Vulnerability Details
This vulnerability allows remote code execution in Microsoft Edge (Chromium-based). The CVSS score is 7.6, which signifies a high severity. It is classified under CWE-122, indicating an issue related to improper neutralization of special elements in output used by a downstream component.
The affected product is the Microsoft Edge Chromium, with all versions prior to the vendor patch vulnerable. The vulnerability was published on October 17, 2024.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user input, which can be exploited by attackers. The attack vector is network-based, meaning that an attacker could exploit the vulnerability remotely. The attack complexity is low, and it requires low privileges but necessitates user interaction to trigger the exploit.
The confidentiality and integrity impacts are both high, indicating that an attacker could potentially access sensitive information and alter data. The availability impact is low, meaning services may remain operational even if the vulnerability is exploited.
Risk & Impact Analysis
Real-world deployment of Microsoft Edge in organizational environments increases the risk associated with this vulnerability. Should an attacker exploit the vulnerability, they could execute arbitrary code, potentially leading to unauthorized access and compromise of sensitive data.
The potential blast radius is significant considering the widespread use of Microsoft Edge. Organizations should assess their exposure and prioritize remediation efforts based on this risk assessment.
Given the CVSS score of 7.6 and the absence from the Known Exploited Vulnerabilities (KEV) catalog, organizations should still consider this vulnerability a priority for their patch cycle.
