CVE-2025-0440 is a medium-severity vulnerability found in Google Chrome, specifically impacting versions prior to 132.0.6834.83. This vulnerability allows remote attackers to exploit inappropriate implementation in the Fullscreen feature, enabling them to perform UI spoofing via a crafted HTML page. The risk to organizations includes potential unauthorized access to sensitive data through deceptive user interfaces.
The CVSS score of 6.5 indicates a moderate level of risk, with an attack vector classified as network. This implies that attackers can exploit this vulnerability remotely, requiring low complexity and no privileges, but necessitating user interaction. Organizations should address this vulnerability promptly to mitigate potential risks associated with UI spoofing.
The urgency for defenders is high, as the vulnerability can lead to significant impacts on data integrity, despite having no confidentiality or availability impacts. Organizations should prioritize patching immediately.
Currently, there are no known exploits or public proofs of concept available for this vulnerability, which provides a small window of opportunity for organizations to mitigate the risk by updating their systems.
Vulnerability Details
This vulnerability allows a remote attacker to perform UI spoofing via a crafted HTML page in Google Chrome on Windows prior to version 132.0.6834.83. The CVSS score of 6.5 reflects a medium severity level, indicating moderate risk in deployment scenarios.
The CWE classification for this vulnerability is CWE-290, indicating that it involves authentication issues. The publication date of this vulnerability is January 15, 2025, and it is categorized as analyzed.
Technical Analysis
The root cause of this vulnerability lies in the inappropriate implementation of the Fullscreen feature, which can be exploited by attackers to create a spoofed user interface that misleads users. The attack vector is network-based, which means that attackers can initiate the attack remotely.
The attack complexity is low, allowing attackers to exploit the vulnerability without significant obstacles. No privileges are required for exploitation, but user interaction is necessary, as the attacker needs the victim to open the malicious HTML page.
While the vulnerability does not impact confidentiality or availability, it does pose a high risk to integrity, as attackers may manipulate the UI to perform unauthorized actions without the user's knowledge.
Risk & Impact Analysis
Organizations utilizing Google Chrome are at risk of being targeted through this vulnerability. The ability for attackers to spoof the UI can lead to users inadvertently providing sensitive information or performing actions that compromise their security.
The blast radius of this vulnerability extends to any user of the affected versions of Chrome, potentially impacting wide swathes of users if not addressed. Given that the vulnerability is categorized as medium severity, organizations should address it in their priority patch cycle.
The urgency is reflected in the CVSS score and the potential for exploitation, underscoring the necessity for immediate remediations.
