When combined with other vulnerabilities, such as CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177, an attacker can execute arbitrary commands remotely on the target machine without authentication when a malicious printer is printed to."}, {"lang": "es", "value": "CUPS es un sistema de impresi\u00f3n de c\u00f3digo abierto basado en est\u00e1ndares, y `cups-browsed` contiene funcionalidades de impresi\u00f3n en red que incluyen, entre otras, servicios de impresi\u00f3n de detecci\u00f3n autom\u00e1tica e impresoras compartidas. `cups-browsed` se vincula a `INADDR_ANY:631`, lo que hace que conf\u00ede en cualquier paquete de cualquier origen, y puede provocar la solicitud IPP `Get-Printer-Attributes` a una URL controlada por el atacante. Debido a la vinculaci\u00f3n del servicio a `*:631 ( INADDR_ANY )`, se pueden explotar varios errores en `cups-browsed` en secuencia para introducir una impresora maliciosa en el sistema. Esta cadena de exploits finalmente permite a un atacante ejecutar comandos arbitrarios de forma remota en la m\u00e1quina de destino sin autenticaci\u00f3n cuando se inicia un trabajo de impresi\u00f3n. Esto plantea un riesgo de seguridad significativo en la red. Cabe destacar que esta vulnerabilidad es particularmente preocupante ya que se puede explotar desde Internet p\u00fablico, lo que potencialmente expone una gran cantidad de sistemas a ataques remotos si sus servicios CUPS est\u00e1n habilitados."}], "lastModified": "2024-11-21T09:39:28.853", "sourceIdentifier": "security-advisories@github.com"}
