CVE-2022-41905
Cross Site Scripting vulnerability in wsgidav when directory browsing is enabled
Impact
### Impact Implementations using this library with directory browsing enabled may be susceptible to [Cross Site Scripting (XSS)](https://owasp.org/www-community/attacks/xss/) attacks. ### Patches Users can upgrade to v4.1.0 ### Workarounds Set `dir_browser.enable = False` in the configuration. For instance, when using a Python dictionary to configure the library: ``` config = { # your normal configuration "dir_browser": { "enable": False }, } app = WsgiDAVApp(config) ``` ### For more information Note that an attacker cannot exploit this vulnerability, by simply uploading a file or folder with a manipulated file name. However if the WsgiDAV library is used in a scenario where untrusted data is displayed in the directory browser's user interface (e.g. 'realm' or user name, ...) XSS may happen.
