CERT Vulnerability Note VU#636397: IP-in-IP protocol routes arbitrary traffic by default
by Chris KE2A 02 Jun '20

02 Jun '20

Reference: https://kb.cert.org/vuls/id/636397 OVERVIEW IP Encapsulation within IP (RFC2003 IP-in-IP) can be abused by an unauthenticated attacker to unexpectedly route arbitrary network traffic through a vulnerable device. Description IP-in-IP encapsulation is a tunneling protocol specified in RFC 2003 that allows for IP packets to be encapsulated inside another IP packets. This is very similar to IP GRE VPNs and IPSEC VPNs in tunnel mode, except in the case of IP-in-IP, the traffic is unencrypted at all times. As specified, the protocol unwraps the inner IP packet and forwards this packet through IP routing tables, potentially providing unexpected access to network paths available to the vulnerable device. An IP-in-IP device is considered to be vulnerable if it accepts IP-in-IP packets from any source to any destination without explicit configuration between the specified source and destination IP addresses. This unexpected Data Processing Error (CWE-19) by a vulnerable device can be abused to perform reflective DDoS and in certain scenarios used to bypass network access control lists. Because the forwarded network packet may not be inspected or verified by vulnerable devices, there are possibly other unexpected behaviors that can be abused by an attacker on the target device or the target device's network environment. IMPACT An unauthenticated attacker can route network traffic through a vulnerable device, which may lead to reflective DDoS, information leak and bypass of network access controls. -- 73, Chris KE2A

Mikrotik help needed
by Ian Redden 29 May '20

29 May '20

Hi All; When trying to connect, the IPIP tunnel on my Mikrotik box is flapping. I am using Mikrotik OS 6.46.6. It connects, shows as registered/running, but after a random period of time, the link goes down. Eventually it reconnects and the entire process starts over again. While connected however, I am able to see the RIP routes. Configuration: /interface ipip add allow-fast-path=no local-address=24.xx1.xx4.44 name=ucsd-gw remote-address=169.228.34.84 Any ideas? Speed Test: https://cogeco-on.speedtestcustom.com/result/baacd8c0-a027-11ea-8085-870a92… Ian / VA3IAN

WWconvers Hub_NA
by Charles J. Hargrove 21 May '20

Looking to add another dimension to your BBS? Consider offering a chatroom to your users. There are several groups that meet worldwide on various channels, some channels are used locally for events/nets/emcomm and there are some that act as tech support for ham radio software programs. Here in NYC we use 14736 every Monday night as an alternate way to check-in to our weekly emcomm net (especially when encountering jammers). There is even a growing movement to use state or country-based channel numbers that reflect their 44net assignments like 4468 in NY, 4440 in UT, etc. Various packet bbs packages have chat capability built-in. I know of at least one station looking to incorporate it into FBB, but I have no information on that system. Connection to Hub_NA is easy. Use 44.68.41.2 (gw.n2nov.ampr.org). We currently have stations across the USA and Canada connected to Hub_NA. Come join us, ask questions and share your tips/tricks/ideas! -- Charles J.

Some config error in ampraddr
by Rob Janssen 20 May '20

20 May '20

Since today I get error reply mails from amprgw-adm-owner(a)caida.org on the mail I send to ampraddr(a)gw.ampr.org for DNS updates, which indicate that my mail is somehow forwarded to a mailing list at caida where I am not a member, and thus not allowed to mail: You have tried to post to a list you are not subscribed to. Only members are allowed to post to this list. It appears that the update itself is correctly processed, I get the confirmation mail, but also an error message. Anyone knows what is going on there?

Routing from and to the internet
by Elias Basse 10 May '20

10 May '20

I have just completed setup on a ubiquiti router and am wanting to configure a host for some digital radio services behind the router but wish to use the 44 addresses out to the public internet to allow hotspots and repeaters to connect. Is anyone familiar with setting this up? From the server I am able to reach the internet but it is going out through an address from the isp rather than the 44 address. I used the ampr-ripd script from the wiki and can ping other 44 addresses. Hopefully this is possible, I have had my office allow use of some server and network hardware for ham radio. Best Regards Elias Kd5jfe Sent from my iPhone

There is no need to move those addresses, they are not in the block that has been sold. Since a month or two we are routing 44.192.0.0/10 to internet (amazon) but this still causes issues as over 4000 systems in the 44.224.0.0/15 block have not yet been renumbered. (I get occasional complaints about systems no longer being reachable) Rob
