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 Series 和 Cisco TelePresence Video Communication Server (VCS)存在数据伪造问题漏洞，该漏洞源于对升级包内容的验证不足。该漏洞可能允许经过身份验证的远程攻击者在底层操作系统上以内部用户权限执行代码。
英文描述:
A vulnerability in the image verification function of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to execute code with internal user privileges on the underlying operating system. The vulnerability is due to insufficient validation of the content of upgrade packages. An attacker could exploit this vulnerability by uploading a malicious archive to the Upgrade page of the administrative web interface. A successful exploit could allow the attacker to execute code with user-level privileges (the _nobody account) on the underlying operating system.
