{"id":"CVE-2021-40835","state":"PUBLISHED","title":"URL Address Bar Spoofing in F-Secure SAFE Browser for iOS","description":"An URL Address bar spoofing vulnerability was discovered in Safe Browser for iOS. When user clicks on a specially crafted a malicious URL, if user does not carefully pay attention to url, user may be tricked to think content may be coming from a valid domain, while it comes from another. This is performed by using a very long username part of the url so that user cannot see the domain name. A remote attacker can leverage this to perform url address bar spoofing attack. The fix is, browser no longer shows the user name part in address bar.","publishedAt":"2021-12-16T10:58:55.000Z","updatedAt":"2024-08-04T02:51:07.421Z","severity":{"score":4.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","source":"F-SecureUS"},"assigner":"F-SecureUS","products":["F-Secure F-Secure Mobile Security"],"affected":[{"vendor":"F-Secure","product":"F-Secure Mobile Security","versions":[{"version":"18.3","status":"affected","lessThan":"18.5","versionType":"custom"}],"platforms":["iOS"]}],"references":["https://www.f-secure.com/en/business/programs/vulnerability-reward-program/hall-of-fame","https://www.f-secure.com/en/business/support-and-downloads/security-advisories"],"weaknesses":[],"ingestedAt":"2026-10-29T19:48:58.929Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/40xxx/CVE-2021-40835.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-40835","state":"PUBLISHED","datePublished":"2021-12-16T10:58:55.000Z","dateUpdated":"2024-08-04T02:51:07.421Z","assignerShortName":"F-SecureUS","assignerOrgId":"126858f1-1b65-4b74-81ca-7034f7f7723f","dateReserved":"2021-09-09T00:00:00.000Z"},"containers":{"cna":{"title":"URL Address Bar Spoofing in F-Secure SAFE Browser for iOS","descriptions":[{"lang":"en","value":"An URL Address bar spoofing vulnerability was discovered in Safe Browser for iOS.
