CVE-2024-38193 describes a privilege escalation vulnerability in the Windows Ancillary Function Driver for WinSock. This vulnerability allows local attackers to gain elevated privileges, potentially granting them SYSTEM-level access. With a CVSS score of 7.8, this is classified as a high-severity vulnerability, making it critical for organizations to address. The risk to organizations includes unauthorized access and control over systems, which could lead to severe operational impacts.
The vulnerability is actively exploited in the wild, as indicated by its inclusion in the Known Exploited Vulnerabilities (KEV) catalog. Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. The urgency is underscored by the potential for local attackers to exploit this flaw with relative ease, making it imperative to implement remediation strategies without delay.
Given the high-profile nature of this vulnerability, defenders should not only patch affected systems but also consider auditing their environments for any indicators of compromise. Ensuring that security measures are in place will help defend against potential exploitation attempts leveraging this vulnerability.
Organizations using Windows versions affected by this vulnerability include Windows 10 (all versions from 1507 to 22H2), Windows 11 (21H2 to 24H2), and several versions of Windows Server. The wide range of impacted versions increases the urgency for organizations to take immediate action.
Vulnerability Details
The official description of CVE-2024-38193 states that it is a vulnerability in the Windows Ancillary Function Driver for WinSock, leading to elevation of privilege. The CVSS score of 7.8 classifies this vulnerability as high severity, indicating a significant risk to organizations. The vulnerability affects multiple Microsoft Windows products, including various versions of Windows 10 and Windows 11, as well as several Windows Server versions. It was published on August 13, 2024, and is categorized under CWE-416.
Technical Analysis
The root cause of CVE-2024-38193 stems from improper handling of certain operations within the Windows Ancillary Function Driver for WinSock. This vulnerability allows attackers with local access to exploit the flaw and gain elevated privileges. The attack vector is local, meaning that an attacker must have physical or remote access to the machine to execute the exploit.
The attack complexity is low, requiring minimal skill or resources. Privileges required to exploit this vulnerability are low, and no user interaction is necessary, making it particularly dangerous. The impacts of a successful exploit include high confidentiality, integrity, and availability impacts, as the attacker can gain full control over the affected system.
Risk & Impact Analysis
The real-world deployment risk of CVE-2024-38193 is significant due to the potential for local users to gain SYSTEM privileges. This vulnerability can be exploited in environments where user access controls are insufficient, leading to unauthorized access and control over critical systems. The blast radius potential is extensive, as numerous Windows versions across both consumer and server platforms are affected.
Given the CVSS score and its classification as a known exploited vulnerability, organizations should assess their exposure to this threat and prioritize remediation efforts. The urgency of response is high, with a critical remediation priority placed on applying patches or implementing workarounds as soon as they are available.
