CVE-2021-35394 1 Realtek 1 Realtek Jungle Sdk 2023-12-10 10.0 HIGH 9.8 CRITICAL
Realtek Jungle SDK version v2.x up to v3.4.14B provides a diagnostic tool called 'MP Daemon' that is usually compiled as 'UDPServer' binary. The binary is affected by multiple memory corruption vulnerabilities and an arbitrary command injection vulnerability that can be exploited by remote unauthenticated attackers.
CVE-2021-35392 1 Realtek 1 Jungle Sdk 2023-12-10 7.8 HIGH 7.5 HIGH
Realtek Jungle SDK version v2.x up to v3.4.14B provides a 'WiFi Simple Config' server that implements both UPnP and SSDP protocols. The binary is usually named wscd or mini_upnpd and is the successor to miniigd. The server is vulnerable to a heap buffer overflow that is present due to unsafe crafting of SSDP NOTIFY messages from received M-SEARCH messages ST header.
CVE-2020-27302 1 Realtek 4 Rtl8195a, Rtl8195a Firmware, Rtl8710c and 1 more 2023-12-10 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-2021-35395 1 Realtek 1 Realtek Jungle Sdk 2023-12-10 10.0 HIGH 9.8 CRITICAL
Realtek Jungle SDK version v2.x up to v3.4.14B provides an HTTP web server exposing a management interface that can be used to configure the access point. Two versions of this management interface exists: one based on Go-Ahead named webs and another based on Boa named boa. Both of them are affected by these vulnerabilities. Specifically, these binaries are vulnerable to the following issues: - stack buffer overflow in formRebootCheck due to unsafe copy of submit-url parameter - stack buffer overflow in formWsc due to unsafe copy of submit-url parameter - stack buffer overflow in formWlanMultipleAP due to unsafe copy of submit-url parameter - stack buffer overflow in formWlSiteSurvey due to unsafe copy of ifname parameter - stack buffer overflow in formStaticDHCP due to unsafe copy of hostname parameter - stack buffer overflow in formWsc due to unsafe copy of 'peerPin' parameter - arbitrary command execution in formSysCmd via the sysCmd parameter - arbitrary command injection in formWsc via the 'peerPin' parameter Exploitability of identified issues will differ based on what the end vendor/manufacturer did with the Realtek SDK webserver. Some vendors use it as-is, others add their own authentication implementation, some kept all the features from the server, some remove some of them, some inserted their own set of features. However, given that Realtek SDK implementation is full of insecure calls and that developers tends to re-use those examples in their custom code, any binary based on Realtek SDK webserver will probably contains its own set of issues on top of the Realtek ones (if kept). Successful exploitation of these issues allows remote attackers to gain arbitrary code execution on the device.
CVE-2020-27301 1 Realtek 4 Rtl8195a, Rtl8195a Firmware, Rtl8710c and 1 more 2023-12-10 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-2020-23539 1 Realtek 2 Rtl8723de, Rtl8723de Firmware 2023-12-10 7.8 HIGH 7.5 HIGH
An issue was discovered in Realtek rtl8723de BLE Stack <= 4.1 that allows remote attackers to cause a Denial of Service via the interval field to the CONNECT_REQ message.
CVE-2021-27372 1 Realtek 2 Xpon Rtl9601d, Xpon Rtl9601d Software Development Kit 2023-12-10 10.0 HIGH 9.8 CRITICAL
Realtek xPON RTL9601D SDK 1.9 stores passwords in plaintext which may allow attackers to possibly gain access to the device with root permissions via the build-in network monitoring tool and execute arbitrary commands.
CVE-2021-32537 1 Realtek 1 Hda Driver 2023-12-10 4.9 MEDIUM 6.5 MEDIUM
Realtek HAD contains a driver crashed vulnerability which allows local side attackers to send a special string to the kernel driver in a user’s mode. Due to unexpected commands, the kernel driver will cause the system crashed.
CVE-2019-18990 1 Realtek 8 Rtl8192er, Rtl8192er Firmware, Rtl8196d and 5 more 2023-12-10 4.8 MEDIUM 5.4 MEDIUM
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.
CVE-2020-25855 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2023-12-10 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-2020-25857 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2023-12-10 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 2023-12-10 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-2020-25853 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2023-12-10 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.
CVE-2020-25854 1 Realtek 2 Rtl8195a, Rtl8195a Firmware 2023-12-10 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-2020-9395 1 Realtek 8 Rtl8195am, Rtl8195am Firmware, Rtl8710af and 5 more 2023-12-10 4.9 MEDIUM 8.0 HIGH
An issue was discovered on Realtek RTL8195AM, RTL8711AM, RTL8711AF, and RTL8710AF devices before 2.0.6. A stack-based buffer overflow exists in the client code that takes care of WPA2's 4-way-handshake via a malformed EAPOL-Key packet with a long keydata buffer.
CVE-2020-12773 1 Realtek 1 Adsl Router Soc Firmware 2023-12-10 6.5 MEDIUM 8.8 HIGH
A security misconfiguration vulnerability exists in the SDK of some Realtek ADSL/PON Modem SoC firmware, which allows attackers using a default password to execute arbitrary commands remotely via the build-in network monitoring tool.
