此问题被标记为CVE-2024-21591，在CVSS评分系统中得分为9.8。

"An out-of-bounds write vulnerability in J-Web of Juniper Networks Junos OS 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," the company said in an advisory.

"Juniper Networks Junos OS SRX系列和EX系列中J-Web的越界写漏洞允许未经身份验证的基于网络的攻击者在设备上造成拒绝服务（DoS）或远程代码执行（RCE）并获取根权限," 该公司在一份咨询中表示。

The networking equipment major, which is set to be acquired by Hewlett Packard Enterprise (HPE) for $14 billion, said the issue is caused by use of an insecure function allowing a bad actor to overwrite arbitrary memory.

这家网络设备巨头将被惠普企业（HPE）以140亿美元收购，该公司表示，该问题是由于使用不安全功能导致恶意操作者可以覆盖任意内存。

Also resolved by Juniper Networks is a high-severity bug in Junos OS and Junos OS Evolved (CVE-2024-21611, CVSS score: 7.5) that could be weaponized by an unauthenticated, network-based attacker to cause a DoS condition.

Juniper Networks也解决了Junos OS和Junos OS Evolved中的一个高严重性漏洞（CVE-2024-21611，CVSS得分：7.5），该漏洞可以被未经身份验证的基于网络的攻击者用于造成DoS状况。

While there is no evidence that the vulnerabilities are being exploited in the wild, multiple security shortcomings affecting the company's SRX firewalls and EX switches were abused by threat actors last year.

尽管没有证据表明这些漏洞在野外被利用，但去年威胁行为者滥用了影响公司SRX防火墙和EX交换机的多个安全缺陷。
