Detailsinfo

A vulnerability was found in AUTOMATIC1111 stable-diffusion-webui up to 1.8.0. It has been declared as critical. This vulnerability affects the function save_config_state of the component Backup/Restore. The manipulation of the argument config_save_name with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

stable-diffusion-webui is a web interface for Stable Diffusion, implemented using Gradio library. Stable-diffusion-webui 1.7.0 is vulnerable to a limited file write affecting Windows systems. The create_ui method (Backup/Restore tab) in modules/ui_extensions.py takes user input into the config_save_name variable on line 653. This user input is later used in the save_config_state method and used to create a file path on line 65, which is afterwards opened for writing on line 67, which leads to a limited file write exploitable on Windows systems. This issue may lead to limited file write. It allows for writing json files anywhere on the server where the web server has access.
