CVE-2022-20805

13
FAUCET Score

CVE-2022-20805 is a medium-severity vulnerability affecting Cisco Umbrella Secure Web Gateway (SWG) that allows an authenticated, adjacent attacker to bypass SSL decryption and content filtering policies. This bypass occurs due to a flaw in how the SWG uses the TLS Server Name Indication (SNI) extension, enabling an attacker to send crafted requests to an unknown or controlled URL. A successful exploit could lead to malicious content being downloaded to a protected host, though there are workarounds available. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
