CVE-2025-21262 identifies a medium-severity vulnerability in Microsoft Edge (Chromium-based). This vulnerability allows unauthorized attackers to perform spoofing over a network due to User Interface (UI) misrepresentation of critical information. The potential for abuse emphasizes the importance of timely updates to protect users and organizations.
The CVSS score for this vulnerability is 5.4, indicating a medium severity level. This score reflects the potential risk to organizations, particularly in scenarios where user interaction is required for exploitation. As attackers may leverage this vulnerability for phishing attacks or other malicious activities, it is crucial for organizations to understand the implications.
Organizations should prioritize patching immediately. The publication date of this vulnerability was January 24, 2025, and it has been classified under CWE-451, indicating an issue related to improper UI handling that could lead to misrepresentation.
The urgency for defenders to act is underscored by the low attack complexity and the fact that no privileged access is required to exploit this vulnerability. Timely remediation is essential to mitigate the risks associated with potential spoofing attacks.
Vulnerability Details
The official description of CVE-2025-21262 states that the vulnerability results from a misrepresentation in the User Interface (UI) of Microsoft Edge (Chromium-based). This misrepresentation could allow unauthorized attackers to perform spoofing attacks over a network.
The CVSS score of 5.4 indicates a medium severity risk, with the following characteristics:
Attribute | Value |
|---|---|
Attack Vector | Network |
Attack Complexity | Low |
Privileges Required | None |
User Interaction | Required |
Confidentiality Impact | Low |
Integrity Impact | Low |
Availability Impact | None |
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access and manipulation of critical information. The ability to spoof critical information can lead to significant reputational damage and financial loss, particularly if users are misled into providing sensitive information.
Given the CVSS score of 5.4, organizations should address this vulnerability in their priority patch cycle. The urgency for remediation is heightened by the low attack complexity and the requirement for user interaction, which may make it more feasible for attackers to exploit unaware users.
