Broken Extensions preferences since burpsuite_pro_v2023.1.2

Kacper | Last updated: Feb 23, 2023 09:23AM UTC

Hello, Since burpsuite_pro_v2023.1.2 the extensions cannot load their previous preferences. The extensions load/save the preferences by the following APIs: - loadExtensionSetting(name) - saveExtensionSetting(name, value) docs: https://portswigger.net/burp/extender/api/burp/iburpextendercallbacks.html#loadExtensionSetting-java.lang.String- The preferences files are saved on Linux ~/.java/.userPrefs/burp/extensions/<ext>/prefs.xml by default. Since version 2023.1.2 the settings are loaded/saved with the following name: "string_<setting_name>", which makes it impossible for any existing extensions to read the previous settings. Snippet from one of my prefs.xml: <entry key="string_window-state" value="6"/> <entry key="string_windowHeight" value="1459"/> <entry key="string_windowWidth" value="2560"/> <entry key="window-state" value="6"/> <entry key="windowHeight" value="1459"/> <entry key="windowWidth" value="2560"/> Now, the prefs.xml contains both the new settings (string_<name>) and the previous ones. I tried the latest early adopter version (burpsuite_pro_v2023.2.1.jar) and the bug is still not fixed. It affects all extensions I am using.

Do you have any ETA when the fix will be released? I still have to use Burp 2022.12.7, as the extensions I use need to read/write the preferences correctly.

Hi Unfortunately, we do not currently have an ETA. We are planning on resolving this issue but cannot provide a timeframe. Are you able to recreate your preferences in the newer version of Burp, or do you have specific items saved that need to be persisted?
