CVE-2025-49755 is a vulnerability classified under CWE-451, which pertains to user interface misrepresentation of critical information. This issue affects Microsoft Edge for Android version 1.0.0 and allows an unauthorized attacker to perform spoofing attacks over a network. The vulnerability arises because the browser can be manipulated to display falsified UI elements that misrepresent critical information to the user, potentially leading to deception. The attack vector is network-based (AV:N), requiring no privileges (PR:N) but does require user interaction (UI:R) to succeed. The scope is unchanged (S:U), and the impact is limited to integrity (I:L) with no impact on confidentiality or availability. The CVSS score of 4.3 reflects a medium severity, indicating moderate risk. No patches or exploits are currently known, but the vulnerability could be exploited in phishing or social engineering campaigns to trick users into taking harmful actions or disclosing sensitive information. The lack of authentication requirements and ease of exploitation over a network make it a concern for mobile users, especially in environments where Microsoft Edge is widely deployed on Android devices.

For European organizations, this vulnerability poses a risk primarily to the integrity of user interactions and trust in web content viewed via Microsoft Edge on Android devices. Attackers could exploit this flaw to conduct phishing attacks or deliver misleading information, potentially leading to credential theft, unauthorized transactions, or installation of malicious software. Sectors such as finance, government, and critical infrastructure, which rely heavily on secure communications and user trust, could be particularly impacted. The vulnerability does not directly compromise confidentiality or availability but undermines user confidence and can facilitate further attacks. Given the widespread use of Android devices and Microsoft Edge in Europe, the threat could affect a significant number of users, especially mobile workforce and remote employees. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks.

Organizations should implement targeted mitigation strategies including: 1) Educating users about the risks of UI spoofing and encouraging vigilance when interacting with unexpected or suspicious browser prompts or content. 2) Monitoring network traffic for anomalies that could indicate spoofing attempts or man-in-the-middle activities. 3) Deploying mobile device management (MDM) solutions to enforce security policies and restrict installation of untrusted applications. 4) Encouraging users to update Microsoft Edge for Android promptly once a patch is released by Microsoft. 5) Utilizing browser security features such as HTTPS enforcement and certificate pinning to reduce the risk of network-based spoofing. 6) Conducting regular security awareness training focused on phishing and social engineering tactics that could leverage this vulnerability. 7) Collaborating with IT teams to monitor for unusual user behavior or access patterns that may indicate exploitation attempts.
