Beware of Wireless Networking Vulnerability in Popular Wireless Devices

CVSScvssV3_1: 7.5

The wireless networking industry has seen yet another vulnerability disclosed. CVE-2023-33089 affects how many wireless devices from major manufacturers parse wireless network configuration data.

This vulnerability could allow a remote attacker to cause a transient denial-of-service (DOS) condition on affected devices. By sending specially crafted wireless network setup packets, an attacker may be able to crash certain processes related to wireless network card management or bring down the wireless network interface temporarily.

While this alone does not allow full device takeover or data theft, it could disrupt wireless connectivity and network availability for users. Manufacturers have rated the severity as high with a CVSS score of 7.5. Popular wireless routers, access points and client devices from brands like Cisco, Arris, Netgear and TP-Link are said to be impacted.

The best way to protect yourself is to ensure your wireless device firmware is always kept up to date. Manufacturers are likely working on patches to address this issue, so vigilantly applying any updates issued for your devices is recommended. You can also consider disabling remote management interfaces if possible, changing default credentials, and enabling strong encryption to avoid attacks targeting default configurations.

Staying on top of advisory updates from manufacturers and security researchers is key to mitigating risks from wireless vulnerabilities as they are discovered. Let’s hope a patch is released soon to plug this potential disruption to wireless networking.
