Description

This security bulletin contains information about 6 vulnerabilities.

1) Improper Authentication (CVE-ID: CVE-2022-26845)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/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 bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests in firmware. A remote attacker can bypass authentication process and gain elevated privileges on the system.

2) NULL pointer dereference (CVE-ID: CVE-2022-27497)

CWE-ID: CWE-476 - NULL Pointer Dereference

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

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in firmware. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

3) Improper Authentication (CVE-ID: CVE-2022-29893)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/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 bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests in firmware. A remote user can bypass authentication process and gain elevated privileges on the system.

4) Improper Authentication (CVE-ID: CVE-2021-33159)

CWE-ID: CWE-287 - Improper Authentication

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

The vulnerability allows a local user to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests in firmware. A local administrator can bypass authentication process and gain elevated privileges on the system.

5) Input validation error (CVE-ID: CVE-2022-29466)

CWE-ID: CWE-20 - Improper input validation

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

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in firmware. A local user can pass specially crafted input to the application and perform a denial of service (DoS) attack.

6) Input validation error (CVE-ID: CVE-2022-29515)

CWE-ID: CWE-20 - Improper input validation

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

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to missing release of memory after effective lifetime in firmware. A local administrator can pass specially crafted input to the application and perform a denial of service (DoS) attack.
