Vulnerability Details

The official description of CVE-2022-24507 states that it is a Windows Ancillary Function Driver for WinSock Elevation of Privilege Vulnerability. The vulnerability affects multiple versions of Microsoft Windows, including Windows 10 (20H2, 21H1, 21H2, 1607, 1809, 1909), Windows 11, and Windows Server (20H2, 2016, 2019, 2022).

The CVSS score for this vulnerability is 7.8, classified as high severity. The attack vector is local, and it requires low attack complexity with low privileges required to exploit it.

The potential impacts of this vulnerability include high confidentiality, integrity, and availability impacts, indicating a serious threat to systems that are not patched.

Technical Analysis

The root cause of CVE-2022-24507 lies in the Windows Ancillary Function Driver, which does not properly handle certain input, leading to an elevation of privilege vulnerability. The attack vector is local, meaning that an attacker must have physical access to the machine or be able to execute code locally.

The attack complexity is low, and no user interaction is required to exploit the vulnerability. This could mean that an attacker could run malicious code that escalates privileges without any further action needed from the user.

The impact on confidentiality, integrity, and availability is high, suggesting that an attacker could compromise sensitive information, manipulate data, or disrupt service availability.

Risk & Impact Analysis

The real-world deployment risk associated with CVE-2022-24507 is high, given the number of affected systems and the severity of the vulnerability. Organizations that run unpatched versions of Windows are at risk of unauthorized access and control by attackers who leverage this vulnerability.

The blast radius potential is significant, as this vulnerability affects multiple versions of Windows across various environments, including enterprise and server setups. Organizations should assess their risk based on their deployment of affected systems.

Given the high CVSS score and the fact that this vulnerability is not currently in the KEV catalog, organizations should still treat it with urgency and address it in their patch cycle.
