websocket history garbled text

3iyakebouty | Last updated: Mar 18, 2024 09:10AM UTC

Only websockethistory is garbled. httphistory and others are not garbled. How can I fix the garbled websockethistory? I'm attaching a photo. https://app.box.com/s/7tld09810h7l11wy5feq8z6gt81lu828 https://app.box.com/s/6ypqef8ahtmbp3ckynwdwdnox263u0y3

Hi Is your WebSocket connection sending multi-byte characters or binary data?

How can I display the text without garbling?

Hi Are you able to send a copy of what the message should display? Is the direction of this message Client to Server or Server to Client? Do you have any extensions installed in Burp? If you disable all extensions, does this behavior stay the same?

Hi I tried to copy it, but the garbled text won't let me paste the copy properly. This is a request from the client to the server But in either case, it's garbled.

Thanks for that information. I've tested providing multi-byte characters through a WebSocket connection on one of our Web Academy labs (https://portswigger.net/web-security/websockets/lab-manipulating-messages-to-exploit-vulnerabilities), and it is successfully displayed in the WebSockets message editor. Could you try this out and see if this displays correctly for you? If you toggle the "Show non-printable characters" option, are there any byte characters displayed?

Thanks for the offer. The lab you provided shows multibyte just fine, so it may be in binary format. Can't I get it to display correctly if it's in binary format?
