description

PLANET GS-5220-8P2T2S hardware version 3.0 running firmware before 3.2412b261008 is affected by a stack-based buffer overflow in web request handling. An unauthenticated remote attacker able to reach the device web interface could trigger memory corruption and potentially disrupt the device.

mitigation

Upgrade affected devices to firmware version 3.2412b261008. Until upgrades are complete, restrict access to the device web interface to trusted management networks.

fixed in 3.2412b261008
