Description
Description
An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a limited information disclosure and availability impact to the device.
Due to a wrong initialization, a process which should only be able to communicate internally within the device can be reached over the network via an open port. This leads to a device being inadvertently exposed and increased CPU cycles spent processing ingress packets.
This issue affects Junos OS Evolved:
* All versions before 23.2R2-S7.7-EVO;
* 23.4 versions before 23.4R2-S8.11-EVO;
* 24.2 versions before 24.2R2-S5.6-EVO;
* 24.4 versions before 24.4R2-S4-EVO;
* 25.2 version before 25.2R2-S1-EVO;
* 25.4 versions before 25.4R1-S1-EVO.
