FKIE_CVE-2020-27302

Vulnerability from fkie_nvd - Published: 2021-06-04 13:15 - Updated: 2024-11-21 05:21
Severity ?
8.0 (High) - CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.

FKIE_CVE-2020-25855

Vulnerability from fkie_nvd - Published: 2021-02-03 17:15 - Updated: 2024-11-21 05:18
Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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.

FKIE_CVE-2020-25856

Vulnerability from fkie_nvd - Published: 2021-02-03 17:15 - Updated: 2024-11-21 05:18
Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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.

FKIE_CVE-2020-25854

Vulnerability from fkie_nvd - Published: 2021-02-03 17:15 - Updated: 2024-11-21 05:18
Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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 (GCVE-0-2020-25853)

Vulnerability from cvelistv5 – Published: 2021-02-03 16:49 – Updated: 2024-08-04 15:49
VLAI?
Summary
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.
Severity ?
No CVSS data available.

Summary
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.
Severity ?

CVE-2020-25853 (GCVE-0-2020-25853)

Vulnerability from nvd – Published: 2021-02-03 16:49 – Updated: 2024-08-04 15:49
VLAI?
Summary
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.
Severity ?
No CVSS data available.

Summary
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.
Severity ?
No CVSS data available.
