CVE-2017-20041Public exploitNetwork attack vector

URL spoofing via crafted HTML title

Published Jun 13, 2022 · Updated Apr 15, 2025

URL spoofing in UCWeb UC Browser 11.2.5.932 allows remote attackers to display a false address after a victim opens crafted HTML. The Android HTML handler renders text from a page's title element as the browser's displayed URL instead of preserving the loaded origin. The victim must open attacker-controlled content, after which the false address can support phishing without changing the underlying page origin.
