Description

This security bulletin contains information about 5 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2021-33886)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker on the local network can gain user level command line access through passing a raw external string straight through to printf statements.


2) Insufficient verification of data authenticity (CVE-ID: CVE-2021-33885)

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromsie the target system.

The vulnerability exists due to insufficient verification of data authenticity. A remote attacker can send specially crafted data to the device, leading to execution through lack of cryptographic signatures on critical data sets.


3) Missing Authentication for Critical Function (CVE-ID: CVE-2021-33882)

CWE-ID: CWE-306 - Missing Authentication for Critical Function

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to lack of authentication on proprietary networking commands. A remote attacker can reconfigure the device from an unknown source.


4) Cleartext transmission of sensitive information (CVE-ID: CVE-2021-33883)

CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to software uses insecure communication channel to transmit sensitive information. A remote attacker can obtain sensitive information by snooping the network traffic


5) Arbitrary file upload (CVE-ID: CVE-2021-33884)

CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to insufficient validation of file during file upload. A remote attacker can upload any files to the /tmp directory of the device through the webpage API.
