- Severity: CVSS 6.1 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- Known exploited (CISA KEV): no
- Fixed in: 10.2.9, 9.2.20, 8.2.27, 7.8.2.31, 11.1.3
- Published: 2022-04-20 · Updated: 2024-08-02

## Affected

- McAfee,LLC Secure Web Gateway: from 10.X, fixed in 10.2.9; from 9.x, fixed in 9.2.20; from 8.x, fixed in 8.2.27; from 7.x, fixed in 7.8.2.31; from Controlled 11.x, fixed in 11.1.3

## 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.

## What to do

- Check your stack: if you ship or depend on McAfee,LLC Secure Web Gateway, upgrade to a fixed version (10.2.9, 9.2.20, 8.2.27, 7.8.2.31, 11.1.3) per the references below.
