kernel: accepting plaintext data frames in protected networks

An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration.

A vulnerability has been identified in SCALANCE W1748-1 M12 (6GK5748-1GY01-0AA0), SCALANCE W1748-1 M12 (6GK5748-1GY01-0TA0), SCALANCE W1788-1 M12 (6GK5788-1GY01-0AA0), SCALANCE W1788-2 EEC M12 (6GK5788-2GY01-0TA0), SCALANCE W1788-2 M12 (6GK5788-2GY01-0AA0), SCALANCE W1788-2IA M12 (6GK5788-2HY01-0AA0), SCALANCE W721-1 RJ45 (6GK5721-1FC00-0AA0), SCALANCE W721-1 RJ45 (6GK5721-1FC00-0AB0), SCALANCE W722-1 RJ45 (6GK5722-1FC00-0AA0), SCALANCE W722-1 RJ45 (6GK5722-1FC00-0AB0), SCALANCE W722-1 RJ45 (6GK5722-1FC00-0AC0), SCALANCE W734-1 RJ45 (6GK5734-1FX00-0AA0), SCALANCE W734-1 RJ45 (6GK5734-1FX00-0AA6), SCALANCE W734-1 RJ45 (6GK5734-1FX00-0AB0), SCALANCE W734-1 RJ45 (USA) (6GK5734-1FX00-0AB6), SCALANCE W738-1 M12 (6GK5738-1GY00-0AA0), SCALANCE W738-1 M12 (6GK5738-1GY00-0AB0), SCALANCE W748-1 M12 (6GK5748-1GD00-0AA0), SCALANCE W748-1 M12 (6GK5748-1GD00-0AB0), SCALANCE W748-1 RJ45 (6GK5748-1FC00-0AA0), SCALANCE W748-1 RJ45 (6GK5748-1FC00-0AB0), SCALANCE W761-1 RJ45 (6GK5761-1FC00-0AA0), SCALANCE W761-1 RJ45 (6GK5761-1FC00-0AB0), SCALANCE W774-1 M12 EEC (6GK5774-1FY00-0TA0), SCALANCE W774-1 M12 EEC (6GK5774-1FY00-0TB0), SCALANCE W774-1 RJ45 (6GK5774-1FX00-0AA0), SCALANCE W774-1 RJ45 (6GK5774-1FX00-0AA6), SCALANCE W774-1 RJ45 (6GK5774-1FX00-0AB0), SCALANCE W774-1 RJ45 (6GK5774-1FX00-0AC0), SCALANCE W774-1 RJ45 (USA) (6GK5774-1FX00-0AB6), SCALANCE W778-1 M12 (6GK5778-1GY00-0AA0), SCALANCE W778-1 M12 (6GK5778-1GY00-0AB0), SCALANCE W778-1 M12 EEC (6GK5778-1GY00-0TA0), SCALANCE W778-1 M12 EEC (USA) (6GK5778-1GY00-0TB0), SCALANCE W786-1 RJ45 (6GK5786-1FC00-0AA0), SCALANCE W786-1 RJ45 (6GK5786-1FC00-0AB0), SCALANCE W786-2 RJ45 (6GK5786-2FC00-0AA0), SCALANCE W786-2 RJ45 (6GK5786-2FC00-0AB0), SCALANCE W786-2 RJ45 (6GK5786-2FC00-0AC0), SCALANCE W786-2 SFP (6GK5786-2FE00-0AA0), SCALANCE W786-2 SFP (6GK5786-2FE00-0AB0), SCALANCE W786-2IA RJ45 (6GK5786-2HC00-0AA0), SCALANCE W786-2IA RJ45 (6GK5786-2HC00-0AB0), SCALANCE W788-1 M12 (6GK5788-1GD00-0AA0), SCALANCE W788-1 M12 (6GK5788-1GD00-0AB0), SCALANCE W788-1 RJ45 (6GK5788-1FC00-0AA0), SCALANCE W788-1 RJ45 (6GK5788-1FC00-0AB0), SCALANCE W788-2 M12 (6GK5788-2GD00-0AA0), SCALANCE W788-2 M12 (6GK5788-2GD00-0AB0), SCALANCE W788-2 M12 EEC (6GK5788-2GD00-0TA0), SCALANCE W788-2 M12 EEC (6GK5788-2GD00-0TB0), SCALANCE W788-2 M12 EEC (6GK5788-2GD00-0TC0), SCALANCE W788-2 RJ45 (6GK5788-2FC00-0AA0), SCALANCE W788-2 RJ45 (6GK5788-2FC00-0AB0), SCALANCE W788-2 RJ45 (6GK5788-2FC00-0AC0), SCALANCE WAM763-1 (6GK5763-1AL00-7DA0), SCALANCE WAM766-1 (EU) (6GK5766-1GE00-7DA0), SCALANCE WAM766-1 (US) (6GK5766-1GE00-7DB0), SCALANCE WAM766-1 EEC (EU) (6GK5766-1GE00-7TA0), SCALANCE WAM766-1 EEC (US) (6GK5766-1GE00-7TB0), SCALANCE WUM763-1 (6GK5763-1AL00-3AA0), SCALANCE WUM763-1 (6GK5763-1AL00-3DA0), SCALANCE WUM766-1 (EU) (6GK5766-1GE00-3DA0), SCALANCE WUM766-1 (US) (6GK5766-1GE00-3DB0). This CVE refers to Scenario 2 "Abuse the queue for network disruptions" of CVE-2022-47522. Affected devices can be tricked into enabling its power-saving mechanisms for a victim client. This could allow a physically proximate attacker to execute disconnection and denial-of-service attacks.

kernel: wifi frame payload being parsed incorrectly as an L2 frame

The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.

Affected devices use a weak encryption scheme to encrypt the debug zip file. This could allow an authenticated attacker to decrypt the contents of the file and retrieve debug information about the system.

Affected devices store the CLI user passwords encrypted in flash memory. Attackers with physical access to the device could retrieve the file and decrypt the CLI user passwords.

Affected devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer that potentially contains previously allocated data.
