Overview
A medium severity vulnerability, identified as CVE-2025-62223, has been discovered in Microsoft Edge for iOS. This vulnerability allows an unauthorized attacker to perform spoofing over a network due to user interface (UI) misrepresentation of critical information. This article provides a detailed analysis of the vulnerability, its potential impact, and necessary mitigation steps.
Technical Details
CVE-2025-62223 stems from how Microsoft Edge for iOS displays information within its user interface. The vulnerability involves the misrepresentation of critical information, which can be exploited by an attacker to present misleading data to the user. This misrepresentation can trick the user into believing they are interacting with a legitimate service or website when, in reality, they are connecting to a malicious entity controlled by the attacker. The specific nature of the UI misrepresentation isn’t fully detailed in the initial disclosure, but it likely involves elements like the address bar, security indicators, or other visual cues that users rely on to verify authenticity.
An attacker leveraging this vulnerability would need to be positioned to intercept network traffic between the user’s device and the intended server. This could be achieved through techniques like man-in-the-middle (MITM) attacks on unsecured Wi-Fi networks or by compromising a router or DNS server.
CVSS Analysis
The vulnerability has been assigned a CVSS score of 4.3, indicating a medium severity level. The CVSS vector reflects the following characteristics:
- Attack Vector (AV): Network (N)
- Attack Complexity (AC): High (H)
- Privileges Required (PR): None (N)
- User Interaction (UI): Required (R)
- Scope (S): Unchanged (U)
- Confidentiality Impact (C): None (N)
- Integrity Impact (I): Low (L)
- Availability Impact (A): None (N)
The high attack complexity suggests that exploiting this vulnerability requires specific conditions and a degree of technical skill. User interaction is required, meaning the attacker needs to trick the user into performing an action, such as clicking on a link or ignoring a security warning. The low integrity impact indicates that the attacker can modify some data, but the overall impact is limited.
Possible Impact
Successful exploitation of CVE-2025-62223 could lead to various forms of spoofing attacks, including:
- Phishing: The attacker could redirect the user to a fake login page to steal credentials.
- Malware Distribution: The attacker could trick the user into downloading and installing malicious software.
- Information Disclosure: The attacker could present misleading information to the user, potentially causing them to reveal sensitive data.
While the CVSS score is medium, the potential impact can be significant depending on the attacker’s objectives and the user’s susceptibility to social engineering.
Mitigation and Patch Steps
The primary mitigation step is to update Microsoft Edge for iOS to the latest version as soon as the patch is available. Microsoft typically releases security updates through the App Store. Follow these steps:
- Open the App Store on your iOS device.
- Tap your profile icon at the top of the screen.
- Scroll down to see pending updates and release notes.
- If an update for Microsoft Edge is available, tap “Update.”
In addition to patching, users can take the following precautions:
- Be wary of suspicious links and websites. Always double-check the URL before entering sensitive information.
- Use a strong and unique password for each online account.
- Enable two-factor authentication (2FA) wherever possible.
- Use a VPN when connecting to public Wi-Fi networks.
- Regularly review app permissions on your iOS device.
