|---|---|---|---|---|---|
| CVE-2021-21967 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 7.1 HIGH | 5.9 MEDIUM |
| An out-of-bounds write vulnerability exists in the OTA update task functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A specially-crafted MQTT payload can lead to denial of service. An attacker can perform a man-in-the-middle attack to trigger this vulnerability. | |||||
| CVE-2021-21962 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 6.8 MEDIUM | 8.1 HIGH |
| A heap-based buffer overflow vulnerability exists in the OTA Update u-download functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A series of specially-crafted MQTT payloads can lead to remote code execution. An attacker must perform a man-in-the-middle attack in order to trigger this vulnerability. | |||||
| CVE-2021-21964 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 7.1 HIGH | 7.4 HIGH |
| A denial of service vulnerability exists in the Modbus configuration functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. Specially-crafted network packets can lead to denial of service. An attacker can send a malicious packet to trigger this vulnerability. | |||||
| CVE-2021-21970 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 6.8 MEDIUM | 8.1 HIGH |
| An out-of-bounds write vulnerability exists in the HandleSeaCloudMessage functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. The HandleIncomingSeaCloudMessage function uses at [3] the json_object_get_string to populate the p_name global variable. The p_name is only 0x80 bytes long, and the total MQTT message could be up to 0x201 bytes. Because the function json_object_get_string will fill str based on the length of the json’s value and not the actual str size, this would result in a possible out-of-bounds write. | |||||
| CVE-2021-21961 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 7.5 HIGH | 10.0 CRITICAL |
| A stack-based buffer overflow vulnerability exists in the NBNS functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A specially-crafted network packet can lead to remote code execution. An attacker can send a malicious packet to trigger this vulnerability. | |||||
| CVE-2021-21963 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 4.3 MEDIUM | 5.9 MEDIUM |
| An information disclosure vulnerability exists in the Web Server functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A specially-crafted man-in-the-middle attack can lead to a disclosure of sensitive information. An attacker can perform a man-in-the-middle attack to trigger this vulnerability. | |||||
| CVE-2021-21969 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 6.8 MEDIUM | 8.1 HIGH |
| An out-of-bounds write vulnerability exists in the HandleSeaCloudMessage functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. The HandleIncomingSeaCloudMessage function uses at [4] the json_object_get_string to populate the p_payload global variable. The p_payload is only 0x100 bytes long, and the total MQTT message could be up to 0x201 bytes. Because the function json_object_get_string will fill str based on the length of the json’s value and not the actual str size, this would result in a possible out-of-bounds write. | |||||
| CVE-2021-21971 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 4.3 MEDIUM | 5.9 MEDIUM |
| An out-of-bounds write vulnerability exists in the URL_decode functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A specially-crafted MQTT payload can lead to an out-of-bounds write. An attacker can perform a man-in-the-middle attack to trigger this vulnerability. | |||||
| CVE-2021-21968 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 6.8 MEDIUM | 8.3 HIGH |
| A file write vulnerability exists in the OTA update task functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A specially-crafted MQTT payload can lead to arbitrary file overwrite. An attacker can perform a man-in-the-middle attack to trigger this vulnerability. | |||||
| CVE-2021-21960 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 7.5 HIGH | 10.0 CRITICAL |
| A stack-based buffer overflow vulnerability exists in both the LLMNR functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. A specially-crafted network packet can lead to remote code execution. An attacker can send a malicious packet to trigger this vulnerability. | |||||
| CVE-2021-21959 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 6.8 MEDIUM | 8.1 HIGH |
| A misconfiguration exists in the MQTTS functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. This misconfiguration significantly simplifies a man-in-the-middle attack, which directly leads to control of device functionality. | |||||
| CVE-2021-21965 | 1 Sealevel | 2 Seaconnect 370w, Seaconnect 370w Firmware | 2023-12-10 | 6.4 MEDIUM | 9.3 CRITICAL |
| A denial of service vulnerability exists in the SeaMax remote configuration functionality of Sealevel Systems, Inc. SeaConnect 370W v1.3.34. Specially-crafted network packets can lead to denial of service. An attacker can send a malicious packet to trigger this vulnerability. | |||||
