Zyxel warns of several vulnerabilities in some of its devices. These make firewalls, access points and AP controllers vulnerable, writes the network component manufacturer in the release. An attacker could use the security gaps to circulate malicious scripts in the network, run arbitrary program code on devices, cause them to crash or switch off two-factor authentication.
In its security advisory, Zyxel provides a list of the devices affected by the vulnerabilities and the impact of the vulnerabilities. According to this document, the company is providing secure firmware updates for the affected and still supported devices that address the vulnerabilities.
At the beginning of May, security researchers warned of serious security gaps in Aruba and Avaya network switches. The vulnerabilities allow cybercriminals to take control of the devices. Patches are also available for this, as you can find out here.
