# CVE-2019-10097: Apache HTTP Server vulnerability | CubePath

## Description

In Apache HTTP Server 2.4.32-2.4.39, when mod\_remoteip was configured to use a trusted intermediary proxy server using the "PROXY" protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients.
