CVE-2022-20738

A vulnerability in the Cisco Umbrella Secure Web Gateway service could allow an unauthenticated, remote attacker to bypass the file inspection feature. This vulnerability is due to insufficient restrictions in the file inspection feature. An attacker could exploit this vulnerability by downloading a crafted payload through specific methods. A successful exploit could allow the attacker to bypass file inspection protections and download a malicious payload.
