Summary
The affected software is the firmware of the Zyxel GS1900-24E network switch, specifically its web-based management CGI program. An attacker on the same local network, without needing to log in, could send a specially crafted web request that corrupts memory and may allow them to run operating system commands on the device.
Read the original description
An out-of-bounds write vulnerability in the CGI program of Zyxel GS1900-24E firmware versions through 2.90(AAHK.2)C0 could allow an unauthenticated adjacent attacker to exploit the flaw and potentially execute OS commands via a crafted HTTP request.
