Not supporting ÅÄÖ characters in Extensions

Wolfie | Last updated: Dec 10, 2021 08:45AM UTC

Hello! I am not sure if this is a burp issue or a extension creator issue. However, i will still make an attempt in a hopeful fix to my issue! * Specs: Burpsuite v2021.10.3 Windows 10 Pro OS Build 19044.1348 Jython 2.7.2 * What was i Attempting? I was trying to install the Authorize Extension to burpsuite or any python based extention in the matter of fact. When attempting to load this extension into burp (after jython was installed), an error message popps up about UTF-8, giving me the impression it might be an issue with my second name as i have an Å in my second name on the laptop. This making the windows paths having this letter and i guess crashing completely. Issue verified with a coworker that has an Ö in the second name. This coworker could not fire up any Python based extensions either. The people that did not have an Å, Ä or an Ö, in their second name, it worked perfectly smooth! Merry Christmas from Sweden. Santa sends his regards! ========== Error code when attempting to fire up JS Link Finder extension: Traceback (most recent call last): File "<string>", line 1, in <module> UnicodeDecodeError: 'utf-8'
