CVE-2024-21388 is an elevation of privilege vulnerability found in Microsoft Edge, a web browser built on the Chromium platform. This vulnerability allows attackers to gain higher privileges than intended within the affected software, which can lead to unauthorized access to system resources and critical data. Organizations utilizing Microsoft Edge may face significant security risks, as an exploited vulnerability could enable malicious actors to manipulate web sessions, extract sensitive information, or perform unauthorized actions on behalf of legitimate users.

Technical Details

CVE-2024-21388 arises from flaws in how Microsoft Edge handles specific inputs. By leveraging this vulnerability, attackers can execute arbitrary code in the context of a privileged process. The elevation of privilege nature of this vulnerability means that it does not require user interaction, making it particularly dangerous. To exploit this flaw, an attacker would need to convince a user to open a specially crafted web page or load malicious content that triggers the vulnerability.

Impact of the Vulnerability

1. Unauthorized Access to Sensitive Data: Successful exploitation of this vulnerability could lead to unauthorized access to sensitive information within the user's browsing session, allowing attackers to view or manipulate private data.

2. System Compromise: Once elevated privileges are gained, attackers may install malicious payloads or gain further access to the operating system, potentially leading to a full system compromise.

3. Widespread Malware Deployment: The exploitability of this vulnerability, especially in a widely used browser like Microsoft Edge, raises concerns about its potential use for deploying various types of malware, further endangering the integrity and security of organizational IT infrastructures.
