Administrative root code execution via HTTP buffer overflow
Published Mar 6, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Cisco Small Business 100, 300, and 500 Series Wireless APs allows remote authenticated users to execute code as root. The web-based management interface insufficiently validates user-supplied input in a crafted HTTP request, but Cisco has not disclosed the specific handler or copy operation. Valid administrative credentials and network access to the management interface are required; successful exploitation executes arbitrary code as root.
