A vulnerability in Cisco Webex Teams, formerly Cisco Spark, could allow an authenticated, remote attacker to view and modify data for an organization other than their own organization. The vulnerability exists because the affected software performs insufficient checks for associations between user accounts and organization accounts. An attacker who has administrator or compliance officer privileges for one organization account could exploit this vulnerability by using those privileges to view and modify data for another organization account. No customer data was impacted by this vulnerability.

A vulnerability in Cisco Webex Teams (for Windows and macOS) could allow an unauthenticated, remote attacker to execute arbitrary code on the user's device, possibly with elevated privileges. The vulnerability occurs because Cisco Webex Teams does not properly sanitize input. An attacker could exploit the vulnerability by sending a user a malicious link and persuading the user to follow the link. A successful exploit could allow the attacker to execute arbitrary code on the user's system. Cisco Bug IDs: CSCvh66250.
