CVE-2022-21930 is a medium-severity vulnerability affecting Microsoft Edge (Chromium-based) that allows remote code execution. The CVSS score for this vulnerability is 4.2, indicating a medium level of risk. This vulnerability is classified under the attack vector of NETWORK with high attack complexity, meaning that while exploitation is possible, it requires specific conditions, including user interaction.
The exploitation of this vulnerability poses a risk to organizations as attackers may leverage this weakness to execute arbitrary code on affected systems. The urgency for defenders to address this issue is high, as the implications of successful exploitation could lead to unauthorized actions within the context of the user.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. The vulnerability was published on January 11, 2022, and has been modified since its initial disclosure, which further underscores the necessity for prompt action.
Currently, there is no known public exploit or proof of concept available for this vulnerability, but the potential for exploitation remains. Organizations should keep abreast of updates from Microsoft to ensure they are taking appropriate actions.
Vulnerability Details
According to the official description, CVE-2022-21930 is a remote code execution vulnerability in Microsoft Edge (Chromium-based). The vulnerability allows attackers to execute arbitrary code on a target system if the user is tricked into opening a specially crafted web page. The CVSS score of 4.2 signifies a medium severity level, indicating that while the issue is serious, it does not represent an immediate critical threat.
The vulnerability affects the Microsoft Edge (Chromium-based) browser versions prior to 97.0.1072.55. The publication date of this vulnerability was January 11, 2022. Organizations utilizing this browser should be aware of the potential impact and take necessary actions to secure their systems.
Technical Analysis
The root cause of CVE-2022-21930 stems from a flaw in the way Microsoft Edge processes certain web content, leading to potential remote code execution. The attack vector is network-based, meaning an attacker could exploit this vulnerability through network access, but it requires high complexity due to the necessity of user interaction.
In terms of privileges required, none are necessary for the attacker; however, user interaction is required to execute the attack, making this a moderately complex vulnerability to exploit. The confidentiality and integrity impacts are both rated as low, while there is no availability impact, as the vulnerability does not affect the availability of the system.
Risk & Impact Analysis
The real-world risk posed by CVE-2022-21930 is significant, particularly for organizations relying on Microsoft Edge (Chromium-based) as their primary browser. Attackers may leverage this vulnerability to execute arbitrary code, potentially leading to unauthorized access and control over affected systems. This could enable data exfiltration, system manipulation, or further attacks within the organizational network.
Organizations should assess their deployment of Microsoft Edge and the potential blast radius of an attack exploiting this vulnerability. With a CVSS score of 4.2, the urgency for organizations to patch this vulnerability is classified as medium, and it should be included in their priority patch cycle.
