Detailed vulnerability description
The vulnerability allows a remote user to read or write files outside the intended sessions directory.
The vulnerability exists due to path traversal in transcript file operations when processing a crafted sessionId or sessionFile path. A remote user can supply a specially crafted sessionId or sessionFile value to read or write files outside the intended sessions directory.
By default the gateway binds to loopback; configurations that expose the gateway widen the attack surface.
