CVE-2019-1845 (CNNVD-201906-159)
中文标题:
多款Cisco产品输入验证错误漏洞
英文标题:
Cisco Unified Communications Manager IM&P Service, Cisco TelePresence VCS, and Cisco Expressway Series Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Expressway Series等都是美国思科（Cisco）公司的产品。Cisco Expressway Series是一款用于统一通信的高级协作网关。Cisco TelePresence Video Communication Server（VCS）是一款视频通信服务器。Cisco Unified Communications Manager（CUCM，Unified CM，CallManager）是一款统一通信系统中的呼叫处理组件。 多款Cisco产品中的身份验证服务存在输入验证错误漏洞。该漏洞源于网络系统或产品未对输入的数据进行正确的验证。以下产品及版本受到影响：Cisco Expressway Series configured for Mobile and Remote Access with IM&P Service X8.1版本至X12.5.2版本；TelePresence VCS configured for Mobile and Remote Access with IM&P Service X8.1版本至12.5.2版本；Unified Communications Manager IM&P Service。
英文描述:
A vulnerability in the authentication service of the Cisco Unified Communications Manager IM and Presence (Unified CM IM&P) Service, Cisco TelePresence Video Communication Server (VCS), and Cisco Expressway Series could allow an unauthenticated, remote attacker to cause a service outage for users attempting to authenticate, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient controls for specific memory operations. An attacker could exploit this vulnerability by sending a malformed Extensible Messaging and Presence Protocol (XMPP) authentication request to an affected system. A successful exploit could allow the attacker to cause an unexpected restart of the authentication service, preventing users from successfully authenticating. Exploitation of this vulnerability does not impact users who were authenticated prior to an attack.
