Miggo AIRoot Cause AnalysisThe analysis was conducted without a specific patch, by inspecting the current state of the casdoor/casdoor repository and making inferences based on the vulnerability description. The vulnerability is a path traversal in the Local File System storage provider. The investigation started by identifying the code responsible for this functionality, which was found in storage/local_file_system.go. The Put method in this file is responsible for writing files. The current implementation uses a GetFullPath function to sanitize the path, which suggests that this sanitization was missing in vulnerable versions. This makes storage.LocalFileSystemProvider.Put the primary vulnerable function. Additionally, the object/storage.go file contains two functions for uploading files: uploadFile and UploadFileSafe. The UploadFileSafe function contains an explicit check for path traversal sequences. This indicates that uploadFile is likely the original, unsafe function that was called in the vulnerable workflow. Therefore, object.uploadFile is also identified as a vulnerable function as it processes the malicious input and passes it down to the storage provider.
