CVE-2024-47502

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-47502
An Allocation of Resources Without Limits or Throttling vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS). In specific cases the state of TCP sessions that are terminated is not cleared, which over time leads to an exhaustion of resources, preventing new connections to the control plane from being established. A continuously increasing number of connections shown by: user@host > show system connections is indicative of the problem. To recover the respective RE needs to be restarted manually. This issue only affects IPv4 but does not affect IPv6. This issue only affects TCP sessions established in-band (over an interface on an FPC) but not out-of-band (over the management ethernet port on the routing-engine). This issue affects Junos OS Evolved:  * All versions before 21.4R3-S9-EVO, * 22.2 versions before 22.2R3-S4-EVO, * 22.4 version before 22.4R3-S3-EVO, * 23.2 versions before 23.2R2-S1-EVO, * 23.4 versions before 23.4R2-EVO.

Summary
  • (es) Una vulnerabilidad de asignación de recursos sin límites o limitación en el núcleo de Juniper Networks Junos OS Evolved permite a un atacante no autenticado basado en la red provocar una denegación de servicio (DoS). En casos específicos, el estado de las sesiones TCP que se terminan no se borra, lo que con el tiempo conduce a un agotamiento de los recursos, lo que impide que se establezcan nuevas conexiones al plano de control. Un número de conexiones en continuo aumento que se muestra mediante: user@host > show system connections es indicativo del problema. Para recuperarse, es necesario reiniciar manualmente el RE correspondiente. Este problema solo afecta a IPv4, pero no a IPv6. Este problema solo afecta a las sesiones TCP establecidas en banda (a través de una interfaz en un FPC), pero no fuera de banda (a través del puerto Ethernet de administración en el motor de enrutamiento). Este problema afecta a Junos OS Evolved: * Todas las versiones anteriores a 21.4R3-S9-EVO, * Versiones 22.2 anteriores a 22.2R3-S4-EVO, * Versiones 22.4 anteriores a 22.4R3-S3-EVO, * Versiones 23.2 anteriores a 23.2R2-S1-EVO, * Versiones 23.4 anteriores a 23.4R2-EVO.
