CVE-2024-38208 is a cross-site scripting (XSS) vulnerability classified under CWE-79, affecting Microsoft Edge for Android version 1.0.0. This vulnerability arises due to improper neutralization of input during web page generation, allowing an attacker to inject malicious scripts into web content viewed by users. When exploited, this can lead to spoofing attacks where the attacker can manipulate the appearance or behavior of web pages to deceive users. The vulnerability has a CVSS 3.1 base score of 6.1, indicating a medium severity level. The attack vector is network-based (AV:N), requiring no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact affects confidentiality and integrity (C:L/I:L) but not availability (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in June 2024 and published in August 2024. Given that Microsoft Edge for Android is a widely used mobile browser, this vulnerability could be leveraged by attackers to execute malicious scripts when users visit crafted or compromised websites, potentially leading to theft of sensitive information, session hijacking, or misleading users via spoofed content. The requirement for user interaction (such as clicking a link) limits automated exploitation but does not eliminate risk, especially in phishing scenarios. The changed scope indicates that the impact could extend beyond the browser sandbox, potentially affecting other components or data accessible through the browser. Overall, this vulnerability represents a significant risk for users of Microsoft Edge on Android devices, particularly in environments where sensitive data is accessed via mobile browsers.

For European organizations, the impact of CVE-2024-38208 can be considerable, especially those relying on Microsoft Edge for Android for accessing corporate resources, web applications, or sensitive information. Successful exploitation could lead to unauthorized disclosure of confidential data, session hijacking, or manipulation of web content to deceive users into divulging credentials or executing harmful actions. This is particularly critical for sectors such as finance, healthcare, government, and critical infrastructure where mobile access is common and data sensitivity is high. The medium severity score reflects moderate risk, but the changed scope and potential for spoofing increase the threat level in real-world scenarios. Organizations with mobile-first strategies or remote workforces using Android devices are at heightened risk. Additionally, the lack of a patch at the time of publication means organizations must rely on interim mitigations. The vulnerability could also be exploited in targeted phishing campaigns leveraging the spoofing capability to increase success rates. Given the widespread use of Microsoft Edge on Android in Europe, the threat could affect a broad user base, potentially leading to data breaches or reputational damage if exploited.

1. Immediate mitigation should focus on user awareness and training to recognize phishing attempts and suspicious links, reducing the likelihood of user interaction with malicious content. 2. Organizations should enforce mobile device management (MDM) policies that restrict installation of untrusted applications and enforce browser usage policies. 3. Where possible, restrict or monitor the use of Microsoft Edge for Android on corporate devices until a patch is available. 4. Employ network-level protections such as web filtering and intrusion detection systems to block access to known malicious URLs or domains that could exploit this vulnerability. 5. Encourage users to disable JavaScript or use browser extensions that limit script execution on untrusted sites, though this may impact usability. 6. Monitor security advisories from Microsoft closely and apply patches immediately once released. 7. Implement multi-factor authentication (MFA) on all sensitive applications accessed via mobile browsers to reduce the impact of credential theft. 8. Use endpoint detection and response (EDR) solutions capable of detecting anomalous browser behavior indicative of exploitation attempts. These steps go beyond generic advice by focusing on organizational controls, user behavior, and layered defenses specific to mobile browser vulnerabilities.
