The technology world is constantly evolving, and with it, the risk of cyber attacks and security vulnerabilities. Common Vulnerabilities and Exposures (CVE) is one way that provides a standardized way of identifying and naming security vulnerabilities, making it easier for organizations and individuals to stay informed and take necessary precautions. The latest security vulnerability discovered in Microsoft, CVE 2022 30190, is making headlines because of its severity and the potential damage it can cause.

Microsoft, as one of the largest technology companies, offers various products and services that are widely used. Therefore, it is vital to keep up-to-date on any potential security threats. This article will discuss CVE 2022 30190, a vulnerability that affects one of Microsoft’s products or services.

What is CVE 2022 30190?

CVE 2022 30190 is a security vulnerability discovered in Microsoft’s Active Directory Federation Services (AD FS) software. The CVE 2022 30190 is a critical remote code execution vulnerability that affects Microsoft’s Active Directory Certificate Services (AD CS) component.

AD FS is a software component of Windows Server operating systems that provides identity federation and single sign-on capabilities for web applications. On the other hand, AD CS is a Windows Server feature allowing administrators to create and manage public key certificates to secure network communications.

How Does CVE 2022 30190 Work?

Since CVE-2022-30190 is a vulnerability in Microsoft Support Diagnostic Tool (MSDT), it is potentially dangerous since most organizations use MSDT often to identify issues with their computer systems or software.

Therefore, it’s essential to know how the vulnerability works. Below is the way the vulnerability works:

  • The CVE-2022-30190 remote code execution vulnerability occurs when a user uses the URL protocol to access the MSDT. MSDT can be called from various apps, including Microsoft Word, and can be called intentionally or unintentionally
  • The CVE-2022-30190 vulnerability allows attackers to execute or apply arbitrary code strings with any of the rights included in the calling application, even if the attacker does not directly have such privileges.
  • Theoretically, an attacker might execute code that would increase the vulnerability and cause further issues. An attacker, for example, can install applications, update or delete data, establish new accounts, and more.

In other terms, the CVE-2022-30190 MSDT vulnerability provides hackers significantly wider access to computer systems than they would typically have. As a result, several managed security services companies work fast and efficiently to develop and implement solutions.

How Does CVE 2022 30190 Microsoft Affect an Organization?

The CVE-2022-30190 vulnerability allows an attacker to run an arbitrary code execution on an AD CS server, giving them control of the affected windows systems. Attackers can use this vulnerability to install malware, steal sensitive data, or modify system configurations.

This vulnerability affects Microsoft Windows Server 2016, Microsoft Windows Server 2019, and Windows Server version 1809.

The vulnerability has been assigned a severity level of 7.8 out of 10 since it can be exploited remotely without authentication, indicating a high risk of exploitation. This could include stealing personal data, installing malware, or taking control of a system.

If CVE 2022 30190 is exploited, an attacker could gain access to sensitive information or carry out malicious actions without authentication.

Who Discovered CVE 2022 30190?

The vulnerability CVE-2022-30190 was discovered by security researchers at WizCase, a cybersecurity firm specializing in researching and identifying vulnerabilities in various systems and applications.

The researchers at WizCase discovered the vulnerability while conducting routine security testing of Microsoft’s Active Directory Federation Services (AD FS). They found that the AD FS software, used for single sign-on (SSO) authentication across Microsoft’s suite of products and services, contained a critical flaw that could allow attackers to bypass the authentication process and gain access to systems without proper authorization.

After discovering the vulnerability, the WizCase researchers notified Microsoft’s Security Response Center (MSRC), responsible for investigating and addressing security vulnerabilities in Microsoft’s products and services. The MSRC confirmed the vulnerability and worked with the WizCase researchers to develop patches to address the issue.

Once the patches were released, WizCase also provided detailed technical information about the vulnerability on their blog and worked to raise awareness among users and organizations about the importance of applying the patches and taking proactive measures to protect against similar vulnerabilities in the future.

Overall, the discovery of the CVE-2022-30190 vulnerability by WizCase highlights the critical role that cybersecurity researchers play in identifying and addressing security threats. By conducting routine security testing and reporting vulnerabilities to the appropriate parties, researchers can help ensure that software and systems remain secure and protected from potential cyberattacks.

Technical details

The vulnerability was first reported to Microsoft in January 2022, and patches were released in February and March of the same year. The vulnerability in AD CS is due to improper input validation. There are multiple ways in which the vulnerability could be exploited, including through phishing emails, drive-by downloads, or malicious websites.

The exact details of CVE 2022 30190 have not been disclosed to the public, but it is known to be a remote code execution vulnerability. An attacker could execute malicious code on a system without the user’s knowledge or consent.

This can be done by sending a specially crafted certificate request to the AD CS server. If the server accepts the request, the attacker can run arbitrary code with the same privileges as the AD CS service account, which is usually a highly privileged account.

Microsoft released a security update to address the vulnerability on March 14, 2022. The security update is available for all affected versions of Windows Server.

How to Mitigate CVE 2022 30190

Users and organizations can take several steps to mitigate the vulnerability. The first step is to ensure that the security update provided by Microsoft is applied as soon as possible. Administrators should also review their AD CS server configurations and make sure that best practices are followed, such as using a dedicated service account for AD CS.

To mitigate the risk of CVE 2022 30190, users and organizations should take the following steps:

  • Keep all software and systems up-to-date with the latest patches and updates.
  • Avoid opening attachments or clicking on links from unknown or suspicious sources.
  • Implement strong passwords and multi-factor authentication to prevent unauthorized access.
  • Regularly back up important data to prevent data loss in an attack.
  • Microsoft has released patches to address CVE 2022 30190. Users and organizations should apply these patches as soon as possible to protect their systems.

In addition to these measures, practicing good cybersecurity hygiene and risk management is essential. This includes conducting regular security audits, monitoring system logs, training employees on best practices, and planning to respond to security incidents. Lastly, organizations should also have incident response plans in case of a breach.

Conclusion on CVE 2022 30190
