CVE-2022-20863: Cisco Security Advisory: Cisco Webex Meetings App Character Interface Manipulation Vulnerability
A vulnerability in the messaging interface of Cisco Webex App, formerly Webex Teams, could allow an unauthenticated, remote attacker to manipulate links or other content within the messaging interface. This vulnerability exists because the affected software does not properly handle character rendering. An attacker could exploit this vulnerability by sending messages within the application interface. A successful exploit could allow the attacker to modify the display of links or other content within the interface, potentially allowing the attacker to conduct phishing or spoofing attacks.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
