Description

This security bulletin contains information about 6 vulnerabilities.


1) Missing Authentication for Critical Function (CVE-ID: CVE-2022-29957)

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

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


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to missing authentication for several protocols. A remote attacker on the local network can invoke desired functionality or cause a denial of service (DoS) condition.


2) Use of hard-coded credentials (CVE-ID: CVE-2022-29962)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

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


The vulnerability allows a local user to gain full access to vulnerable system.

The vulnerability exists due to presence of hard-coded credentials in the FTP service. A local user can access the affected system using the hard-coded credentials.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Use of hard-coded credentials (CVE-ID: CVE-2022-29963)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

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


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

The vulnerability exists due to presence of hard-coded credentials within the read-only Telnet service. A remote administrator on the local network can gain access to sensitive information on the target system.


4) Use of hard-coded credentials (CVE-ID: CVE-2022-29964)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

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


The vulnerability allows a local user to gain full access to vulnerable system.

The vulnerability exists due to presence of hard-coded credentials within the SSH service. A local user can access the affected system using the hard-coded credentials.


5) Insufficient verification of data authenticity (CVE-ID: CVE-2022-30260)

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

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


The vulnerability allows a local user to compromise the target system.

The vulnerability exists due to the firmware images are not signed and rely on insecure checksums for regular integrity checks. A local administrator can execute arbitrary code on the target system.


6) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-29965)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/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 use of a broken or risky cryptographic algorithm. A remote attacker on the local network can gain access to privileged operations in the maintenance interface.
