Vulnerabilities in this advisory

• CVE-2022-46143 — CVE-2022-46143 · CWE-1284

  Affected devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer that potentially contains previously allocated data.

• CVE-2023-44318 — CVE-2023-44318 · CWE-321

  Affected devices use a hardcoded key to obfuscate the configuration backup that an administrator can export from the device. This could allow an authenticated attacker with administrative privileges or an attacker that obtains a configuration backup to extract configuration information from the exported file.

• CVE-2023-44319 — CVE-2023-44319 · CWE-328

  Affected devices use a weak checksum algorithm to protect the configuration backup that an administrator can export from the device. This could allow an authenticated attacker with administrative privileges or an attacker that tricks a legitimate administrator to upload a modified configuration file to change the configuration of an affected device.

• CVE-2023-44322 — CVE-2023-44322 · CWE-252

  Affected devices can be configured to send emails when certain events occur on the device. When presented with an invalid response from the SMTP server, the device triggers an error that disrupts email sending. An attacker with access to the network can use this to do disable notification of users when certain events occur.

• CVE-2023-44373 — CVE-2023-44373 · CWE-74

  Affected devices do not properly sanitize an input field. This could allow an authenticated remote attacker with administrative privileges to inject code or spawn a system root shell. Follow-up of CVE-2022-36323.

• CVE-2023-44374 — CVE-2023-44374 · CWE-567

  Affected devices allow to change the password, but insufficiently check which password is to be changed. With this an authenticated attacker could, under certain conditions, be able to change the password of another, potential admin user allowing her to escalate her privileges.

• CVE-2023-49691 — CVE-2023-49691 · CWE-78

  An Improper Neutralization of Special Elements used in an OS Command with root privileges vulnerability exists in the handling of the DDNS configuration. This could allow malicious local administrators to issue commands on system level after a successful IP address update.
