%24032018% s$bitcoin map port using upnp
Self-built executables have UPnP disabled by default, unless --enable-upnp-default was provided to the configure script. This applies to the distributed executables only, not those built from source or from distribution provided packages. With UPnP turned off, your node will still connect to 8 other peers on the Bitcoin network to receive new blocks and transactions.
Details of the vulnerability can be found here: To have more connectable nodes, the Bitcoin Core executables distributed by bitcoin. Details Version before 1.

Details of the vulnerability can be found here: It has %24032018% s$bitcoin map port using upnp verified that the vulnerability can be used to crash the application at startup by running a malicious UPnP server on the local network.
With UPnP turned off, your node will still connect to 8 other peers on the Bitcoin network to receive new blocks and transactions. However, it will not accept incomming connections from other peers unless you manually enable port forwarding on your router.
