In the Qualys Knowledge base, the access vector is shown as Network but as far my understanding goes, you need to be in the same network to carry out these attacks, Can we say that the access vector will be 'Adjacent Network' for this case?
Yes. In order to exploit the vulnerabilities you need to see the data over the network.
The access vector that you see in the Knowledgebase is based on CVSS v2 which does not have a value for "Adjacent Network". CVSS v3 has the value "Adjacent Network".
In the near future, we plan to provide CVSS v3 data but until then you will see CVSS v2 data under the Knowledgebase.
