## What is CVE-2022-1254?

CVE-2022-1254 is a medium-severity vulnerability in McAfee,LLC Secure Web Gateway, published on 20 Apr 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

A URL redirection vulnerability in Skyhigh SWG in main releases 10.x prior to 10.2.9, 9.x prior to 9.2.20, 8.x prior to 8.2.27, and 7.x prior to 7.8.2.31, and controlled release 11.x prior to 11.1.3 allows a remote attacker to redirect a user to a malicious website controlled by the attacker. This is possible because SWG incorrectly creates a HTTP redirect response when a user clicks a carefully constructed URL. Following the redirect response, the new request is still filtered by the SWG policy.

Weakness: CWE-601 (URL Redirection to Untrusted Site)
