#10028 closed defect (fixed)

Linux IGD leaves UPnP port accessible from outside by default

Reported by: zigo@… Owned by: developers
Priority: highest Milestone: Chaos Calmer 15.05
Component: packages Version: Backfire 10.03
Keywords: Cc:



After I heard about some Linksys routers leaving the UPnP port opened by default, I wanted to check my OpenWRT config. And a netstat -anple, and a test with nmap from outside showed that the Linux IGD UPnP daemon does the same: the port 49152 is opened by default to the outside, which really, shouldn't be the case, since this is a grave security issue.

While you have Linux IGD installed, is there any chance you could test for a memory leak (Re: Ticket #7444)?

P.S. I'm running Backfire with miniupnpd - 1.5.20110302-6 and closing ports is not an issue as long as the client application supports it.

See ticket #8934 where I confirmed this issue is not present in libupnp - 1.6.8-1 from trunk snapshots.
