Nexus Repository 3 - Insufficiently Protected Credentials in Repository Signing Passphrase

Summary

Sonatype Nexus Repository 3 returns the signing passphrase of an APT or YUM repository, through an internal REST endpoint, to a user account that holds only the read privilege for administering that repository. The account does not need the privilege to edit the repository.

Remediation

1. Inventory every Sonatype Nexus Repository 3 deployment, including staging.
2. Upgrade Sonatype Nexus Repository 3 to 3.98.0.
3. Confirm the running version after the upgrade.
