A vulnerability in client join services of Cisco Webex Meetings could allow an unauthenticated, remote attacker to manipulate cached HTTP responses within the meeting join service.
Does this matter?
Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.
Description
A vulnerability in client join services of Cisco Webex Meetings could allow an unauthenticated, remote attacker to manipulate cached HTTP responses within the meeting join service. This vulnerability is due to improper handling of malicious HTTP requests to the affected service. An attacker could exploit this vulnerability by manipulating stored HTTP responses within the service, also known as HTTP cache poisoning. A successful exploit could allow the attacker to cause the Webex Meetings service to return incorrect HTTP responses to clients.
