Zyxel has released patches to address 15 security issues impacting network-attached storage (NAS), firewall, and access point (AP) devices, including three critical flaws that could lead to authentication bypass and command injection.
The three vulnerabilities are listed below -
Also patched by Zyxel are three high-severity flaws (CVE-2023-35137, CVE-2023-37927, and CVE-2023-37928) that, if successfully exploited, could allow attackers to obtain system information and execute arbitrary commands. It’s worth noting that both CVE-2023-37927 and CVE-2023-37928 require authentication.
The flaws impact the following models and versions -
The advisory comes days after the Taiwanese networking vendor shipped fixes for nine flaws in select firewall and access point (AP) versions, some of which could be weaponized to access system files and administrator logs, as well as cause a denial-of-service (DoS) condition.
With Zyxel devices often exploited by threat actors, it’s highly recommended that users apply the latest updates to mitigate potential threats.
