Zyxel · Zyxel Nwa110Ax · CVE-2022-45854
**Name of the Vulnerable Software and Affected Versions**
Zyxel NWA110AX versions prior to 6.50(ABTG.0)C0
**Description**
The issue is related to an improper check for unusual conditions in the firmware, which could allow a LAN attacker to cause a temporary denial-of-service (DoS) by sending crafted VLAN frames if the MAC address of the vulnerable AP were intercepted by the attacker. Additionally, there is a vulnerability in the implementation of the command-line interface (CLI) of Zyxel network device firmware, related to the failure to neutralize special elements used in the command of the operating system, which could allow a remote attacker to execute arbitrary commands.
**Recommendations**
For versions prior to 6.50(ABTG.0)C0, update to version 6.50(ABTG.0)C0 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable AP to minimize the risk of exploitation. Avoid using the vulnerable CLI interface until the issue is resolved.
