Subject: [EXTERNAL] Looking for missing documentation (MS-KILE?) for CVE-2024-21427, CVE-2024-20674 and PAC signature changes
Kia Ora Dochelp,
Recently we have seen CVE-2024-21427 and CVE-2024-20674 issued.
The first CVE-2024-21427, we know what the details are from our report, but we don't have details of the protocol change from the MS side, so would like the full details in case there were protocol changes we didn't anticipate.
We don't have any details of the protocol changes for CVE-2024-20674, and as it is marked Critical we would like to ensure we don't have a similar issue or can follow any protocol changes made for interoperability.
Finally, we have noticed in November (or earlier) that the Server signature in the Kerberos PAC is no longer RC4_HMAC, even with RC4 tickets. This makes a lot of sense, but I don't see any documentation and I would like to update our implementation to match.
We would greatly appreciate any information that is available on these recent Kerberos protocol changes.
Thanks,
Andrew Bartlett
