Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Missing Authentication for Critical Function (CVE-ID: CVE-2022-29957)
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)
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)
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)
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)
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)
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.
