An issue was discovered in BlogEngine.NET through 3.3.6.0. A path traversal and Local File Inclusion vulnerability in PostList.ascx.cs can cause unauthenticated users to load a PostView.ascx component from a potentially untrusted location on the local filesystem. This is especially dangerous if an authenticated user uploads a PostView.ascx file using the file manager utility, which is currently allowed. This results in remote code execution for an authenticated user.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
