Summary
Improper authentication in Intel(R) PROSet/Wireless WiFi Software for Windows may allow an escalation of privilege. An unprivileged attacker with an unauthenticated user and a low complexity attack may enable local code execution. The attack requires local access, no user interaction, and may impact confidentiality, integrity, and availability.
Risk Assessment
Local code execution could allow an attacker to take control of the system, potentially leading to a breach of data and resources.
Recommendation
It is recommended to update Intel(R) PROSet/Wireless WiFi Software to the latest version that fixes the authentication issue.
Original NVD description (English source)
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.
