Impact
Implementations using this library with directory browsing enabled may be susceptible to Cross Site Scripting (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.
