MWG+NTLM+CVE-2020-1472

[mkutrieba]

Hello all,

here latest information from engineering:
This is addressed for Version 10.1 with bug ID WP-3024.
10.1 will be released in Q1 matching to Microsoft's Deadline in February.

Engineering also considers to implement fix in 10.0.1 (Nov) or 10.0.2 (Dec or Jan) if possible, so no guarantee for that.

Until then i guess we can move to Kerberos anyways? That should mitigate the issue?

Yes correct.

What about use LDAP authentication, will mitigate this issue or not?

[mkutrieba]

Hello,

yes, so you can use Kerberos authentication and/or LDAP for group lookup for example. Only NTLM connections between MWG and AD are affected here.

Marcel - when you say this issue will be addressed with the release of Version 10.1 ( or 10.0.1 (Nov) or 10.0.2 (Dec or Jan)) - does that mean we will need to upgrade Web Gateway appliances from 8.2.x to 10.1?

Hello,

had quick chat with colleague from engineering, he informed that this will also be backported. As 7.8.2 will be EOL at this time, I guess backport will be for versions 8.2.x, and 9.2.x.

Exact versions and timeline is not yet fix/known. Will try to keep this post updated.

Using Kerberos might be a good idea. But an remaining issue is the login to the Web-UI which is still using NTLM and will break when I force secure authentication.
