Hello
I use automatic translation because I am not good at English. sorry.
I took NVD 's CVE list (Json Feed) into Splunk.
That's index="testIndex" product_name = "openssl" "version_data" = "1.6.0" Searching with
There is no "1.6.0" in the version of openssl
I want to link product with version but it does not work as expected.
I can't get spath or mvexpand to extract the nested arrays properly
Someone help me.

Here is another solution, but this one does not need mvzip, split or mvindex:
|makeresults |eval json=" {
\"cve\" : {

\"vendor\" : {
\"vendor_data\" : [ {
\"vendor_name\" : \"openssl\",
\"product\" : {
\"product_data\" : [ {
\"product_name\" : \"openssl\",
\"version\" : {
\"version_data\" : [ {
\"version_value\" : \"*\"
}, {
\"version_value\" : \"0.9.8\"
}, {
\"version_value\" : \"0.9.8a\"
}, {
\"version_value\" : \"0.9.8b\"
}, {
\"version_value\" : \"0.9.8c\"
}, {
\"version_value\" : \"0.9.8d\"
}, {
\"version_value\" : \"0.9.8f\"
}, {
\"version_value\" : \"0.9.8g\"
} ]
}
} ]
}
}, {

Hi,
Map JSON logs to _json sourcetype.
In the props.conf file create stanza like below.
[_json]
KV_MODE= json
It will extract fields. So don't need to search nested json files. Just search fields you require.
