34
FAUCET Score

CVE-2017-2371 describes a vulnerability in Apple iOS before version 10.2.1, specifically within the WebKit component, which allows remote attackers to bypass popup blockers via a crafted website. This medium-severity vulnerability (CVSS 6.5) requires user interaction (UI:R) and could lead to high integrity impact (I:H) through unwanted popups, though it does not affect confidentiality or availability. While not actively exploited in the wild (no KEV listing), an ExploitDB entry (EDB-41451) exists demonstrating a popup blocker bypass, but there is no evidence of broader community discussion or media coverage.
