Description

A vulnerability in the web-based interface of Cisco Webex Teams could allow an authenticated, remote attacker to conduct cross-site scripting attacks.
The vulnerability is due to improper validation of usernames. An attacker could exploit this vulnerability by creating an account that contains malicious HTML or script content and joining a space using the malicious account name. A successful exploit could allow the attacker to conduct cross-site scripting attacks and potentially gain access to sensitive browser-based information.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
