Title

Cisco Webex Meetings Certificate Validation Vulnerability

Summary

A vulnerability in the integration of single sign-on (SSO) with Control Hub in Cisco Webex Services could have allowed an unauthenticated, remote attacker to impersonate any user within the service. This vulnerability existed because of improper certificate validation. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by connecting to a service endpoint and supplying a crafted token. A successful exploit could have allowed the attacker to gain unauthorized access to legitimate Cisco Webex services.

Summary

Cisco Webex Services Certificate Validation Vulnerability

Notes

Summary: A vulnerability in the integration of single sign-on (SSO) with Control Hub in Cisco Webex Services could have allowed an unauthenticated, remote attacker to impersonate any user within the service. This vulnerability existed because of improper certificate validation. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by connecting to a service endpoint and supplying a crafted token. A successful exploit could have allowed the attacker to gain unauthorized access to legitimate Cisco Webex services. Cisco has addressed this vulnerability in the Cisco Webex service. However, customer action is necessary for affected organizations that are using SSO integration. There are no workarounds that address this vulnerability. To avoid service interruption, customers who are using SSO should upload a new identity provider (IdP) SAML certificate to Control Hub. For more information, see Manage single sign-on integration in Control Hub ["https://help.webex.com/en-us/article/nstvmyo/Manage-single-sign-on-integration-in-Control-Hub#task_394598AFBCD3D73A488E6DBB99AD3214"].

Vulnerable Products: This vulnerability affected Cisco Webex Services, which are cloud-based, when they were configured to use SSO integration with Control Hub.

Products Confirmed Not Vulnerable: Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to have been affected by this vulnerability.

Workarounds: There are no workarounds that address this vulnerability.

Fixed Software: Cisco has addressed this vulnerability in Cisco Webex Services, which are cloud based. To avoid service interruption, customers who are using SSO should upload a new identity provider (IdP) SAML certificate to Control Hub. For more information, see Manage single sign-on integration in Control Hub ["https://help.webex.com/en-us/article/nstvmyo/Manage-single-sign-on-integration-in-Control-Hub#task_394598AFBCD3D73A488E6DBB99AD3214"]. Customers who need additional information are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.

Vulnerability Policy: To learn about Cisco security vulnerability disclosure policies and publications, see the Security Vulnerability Policy ["http://www.cisco.com/web/about/security/psirt/security_vulnerability_policy.html"]. This document also contains instructions for obtaining fixed software and receiving security vulnerability information from Cisco.

Exploitation and Public Announcements: The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.

Source: This vulnerability was found during internal security testing.
