Severity ?
4.0 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
A vulnerability in the IP geolocation rules of Snort 3 could allow an unauthenticated, remote attacker to potentially bypass IP address restrictions. This vulnerability exists because the configuration for IP geolocation rules is not parsed properly. An attacker could exploit this vulnerability by spoofing an IP address until they bypass the restriction. A successful exploit could allow the attacker to bypass location-based IP address restrictions.

Esta vulnerabilidad existe porque la configuraci\u00f3n de las reglas de geolocalizaci\u00f3n de IP no se analiza correctamente. Un atacante podr\u00eda aprovechar esta vulnerabilidad falsificando una direcci\u00f3n IP hasta omitir la restricci\u00f3n.
