DotNetNuke before 4.8.2, during installation or upgrade, does not warn the administrator when the default (1) ValidationKey and (2) DecryptionKey values cannot be modified in the web.config file, which allows remote attackers to bypass intended access restrictions by using the default keys.

Security readout for executives and security teams

DotNetNuke before 4.8.2 could leave default cryptographic keys in web.config during install or upgrade without clearly warning administrators. If those keys remain predictable, a remote attacker could bypass intended access restrictions. This is mainly a legacy DotNetNuke exposure and depends on whether the default keys were left in place. Internet-facing legacy DotNetNuke sites running versions before 4.8.2 are the primary concern, especially systems installed or upgraded with unchanged default web.config machineKey values. Treat this as a priority legacy exposure check, not a current mass-exploitation alert. If DotNetNuke remains externally reachable, validate version and key configuration promptly because predictable keys can undermine access restrictions. Mitigation focus: Upgrade DotNetNuke versions before 4.8.2 to 4.8.2 or later vendor-supported releases.; Review DotNetNuke Security Bulletin no.12 for vendor-specific remediation guidance.; Ensure web.config ValidationKey and DecryptionKey values are unique and not defaults..
