Description

This security bulletin contains information about 6 secuirty vulnerabilities.


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

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)

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)

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)

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)

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)

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.
