The install wizard in DotNetNuke 4.0 through 5.1.4 does not prevent anonymous users from accessing functionality related to determination of the need for an upgrade, which allows remote attackers to access version information and possibly other sensitive information.

Security readout for executives and security teams

CVE-2009-4109 is an information disclosure issue in the DotNetNuke install wizard. In versions 4.0 through 5.1.4, anonymous remote users may access upgrade-check functionality and obtain version information, and possibly other sensitive details. This mainly increases reconnaissance risk against legacy DotNetNuke sites. Exposure is most likely on legacy DotNetNuke 4.0 through 5.1.4 deployments where install or upgrade wizard functionality remains reachable by anonymous internet users. Treat as a legacy exposure cleanup item. It is unlikely to be an emergency by itself, but exposed version data can help attackers target older DotNetNuke systems with other vulnerabilities. Mitigation focus: Identify any DotNetNuke deployments in the affected 4.0 through 5.1.4 range.; Review DotNetNuke Security Bulletin No. 30 for vendor-prescribed remediation.; Upgrade or reconfigure affected systems according to vendor guidance..
