CyberRota Analysis

AI-Generated

The vulnerability affects Intel PROSet/Wireless WiFi Software for Windows, allowing unprivileged attackers to escalate privileges through improper authentication in device drivers. This could lead to local code execution with minimal effort, requiring no user interaction, and potentially compromising system confidentiality. Organizations using affected versions of this software should prioritize patching to mitigate the risk of unauthorized access and potential data exposure.

Original NVD Description

Improper authentication for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable local code execution. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (low) and availability (low) impacts.
