Name of the Vulnerable Software and Affected Versions: DNN (formerly DotNetNuke) versions 7.0.0 through 10.0.0

Description: The issue allows a specially crafted request or proxy to bypass the design of DNN Login IP Filters, enabling login attempts from IP addresses not in the allow list. This has been patched in version 10.0.1.

Recommendations: For versions 7.0.0 through 10.0.0, update to version 10.0.1 to resolve the issue. As a temporary workaround, consider restricting access to the DNN Login IP Filters to minimize the risk of exploitation.
