Vulnerability Spotlight: Denial-of-service vulnerabilities in Micrium uc-HTTP’s HTTP server

Summary: Cisco Talos discovered two denial-of-service vulnerabilities in Micrium uC-HTTP's HTTP server, tracked as TALOS-2020-1193/CVE-2020-13582 (unchecked return value) and TALOS-2020-1194/CVE-2020-13583 (null pointer dereference), both triggered by specially crafted HTTP requests. Talos confirmed the flaws affect uC-HTTP version 3.01.00, an HTTP server built for embedded systems running the µC/OS II or µC/OS III RTOS kernels, and worked with Micrium under its coordinated disclosure policy to make an update available.

What you should know: These flaws sit in an embedded HTTP server on RTOS-based devices, where a single crafted request can take the service down and the update depends on Micrium and the device makers shipping it - not on your patching cycle.
