CVE-2022-28869Network attack vector

Phishing via truncated address-bar URLs

Published Apr 15, 2022 · Updated Aug 3, 2024

URL spoofing in F-Secure Mobile Security 18.6 and earlier allows remote attackers to present deceptive sites through its Android browser. The browser omits parts of a crafted page URL, including the port number, from the address bar, so its displayed origin does not fully identify the loaded site. A user must open the malicious website, and the demonstrated consequence is phishing through a misleading address display.
