漏洞描述
中文描述:
Cisco Expressway Series和Cisco TelePresence Video Communication Server（VCS）都是美国思科（Cisco）公司的产品。Cisco Expressway Series是一款用于防火墙外访问设备的软件。该软件为防火墙外的用户提供了简单、高度安全的访问功能，帮助远程办公人员在他们选择的设备上更有效地工作。Cisco TelePresence Video Communication Server是一款视频通信服务器。 Cisco Expressway 系列和Cisco TelePresence Video Communication Server存在安全漏洞，该漏洞源于软件中的web管理界面对上传到设备的一些特制的软件镜像处理不当造成的。攻击者可以通过以管理用户身份对系统进行身份验证，然后将特制的软件镜像上传到受影响的设备来利用此漏洞。 漏洞可能允许攻击者以 root 用户身份在底层操作系统上执行任意代码。
英文描述:
A vulnerability in the web-based management interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to execute arbitrary code on the underlying operating system as the root user. This vulnerability is due to incorrect handling of certain crafted software images that are uploaded to the affected device. An attacker could exploit this vulnerability by authenticating to the system as an administrative user and then uploading specific crafted software images to the affected device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system as the root user.
