You should not do this, but set your repo to use vault.centos.org e.g. 
http://vault.centos.org/7.5.1804/updates/x86_64/

Then do yum updates, then set it back to what it was before.

The likelyhood is that your software supplier, and possibly yourself, do 
not actually understand the Centos Reaase Scheme.
