Vulnerability from fkie_nvd - Published: 2020-09-30 18:15 - Updated: 2024-11-21 04:33
Severity
5.4 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
Summary
A partial authentication bypass vulnerability exists on Realtek RTL8812AR 1.21WW, RTL8196D 1.0.0, RTL8192ER 2.10, and RTL8881AN 1.09 devices. The vulnerability allows sending an unencrypted data frame to a WPA2-protected WLAN router where the packet is routed through the network. If successful, a response is sent back as an encrypted frame, which would allow an attacker to discern information or potentially modify data.
