CVE-2025-47967 is a vulnerability identified in the Chromium-based Microsoft Edge browser for Android, specifically version 1.0.0.0. The issue is classified under CWE-357, which pertains to insufficient user interface warnings for dangerous operations. This vulnerability allows an unauthorized attacker to perform spoofing attacks over a network by exploiting the lack of adequate UI warnings that would normally alert users to potentially harmful actions. Spoofing in this context means that an attacker can deceive the user into believing they are interacting with a legitimate interface or operation when, in fact, malicious activity is occurring. The vulnerability does not require any privileges or authentication (PR:N), but it does require user interaction (UI:R), such as clicking or engaging with the browser interface. The attack vector is network-based (AV:N), meaning the attacker can exploit this remotely over a network connection. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component, potentially impacting other parts of the system or user data. The impact on confidentiality is none (C:N), but there is a low impact on integrity (I:L) and no impact on availability (A:N). The exploitability is rated as unproven (E:U), and the remediation level is official (RL:O) with confirmed report confidence (RC:C). No known exploits are currently in the wild, and no patches have been linked yet. Overall, this vulnerability represents a medium-severity risk due to its potential to mislead users into unsafe operations without proper UI warnings, which could lead to integrity compromises such as unauthorized changes or data manipulation within the browser context.

For European organizations, this vulnerability poses a moderate risk primarily in environments where Microsoft Edge on Android is widely used for accessing corporate resources or sensitive information. The spoofing capability could be leveraged by attackers to trick users into performing unintended actions, such as submitting credentials to phishing sites or approving malicious transactions, thereby compromising data integrity. Although the confidentiality impact is rated as none, the integrity impact could lead to unauthorized modifications of data or settings, potentially undermining trust in web applications and internal systems accessed via the browser. The network-based attack vector means that attackers could exploit this vulnerability remotely, increasing the risk in public or unsecured Wi-Fi environments common in business travel or remote work scenarios. Given the widespread use of Android devices and Microsoft Edge in Europe, especially in sectors like finance, government, and healthcare, the vulnerability could facilitate targeted social engineering campaigns or man-in-the-middle attacks that exploit the insufficient UI warnings to deceive users. However, the lack of known exploits and the medium CVSS score suggest that immediate widespread impact is limited but should not be underestimated in high-value target environments.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Deploy the latest updates and patches from Microsoft as soon as they become available, even though no patches are currently linked, monitoring official Microsoft security advisories closely. 2) Implement strict network security controls such as enforcing the use of VPNs and secure Wi-Fi connections to reduce exposure to network-based attacks. 3) Educate users about the risks of spoofing and the importance of verifying UI prompts, especially when interacting with sensitive operations in the browser. 4) Employ mobile device management (MDM) solutions to enforce browser configuration policies that limit risky behaviors and restrict installation of untrusted extensions or apps. 5) Use endpoint detection and response (EDR) tools that can monitor for unusual browser behaviors indicative of spoofing or manipulation attempts. 6) Encourage the use of multi-factor authentication (MFA) on critical services accessed via the browser to reduce the impact of potential spoofing attacks. 7) Conduct regular security awareness training focused on recognizing suspicious UI elements and phishing attempts on mobile devices. These measures collectively reduce the likelihood of successful exploitation and limit the potential damage from this vulnerability.
