How to Hack Cisco Webex Meetings for Fun with Tricks and Exploits
It comes with a flaw that you can access the complete scheme of the company. Karl Fosaaen published research on federated services and skype for companies. An attacker vector located address books of other companies and sent messages from skype for business, including all the features like seeing when someone is online; similar has been discovered in WebEx.
It allows users to use the domain “companyname.webex.com” to host public meeting rooms.
The best feature is enabling private meeting rooms. Every employee receives a personal meetings room so meetings can be organized through this. Employees can share links with the ones they communicate.
A commonly used link is “companyname.webex.com/meet/userid”. User ID is the user name or mail address of a domain. As you are known about the name of the scheme of personal rooms of the company you can enter into the personal office of anyone as user wants from any place around the globe.
As you go to the link in the personal meeting room, the following page is displayed:
As details are entered that user desires, you are directly redirected to a secret room. If the person is not in the place currently, then the following is presented:
As you click on notify, email is sent to the owner of the room. The mail is generated and sent from messenger[@]webex.com. This is just an example and can be anything from within the company.
This will allow you to:
- Enumerate valid user names directly.
- Access to any user within the company.
How to know if a meeting is affected?
- You need to verify the link URL of the private room by entering the WebEx configuration.
- Access that link from a system outside your network; it is vulnerable if you can enter the room.
What can you do to avoid this?
- Change URL of the private room, depending on settings.
- Ask the IT department to change room ID.
A quick subdomain enumeration on WebEx.com has discovered many domains for organizations that use it in this way. A similar flaw is available in Skype, where it allows you to find the IP address of the person who is on the call.
