• Bug report: BinkP CRAM challenges

    From Rob Swindell to All on Friday, March 09, 2018 11:36:55
    I'm not sure if this echo is still active (doesn't appear to be), but here goes anyway:

    During the development of a new BinkP mailer (http://wiki.synchro.net/module:binkit) we found an incompatibility with Internet Rex 2.29 Win32, due to a BinkP spec violation:

    When IRex is making an outbound connection to a BinkP link using CRAM-MD5 auth, if the CRAM challenge (sent by the remote) is greater in length than 16 bytes (32 hex chars), then IRex fails to compute the CRAM response (MD5-HMAC) correctly. The specification (FTS-1027) states:

    "Size and contents of challenge data are implementation-dependent,
    but it SHOULD be no smaller than 8 bytes and no bigger than 64
    bytes."

    Yet IRex appears to only support 16 byte challenges (which happens to be what BinkD sends, always).

    I'm not sure if this echo is still active (doesn't appear to be), but anyway:

    The echo is still here, but I do not know if Charles still follows the echo or not. Just in case, I forwarded a copy of your message to him to see what he can do, if ANYTHING, about that.

    Do you see this issue when someone connects to a binkit system using version 2.31 of Internet Rex?

    Honestly, I don't know:

    1. No one is connecting to *my* mailer using Irex, this was was determined through debugging a sysops issues with his links. The only version of IRex in use during this problem report was 2.29.

    2. We've since changed BinkIT to only send a 16-byte CRAM challenge to resolve the incompatibility, so unless we find a guinea pig running versions of IRex *newer* than 2.29 and willing to experiment with a link running BinkIT, we'll never know.

    Hi Rob,

    Didnt realise there were newer versions of Irex (2.29) - if there is, happy
    to upgrade and test if useful.

    Any version of IRex newer than 2.29 is a beta version, not a release. 2.31 is widely available, and there are a few of Charles' beta sites running a 2.67 beta.

    Be advised there is NOT a v2.67 of iRex, Beta or otherwise, unless someone managed to patch one for whatever reason, obviously subject to malware!

    If anyone needs v2.29 (last production release) or 2.31 (last Beta, considered stable) feel free to surf to:

    http://cmech.dynip.com/filebase.bbs/IREX/ for v2.29
    or, http://cmech.dynip.com/filebase.bbs/IREX/Beta/ for v2.31

    That is good news! Is there still a beta team and any activity? I can think of a lot of folks who would like to see a new version of IRex released.
