AuthFilter Sanitizer Plugin Readme
A plugin for the Openfire Real-time communications server that removes entries for Openfire's authentication filter that are susceptible to abuse (CVE-2023-32315).
Copy the authfiltersanitizer.jar file into the plugins directory of your Openfire installation. The plugin will then be automatically deployed. To upgrade to a new version, copy the new authfiltersanitizer.jar file over the existing file.
The plugin can be configured by using these Openfire system properties:
- plugin.authfiltersanitizer.sanitizetask.periodms (default 10000) - The time (in milliseconds) between successive runs of the task that removes susceptible entries.
- plugin.authfiltersanitizer.sanitizetask.delayms (default 2000) - The time (in milliseconds) between a (re)load of this plugin, and the first run of the task that removes susceptible entries.
- plugin.authfiltersanitizer.sanitizetask.disableSearch (default false) - Controls if, apart from known, hard-coded susceptible entries, the task will dynamically search for other susceptible entries.
Using the Plugin
After the plugin has been installed, the Openfire authentication filter will be periodically cleaned from entries automatically.
