A vulnerability in the loading mechanism of specific DLLs in the Cisco Webex Teams client for Windows could allow an authenticated, local attacker to load a malicious library.

A successful exploit could allow the attacker to execute arbitrary code on the targeted system with the privileges of another user’s account.
