How to Fix CVE-2020-7010

To remediate this vulnerability, upgrade all affected Github.com/elastic/cloud on k8s dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/elastic/cloud-on-k8s fixed: 1.1.0 
Upgrade github.com/elastic/cloud-on-k8s to 1.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/elastic/cloud-on-k8s

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-7010, inspect your project dependencies for Github.com/elastic/cloud on k8s:

inspect dependencies for github.com/elastic/cloud-on-k8s

Analyze the terminal output to locate any version of Github.com/elastic/cloud on k8s in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-335: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG), where the product uses a pseudo-random number generator (prng) but does not correctly manage seeds. In Github.com/elastic/cloud on k8s, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Elastic Cloud on Kubernetes (ECK) versions prior to 1.1.0 generate passwords using a weak random number generator. If an attacker is able to determine when the current Elastic Stack cluster was deployed they may be able to more easily brute force the Elasticsearch credentials generated by ECK.
