Nortel and Polycom have announced IP phone support for Microsoft's Unified Communications Platform 2007.

LG-Nortel, a joint venture of LG Electronics Nortel, will develop and market a business-enabled IP desktop phone that will work with Microsoft Office Communications Server 2007 and incorporate presence-awareness, IP call management features, and enhanced instant messaging capabilities. Both Microsoft and LG-Nortel will market the new phones to Microsoft customers worldwide starting in 2007.

Polycom also announced support for Microsoft's plan for unified communication and will develop and market integrated business-class UC SIP "voice end-points," with the new products incorporating integrated desktop devices to leverage presence awareness, IM, and the new telephony and VoIP capabilities of Microsoft's unified communications platform. The new devices will also support wideband voice communications at 14 kHz, auto provisioning, management, and configuration.

Cisco Wednesday revealed details on two vulnerabilities that could enable remote attackers to gain unauthorized administrative access to wireless LANs.
The first affects Cisco's Wireless Control System (WCS), an application for managing lightweight access points and WLAN controllers.

Cisco Wednesday issued an advisory outlining numerous vulnerabilities in WCS that could enable remote users to perform a wide range of malicious acts, such as logging in with a default password, obtaining access point encryption keys, launching cross-site scripting attacks, and reading and writing to files in the WCS system.

In an advisory issued Wednesday to subscribers of DeepSight Threat Management System, Symantec rated the severity of the flaw as 8.9 on a 10 point scale and said the vulnerabilities only require access to the WCS application in order to be exploited.

A second flaw that came to light Wednesday involves an issue in the Cisco Access Point Web interface that could enable remote attackers to bypass authentication and gain access to the administrative interface.

In a separate advisory, Symantec gave this issue its highest severity rating, 10 out of 10. The Cupertino, Calif.-based security vendor outlined an attack scenario in which an attacker could find a remotely accessible access point with its Web interface enabled, connect to the interface without logging in, and gain full administrative privileges to the access point and possibly use it to launch subsequent attacks.

As a workaround in the meantime, Cisco recommends disabling Web-based management. The issue only affects Cisco Access Points running Cisco IOS Software Release 12.3(8)JA or 12.3(8)JA1.

San Jose, Calif.-based Cisco issued advisories for both vulnerabilities and said it will release free software to its affected customers.
