Vulnerability Spotlight: Two vulnerabilities in Embed This GoAhead
Summary: A Cisco Talos researcher found two vulnerabilities in EmbedThis's GoAhead Web Server, both triggered when the software processes multi-part/form-data HTTP requests in versions v5.0.1, v4.1.1 and v3.6.5. One is a use-after-free that can corrupt heap structures and lead to full code execution, the other an infinite loop causing denial of service, and both can be reached through unauthenticated GET or POST requests that do not require the requested resource to exist on the server.
What you should know: GoAhead is an embedded web server built into devices, and an unauthenticated request that does not even need a valid resource path is enough to reach either flaw - so any internet-facing device running these versions is exposed before authentication is ever checked.
