What is CVE-2024-38112?

CVE-2024-38112 is a spoofing vulnerability found in the MSHTML platform of Microsoft's Windows operating system. The MSHTML platform is essential for rendering HTML content, playing a crucial role in web browsing and various applications that display web-based content. This vulnerability allows attackers to potentially manipulate the way in which HTML content is interpreted, leading to misleading representations of the information presented to users. If exploited, organizations could face severe security risks, including data theft or the execution of malicious code under the guise of trusted sources.

Technical Details

The vulnerability exists within the MSHTML platform, which is integrated into several Microsoft applications. It occurs due to improper handling of the HTML content, allowing for the possibility of spoofed content being displayed to the user. Attackers could exploit this flaw by crafting special HTML content that misrepresents data or misleads users into believing they are interacting with legitimate entities. The complexity of the vulnerability necessitates an understanding of how web content is rendered and processed by the MSHTML platform.

Impact of the Vulnerability

  1. User Deception: Exploitation of this vulnerability may lead users to believe they are visiting a legitimate site or using a trustworthy application, resulting in unauthorized information disclosure or the submission of sensitive information.

  2. Increased Attack Surface: Organizations could be exposing themselves to a wider range of attack vectors as attackers leverage this vulnerability to craft malicious content, potentially spreading malware or initiating phishing campaigns.

  3. Reputational Damage: If an organization falls victim to an exploit utilizing this vulnerability, it could suffer significant reputational harm, eroding customer trust and resulting in long-term financial impacts due to loss of clientele and remediation costs.
