Summary

A time/boolean SQL Injection is present in the following resource /api/applicationResources via the following parameter packageID

Details

As it can be seen here, while building the SQL Query the fmt.Sprintf function is used to build the query string without the input having first been subjected to any validation.

PoC

The following command should be able to trigger a basic version of the behavior:
curl -i -s -k -X $'GET' \ -H $'Host: kubeclarity.test' \ $'https://kubeclarity.test/api/applicationResources?page=1&pageSize=50&sortKey=vulnerabilities&sortDir=DESC&packageID=c89973a6-4e7f-50b5-afe2-6bf6f4d3da0a\'HTTP/2'

Impact

While using the Helm chart, the impact of this vulnerability is limited since it allows read access only to the kuberclarity database, to which access is already given as far as I understand to regular users anyway.
On the other hand, if Kuberclarity is deployed in a less secure way, this might allow access to more data then allowed or expected (beyond the limits of the KuberClarity database). The vulnerable line was introduced as part of the initial commit of Kubeclarity, so all versions up until the latest (2.23.1) are assumed vulnerable.
