CVE-2022-22153— SRX Series and MX Series with SPC3: A high percentage of fragments might lead to high latency or packet drops

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 中存在资源管理错误漏洞，该漏洞源于产品SRX Series和MX Series与SPC3上的流处理守护进程的算法复杂度过低导致资源分配错误。攻击者可通过发送百分比大于5%的分片包导致传输包处理延迟、丢失并导致拒绝服务。

Vulnerability Title
SRX Series and MX Series with SPC3: A high percentage of fragments might lead to high latency or packet drops
Source: CVE Program / CVE List V5
Vulnerability Description
An Insufficient Algorithmic Complexity combined with an Allocation of Resources Without Limits or Throttling vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series and MX Series with SPC3 allows an unauthenticated network attacker to cause latency in transit packet processing and even packet loss. If transit traffic includes a significant percentage (> 5%) of fragmented packets which need to be reassembled, high latency or packet drops might be observed. This issue affects Juniper Networks Junos OS on SRX Series, MX Series with SPC3: All versions prior to 18.2R3; 18.3 versions prior to 18.3R3; 18.4 versions prior to 18.4R2-S9, 18.4R3; 19.1 versions prior to 19.1R2; 19.2 versions prior to 19.2R1-S1, 19.2R2.
