Descriptions
An Out-of-bounds Write vulnerability in J-Web of Juniper Networks Junos OS on SRX Series and EX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS), or Remote Code Execution (RCE) and obtain root privileges on the device.
This issue is caused by use of an insecure function allowing an attacker to overwrite arbitrary memory.
This issue affects Juniper Networks Junos OS SRX Series and EX Series:
* Junos OS versions earlier than 20.4R3-S9;
* Junos OS 21.2 versions earlier than 21.2R3-S7;
* Junos OS 21.3 versions earlier than 21.3R3-S5;
* Junos OS 21.4 versions earlier than 21.4R3-S5;
* Junos OS 22.1 versions earlier than 22.1R3-S4;
* Junos OS 22.2 versions earlier than 22.2R3-S3;
* Junos OS 22.3 versions earlier than 22.3R3-S2;
* Junos OS 22.4 versions earlier than 22.4R2-S2, 22.4R3.
Una vulnerabilidad de escritura fuera de los límites en J-Web de Juniper Networks Junos OS en las series SRX y EX permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS) o una ejecución remota de código (RCE) y obtenga privilegios de root en el dispositivo. Este problema se debe al uso de una función insegura que permite a un atacante sobrescribir la memoria arbitraria. Este problema afecta a las series Junos OS SRX y EX de Juniper Networks: * Versiones de Junos OS anteriores a 20.4R3-S9; * Versiones de Junos OS 21.2 anteriores a 21.2R3-S7; * Versiones de Junos OS 21.3 anteriores a 21.3R3-S5; * Versiones de Junos OS 21.4 anteriores a 21.4R3-S5; * Versiones de Junos OS 22.1 anteriores a 22.1R3-S4; * Versiones de Junos OS 22.2 anteriores a 22.2R3-S3; * Versiones de Junos OS 22.3 anteriores a 22.3R3-S2; * Versiones de Junos OS 22.4 anteriores a 22.4R2-S2, 22.4R3.
