied JSON in POST /scan, and because dalfox.Initialize explicitly propagates those two fields into the final scan options without stripping them, any unauthenticated caller who can reach the server port can supply an arbitrary shell command that the dalfox process will execute on the host whenever a scan finding is triggered. This vulnerability is fixed in 2.13.0."}, {"lang": "es", "value": "Dalfox es un potente esc\u00e1ner XSS de c\u00f3digo abierto y una utilidad centrada en la automatizaci\u00f3n.
