CVE-2022-38163 is a vulnerability identified in the F-Secure SAFE Browser for Android and iOS, specifically affecting versions 19.0 and below. The issue is classified as a Drag and Drop spoof vulnerability, where a user-initiated drag and drop operation on the browser's address bar can lead to spoofing of the address bar content. This means that an attacker could manipulate the displayed URL in the address bar during or after a drag and drop action, potentially misleading users about the actual website they are visiting. The vulnerability falls under CWE-451, which relates to improper representation of user interface elements, leading to spoofing attacks. The CVSS v3.1 base score is 3.5, indicating a low severity level. The vector details are AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N, meaning the attack can be executed remotely over the network with low attack complexity, requires low privileges, and user interaction is necessary. The impact is limited to integrity, with no confidentiality or availability impact. No known exploits in the wild have been reported, and no patches or vendor-specific mitigations are currently listed. The vulnerability is specific to the F-Secure SAFE Browser mobile application, which is a security-focused browser designed to provide safe browsing on mobile devices.

For European organizations, the primary risk posed by this vulnerability is the potential for phishing or social engineering attacks that leverage the spoofed address bar to deceive users into believing they are on legitimate websites. This could lead to credential theft, unauthorized transactions, or installation of malware if users are tricked into interacting with malicious sites. However, the impact is somewhat mitigated by the requirement for user interaction (drag and drop) and the need for low privileges, which limits the ease of exploitation. Since the vulnerability affects mobile browsers, organizations with a significant mobile workforce or those relying on F-Secure SAFE Browser for secure mobile browsing could see increased risk. The integrity of the browsing experience is compromised, which can undermine user trust and potentially lead to targeted attacks against employees or customers. Given the low CVSS score and absence of known exploits, the immediate risk is low, but the vulnerability could be leveraged in targeted phishing campaigns if combined with other attack vectors.

1. Immediate mitigation involves educating users about the risks of drag and drop operations within the F-Secure SAFE Browser, particularly on the address bar, and advising caution when interacting with URLs during such operations. 2. Organizations should monitor for updates from F-Secure and apply patches or browser updates as soon as they become available to address this vulnerability. 3. Implement mobile device management (MDM) policies to restrict or control the use of vulnerable browser versions, including enforcing browser updates or restricting installation of unapproved browsers. 4. Employ endpoint protection solutions that can detect and block phishing attempts and malicious URLs, reducing the risk even if address bar spoofing occurs. 5. Encourage multi-factor authentication (MFA) for critical services to mitigate the impact of credential theft resulting from phishing. 6. Conduct targeted phishing awareness training that includes scenarios involving browser spoofing and UI manipulation to improve user detection capabilities. 7. Consider deploying network-level protections such as DNS filtering and secure web gateways to block access to known malicious domains that could exploit this vulnerability.
