|---|---|---|---|---|---|
| CVE-2020-27302 | 1 Realtek | 4 Rtl8195a, Rtl8195a Firmware, Rtl8710c and 1 more | 2024-11-21 | 7.7 HIGH | 8.0 HIGH |
| A stack buffer overflow in Realtek RTL8710 (and other Ameba-based devices) can lead to remote code execution via the "memcpy" function, when an attacker in Wi-Fi range sends a crafted "Encrypted GTK" value as part of the WPA2 4-way-handshake. | |||||
| CVE-2020-27301 | 1 Realtek | 4 Rtl8195a, Rtl8195a Firmware, Rtl8710c and 1 more | 2024-11-21 | 7.7 HIGH | 8.0 HIGH |
| A stack buffer overflow in Realtek RTL8710 (and other Ameba-based devices) can lead to remote code execution via the "AES_UnWRAP" function, when an attacker in Wi-Fi range sends a crafted "Encrypted GTK" value as part of the WPA2 4-way-handshake. | |||||
| CVE-2020-25857 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| The function ClientEAPOLKeyRecvd() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an rtl_memcpy() operation, resulting in a stack buffer overflow which can be exploited for denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker does not need to know the network's PSK. | |||||
| CVE-2020-25856 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
| The function DecWPA2KeyData() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an rtl_memcpy() operation, resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. | |||||
| CVE-2020-25855 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
| The function AES_UnWRAP() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for a memcpy() operation, resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. | |||||
| CVE-2020-25854 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
| The function DecWPA2KeyData() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an internal function, rt_arc4_crypt_veneer() or _AES_UnWRAP_veneer(), resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. | |||||
| CVE-2020-25853 | 1 Realtek | 2 Rtl8195a, Rtl8195a Firmware | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| The function CheckMic() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an internal function, _rt_md5_hmac_veneer() or _rt_hmac_sha1_veneer(), resulting in a stack buffer over-read which can be exploited for denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker does not need to know the network's PSK. | |||||
