Description
This security bulletin contains information about 7 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2022-46143)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to gain access to sensitive information on the system.
The vulnerability exists due to the affected device does not check the TFTP blocksize correctly. A remote administrator can read from an uninitialized buffer that potentially contains previously allocated data.
2) Reversible One-Way Hash (CVE-ID: CVE-2023-44319)
CWE-ID: CWE-328 - Use of Weak Hash
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a user attacker to compromise the target system.
The vulnerability exists due to use of a weak checksum algorithm to protect the configuration backup that an administrator can export from the device. A remote administrator can upload a modified configuration file to change the configuration of an affected device.
3) Unchecked Return Value (CVE-ID: CVE-2023-44322)
CWE-ID: CWE-252 - Unchecked Return Value
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the affected devices can be configured to send emails when certain events occur on the device. A remote attacker can perform a denial of service (DoS) attack.
CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation. A remote administrator can execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Improper access control (CVE-ID: CVE-2023-44374)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/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 gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to affected devices insufficiently check which password is to be changed. A remote user can change the password and gain elevtaed privileges.
CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote administrator can inject arbitrary code or spawn a system root shell.
7) OS Command Injection (CVE-ID: CVE-2023-49691)
CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the handling of the DDNS configuration. A remote administrator can pass specially crafted data to the application and execute arbitrary OS commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
