Cisco Intelligent Proximity SSL Certificate Validation Vulnerability

Details

The vulnerability is due to a lack of validation of the SSL server certificate received when establishing a connection to a Cisco Webex video device or a Cisco collaboration endpoint. An attacker could exploit this vulnerability by using man in the middle (MITM) techniques to intercept the traffic between the affected client and an endpoint, and then using a forged certificate to impersonate the endpoint. Depending on the configuration of the endpoint, an exploit could allow the attacker to view presentation content shared on it, modify any content being presented by the victim, or have access to call controls.

Vulnerable Systems:

  • Cisco Intelligent Proximity application
  • Cisco Jabber
  • Cisco Webex Meetings
  • Cisco Webex Teams
  • Cisco Meeting App
