vulnerability analysis and mitigation

A UI spoofing vulnerability (CVE-2025-1917) was discovered in Google Chrome's Browser UI on Android versions prior to 134.0.6998.35. The vulnerability stems from an inappropriate implementation that could allow remote attackers to perform UI spoofing attacks through specially crafted HTML pages. The issue was initially reported by security researcher Khalil Zhani on March 14, 2024, and was assigned a Medium severity rating by the Chromium security team (Chrome Release, NVD).

The vulnerability has been classified under CWE-1021 (Improper Restriction of Rendered UI Layers or Frames). According to the CVSS 3.1 scoring system, it received a base score of 4.3 (Medium) with the following vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N. This indicates that the vulnerability is network-accessible, requires low attack complexity, needs no privileges, requires user interaction, has a limited impact on integrity, and does not affect confidentiality or availability (NVD).

The vulnerability allows attackers to perform UI spoofing attacks, which could potentially mislead users through manipulated interface elements. The impact is considered limited as it requires user interaction and only affects the integrity aspect of the system, with no direct impact on confidentiality or availability (NVD).
