Quick assessment
Affected
Juniper Networks Junos OS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Juniper Networks Junos OS是美国瞻博网络（Juniper Networks）公司的一套专用于该公司的硬件设备的网络操作系统。该操作系统提供了安全编程接口和Junos SDK。 Juniper Networks Junos OS 存在输入验证错误漏洞，该漏洞源于 VxLAN 数据包转发引擎 (PFE) 中存在不正确的输入验证漏洞，允许未经身份验证的相邻攻击者在同一 VxLAN 拓扑中发送两个或多个真实数据包，从而可能导致 DMA 内存损坏在各种特定的操作条件下都会发生泄漏。

Vulnerability Title
Junos OS: QFX5000 Series, EX4600 Series: In a VxLAN scenario an adjacent attacker within the VxLAN sending genuine packets may cause a DMA memory leak to occur.
Source: CVE Program / CVE List V5
Vulnerability Description
An Improper Input Validation vulnerability in the VxLAN packet forwarding engine (PFE) of Juniper Networks Junos OS on QFX5000 Series, EX4600 Series devices allows an unauthenticated, adjacent attacker, sending two or more genuine packets in the same VxLAN topology to possibly cause a DMA memory leak to occur under various specific operational conditions. The scenario described here is the worst-case scenario. There are other scenarios that require operator action to occur.
An indicator of compromise may be seen when multiple devices indicate that FPC0 has gone missing when issuing a show chassis fpc command for about 10 to 20 minutes, and a number of interfaces have also gone missing.
Use the following command to determine if FPC0 has gone missing from the device.
show chassis fpc detail
