At Internet Security Systems Inc. (ISS) they have discovered fatal flaws in web conferencing products. The one from WebEx included. It is the first flaw that they have shared publicly. They are closely working with vendors so that they could patch it already.
The WebEx flaw
This flaw that was discovered could be used to run unauthorized software on a computer. It has something to do with the ActiveX component it uses. As such, it is imperative that those who use it update the software as soon as possible. If you are one who does not have automatic updates on, you could download the patch from the WebEx site itself.
For those who use VoIP regularly and are concerned with their data, flaws in the software used must be checked and patched immediately, if there are available ones. The possibility of an attacker to run unauthorized software on your own computer is terrible. It could different things which might compromise the integrity of the data on your computer.
The idea that there are security flaws which are yet undiscovered in VoIP is something that makes some companies reluctant to adopting the technology. That is why some companies are still waiting for it to become more secure and stable. The convenience of communicating via such software would be nice. The thing is that it might be more costly to do damage control, in case the time when it is necessary. Hopefully, other flaws will surface and be patched immediately.
