Apple iOS < 14.4.2 XSS (HT212256)

medium Nessus Plugin ID 148263

Language:

Synopsis

The version of Apple iOS running on the mobile device is missing a vendor-supplied patch.

Description

The version of Apple iOS running on the mobile device is prior to 14.4.2. It is, therefore, affected by a cross-site scripting (XSS) vulnerability in its WebKit component due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

Solution

Upgrade to Apple iOS version 14.4.2 or later
