Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-56435 is a cross-process screen stack vulnerability in the UIExtension module, as identified in Huawei's security bulletin. Published on January 8, 2025, it carries a CVSS v3.1 base score of 6.2 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating medium severity with high impact on confidentiality but no impact on integrity or availability. The vulnerability is linked to CWE-1021 (Improper Restriction of Rendered UI Layers or Frames) and insufficient NVD CWE information.
A local attacker with no privileges required can exploit this vulnerability due to its low attack complexity and lack of need for user interaction. Successful exploitation allows unauthorized access to confidential service data across processes, potentially exposing sensitive information without altering or disrupting system operations.
Huawei's consumer support bulletin at https://consumer.huawei.com/en/support/bulletin/2025/1/ provides details on affected devices and recommended patches or mitigations to address the issue. Security practitioners should review the advisory for version-specific updates and apply them promptly to vulnerable UIExtension implementations.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require implementing frame-ancestors / X-Frame-Options controls that prevent this weakness.

Security testing can detect missing frame protections, but does not itself implement the control.
Web filtering can block or sandbox untrusted frames, but does not enforce application-level frame-busting or CSP.
Application security requirements can mandate frame-ancestors / X-Frame-Options, directly addressing UI redressing risks.
Secure architecture principles include isolation of UI layers and proper use of browser security controls.
Secure coding practices directly require implementation of frame-busting headers or CSP frame-ancestors directives.
