HTTP: EmbedThis GoAhead Web Server File Upload Use After Free
This signature detects attempts to exploit a known vulnerability against EmbedThis GoAhead Web Server. A successful attack can lead to arbitrary code execution.
Extended Description
An exploitable code execution vulnerability exists in the processing of multi-part/form-data requests within the base GoAhead web server application in versions v5.0.1, v.4.1.1 and v3.6.5. A specially crafted HTTP request can lead to a use-after-free condition during the processing of this request that can be used to corrupt heap structures that could lead to full code execution. The request can be unauthenticated in the form of GET or POST requests, and does not require the requested resource to exist on the server.
