好的，用户让我总结一下这篇文章的内容，控制在一百个字以内，而且不需要特定的开头。首先，我需要通读文章，抓住主要信息。 文章标题是Cisco修复了UCCX软件中的一个关键漏洞，允许执行Root命令。接下来，作者提到Cisco发布了安全更新，修复了CVE-2025-20354漏洞，CVSS评分9.8分。这个漏洞允许攻击者通过Java RMI上传文件并执行任意命令，获得root权限。 文章还提到这个漏洞存在于UCCX的Java远程方法调用过程中，由于身份验证机制不完善导致。Cisco已经发布了修复版本，并没有已知的野外攻击利用此漏洞。 总结的时候，我需要涵盖以下几点：Cisco修复了UCCX软件中的一个严重漏洞（CVE编号和CVSS评分），该漏洞允许攻击者通过Java RMI上传文件并以root权限执行命令。修复版本已经发布，并且目前没有已知的攻击案例。 现在我要把这些信息浓缩到100字以内。确保包含关键点：公司、产品、漏洞编号、CVSS评分、攻击方式、影响、修复情况以及是否有已知攻击。 可能的结构：Cisco修复了Unified Contact Center Express中的严重漏洞（CVE-2025-20354，CVSS 9.8），允许攻击者通过Java RMI上传文件并以root权限执行命令。已发布修复版本，尚未有野外攻击报告。 这样大约在100字左右，并且直接描述内容，符合用户的要求。 </think> Cisco修复了Unified Contact Center Express中的严重漏洞（CVE-2025-20354，CVSS 9.8），允许攻击者通过Java RMI上传文件并以root权限执行命令。已发布修复版本，尚未有野外攻击报告。 2025-11-7 11:37:10 Author: securityaffairs.com(查看原文) 阅读量:11 收藏
Cisco fixes critical UCCX flaw allowing Root command execution
Pierluigi Paganini
November 07, 2025
Cisco patched a critical flaw in its Unified Contact Center Express (UCCX) software that allowed attackers to execute commands with root privileges.
Cisco released security updates to address a critical vulnerability, tracked as CVE-2025-20354 (CVSS score 9.8), in the Unified Contact Center Express (UCCX) software. An attacker can exploit the flaw to execute commands with root privileges.
Cisco Unified Contact Center Express (UCCX) is a customer interaction management platform designed for small and medium-sized contact centers.
“A vulnerability in the Java Remote Method Invocation (RMI) process of Cisco Unified CCX could allow an unauthenticated, remote attacker to upload arbitrary files and execute arbitrary commands with root permissions on an affected system.” reads the advisory.
“This vulnerability is due to improper authentication mechanisms that are associated to specific Cisco Unified CCX features. An attacker could exploit this vulnerability by uploading a crafted file to an affected system through the Java RMI process. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.”
The flaw in Cisco Unified Contact Center Express’s Java RMI handling lets an unauthenticated remote actor upload files via the RMI interface and run commands as root. The root cause lies in improper or missing authentication tied to certain CCX features, so the RMI endpoint accepts and processes crafted input it should reject.
The networking giant states there are no workarounds that address this vulnerability, below are the fixed releases.
| Cisco Unified CCX Release | First Fixed Release |
|---|---|
| 12.5 SU3 and earlier | 12.5 SU3 ES07 |
| 15.0 | 15.0 ES01 |
The Cisco Product Security Incident Response Team (PSIRT) is not aware of attacks in the wild exploiting this vulnerability.
This week, Cisco warned of a new attack variant targeting vulnerable Secure Firewall ASA and FTD devices by exploiting the vulnerabilities CVE-2025-20333 and CVE-2025-20362.
