Apple iOS < 12.5.2 XSS (HT212257)

medium Nessus Plugin ID 148262


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


The version of Apple iOS running on the mobile device is prior to 12.5.2. 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.


Upgrade to Apple iOS version 12.5.2 or later
