Summary

The Communication Server in Alcatel-Lucent OmniPCX Enterprise 7.1 and earlier caches an IP address during a TFTP request from an IP Touch phone, and uses this IP address as the destination for all subsequent VoIP packets to this phone, which allows remote attackers to cause a denial of service (loss of audio) or intercept voice communications via a crafted TFTP request containing the phone's MAC address in the filename.

descriptionBUGTRAQ ID: 26494 CVE(CAN) ID: CVE-2007-5361 OmniPCX Enterprise是企业级的集成通讯解决方案。 OmniPCX Enterprise在处理畸形TFTP请求时存在漏洞，远程攻击者可能利用此漏洞导致设备工作不正常。 在引导时，OmniPCX Enterprise服务器的IP Touch电话会使用TFTP协议下载有关部署的配置信息。如果恶意用户能够向服务器发送恶意的TFTP请求，在文件名中包含受害用户VoIP电话的MAC地址，就可以将呼叫的音频流重新路由到自己计算机的IP地址。这时尽管VoIP电话仍可进行呼叫或应答，但无法听到通讯另一端的任何声音，必须手动重启VoIP电话才能恢复正常运行。此外，将音频流重新路由到攻击者的VoIP电话还可能导致窃听音频通讯。 Alcatel-Lucent OmniPCX Enterprise &lt;= 7.1 临时解决方法： * 在安装时将电话IP地址设置为不同于数据工作站的地址。 * 在通讯服务器前的防火墙过滤伪造的TFTP请求。 厂商补丁： Alcatel-Lucent -------------- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： <a href="http://www1.alcatel-lucent.com/enterprise/en/products/phones/index.html" target="_blank">http://www1.alcatel-lucent.com/enterprise/en/products/phones/index.html</a>
