How the CVE Works
DNN.PLATFORM fails to properly validate client IP addresses during authentication, allowing attackers to bypass IP-based access controls. A crafted HTTP request with spoofed headers (e.g., X-Forwarded-For) can trick the system into accepting login attempts from unauthorized IPs. The vulnerability stems from improper parsing of proxy-forwarded headers, enabling attackers to manipulate their perceived origin IP. This flaw affects versions prior to 10.0.1, where the IP filter logic did not enforce strict validation.
