So What's The Issue?
TP-Link has discovered two vulnerabilities affecting its Omada gateway devices. One of them (CVE-2025-6542) is rated a critical severity of 9.3 out of 10. The most unfortunate part of this vulnerability is that it's exploitable remotely, without authenticated access.Another vulnerability (CVE-2025-6541) is of lesser severity (8.6 out of 10), but an attacker must be logged into the device.
Why Is This Important?
These weaknesses allow attackers to execute commands within the router's OS - in short, they can completely take over your device. Once they do that, they can:• Update your network settings
• Monitor or steal your internet traffic
• Install malware or spyware
• Prevent you from accessing your own system
