Fixed issue, it was blocking my hosting problem.
I explain, according to my technicians:
The Cibo of Xibo 1.8.10 is taking the identification string of IE6, and is using it. This chain is the identification of old web clients (internet explorer 6), it is old, without maintenance and with a rich history of vulnerabilities. If a user uses it, it is possible that he has it hacked or with Trojans.
Therefore, this identification chain is not related to the greater or lesser security of the CMS. That is, because it uses that identifying chain, the CMS is not insecure. It’s just a text string.
For this reason, a few days ago I was given a security protection that blocks the accesses that use this identification string, since my CMS uses it for access.
From here comes the problem when I wanted to upload a client to the Xibo CMS, access was blocked. Now I have a different security configuration, to avoid blocking problems of this type.
My question is why do you use this IE6 text string?
Thank you so much for everything
