Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.90%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A vulnerability in the login authorization components of Cisco Webex Meetings could allow an authenticated, remote attacker to inject arbitrary Java code. This vulnerability is due to improper deserialization of Java code within login requests. An attacker could exploit this vulnerability by sending malicious login requests to the Cisco Webex Meetings service. A successful exploit could allow the attacker to inject arbitrary Java code and take arbitrary actions within the Cisco Webex Meetings application.
