CVE-2020-26141: n/a vulnerability

CVE-2020-26141: An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H.

An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-confidentiality protocol.

Security readout for executives and security teams

This CVE affects the ALFA Windows 10 driver 6.1316.1209 for the AWUS036H Wi-Fi adapter. On WPA or WPA2 networks that still support TKIP, nearby attackers may inject traffic and possibly decrypt packets. The practical risk is highest where legacy TKIP remains enabled. Exposure is likely limited to Windows 10 systems using ALFA AWUS036H driver 6.1316.1209 and networks permitting TKIP. Organizations that have fully disabled TKIP and require AES/CCMP are less exposed to this specific issue. Treat this as a legacy wireless risk, not an internet-facing emergency. Prioritize environments that still allow TKIP or use the affected adapter. The main business decision is whether any legacy wireless compatibility justifies keeping TKIP enabled. Mitigation focus: Inventory ALFA AWUS036H use and driver version 6.1316.1209.; Disable TKIP on wireless networks wherever operationally possible.; Require WPA2/WPA3 with AES/CCMP instead of TKIP..
