voip testingConformance testing voipCisco Systems has disclosed that a core component of its enterprise VOIP system is vulnerable to several serious security flaws. The flaws could allow remote attackers to compromise a company's VOIP network, redirect or listen in on calls and carry out other nastiness, according to Cisco and Internet Security Systems (ISS), which VoIP Main Page discovered the flaws. While the bugs conformance testing voip haven't yet been exploited, they represent one of the most high-profile security scares in enterprise IP telephony to date. Enterprises are moving quickly to shift to IP-based telephone networks, with Gartner predicting that by 2007, 97 percent of new enterprise phone systems Performance testing voipinstalled in North America will VoIP Main Page be either VOIP or hybrid. Cisco leads the market at the moment performance testing voip by a wide margin, with a 42 percent share in North America, followed by Avaya with 14 percent, 3Com with 11 percent and Nortel with 9 percent, according to Gartner's research. Cisco reported five separate security bugs in CallManager, Functional testing voipthe call- processing component of the Cisco IP telephony system. The most serious is in the aupair.exe service, which could info testing voip allow a remote attacker to cause VoIP Main Page a buffer overflow and execute malicious code. Aupair.exe can't be disabled for normal CallManager use, Cisco said. CallManager is vulnerable in its default configuration, and an attack could be carried out without the need for prior authentication, ISS said. An attacker may be able to redirect calls or Performance testing voipperform eavesdropping as a result functional VoIP Main Page testing voip of this compromise. Successful exploitation of this vulnerability could be used to gain unauthorized access to networks and machines with Cisco VOIP products, the security firm said in an advisory. Cisco has released patches for the affected versions of CallManager, VoIP Main Page including 3.3 Conformance testing voipand earlier, 4.0 and 4.1. Its advisory and patching instructions are on Cisco's Web site.
