Apple released an iOS update Monday to fix a serious vulnerability that could allow attackers to remotely execute malicious code on the Broadcom Wi-Fi chips used in iPhones, iPads and iPods.

The vulnerability is a stack buffer overflow in the feature that handles authentication responses for the fast BSS transition feature of the 802.11r protocol, also known as fast roaming. This feature allows devices to move easily and securely between different wireless base stations in the same domain.

Hackers can exploit the flaw to execute code in the context of the Wi-Fi chip’s firmware if they’re within the wireless range of the targeted devices.

The issue is one of several flaws found by Google Project Zero researcher Gal Beniamini in the firmware of Broadcom Wi-Fi chips. Some of these vulnerabilities also affect Android devices and have been patched as part of Android’s April security bulletin.

Unpatched vulnerability puts Ubiquiti networking products at risk

An unpatched command injection vulnerability could allow hackers to take over enterprise networking products from Ubiquiti Networks.

The vulnerability was discovered by researchers from SEC Consult and allows authenticated users to inject arbitrary commands into the web-based administration interface of affected devices. These commands would be executed on the underlying operating system as root, the highest privileged account.

Because it requires authentication, the vulnerability’s impact is somewhat reduced, but it can still be exploited remotely through cross-site request forgery (CSRF). This is an attack technique that involves forcing a user’s browser to send unauthorized requests to specifically crafted URLs in the background when they visit attacker-controlled websites.

To keep private Wi-Fi networks secure, encryption is a must-have — and using strong passwords or passphrases is necessary to prevent the encryption from being cracked. But don’t stop there! Many other settings, features and situations can make your Wi-Fi network as much or even more insecure as when you use a weak password. Make sure you’re not leaving your network vulnerable by doing any of the following.
