Burp Suite Proxy - Intercept domain name with underscore

Niv | Last updated: Jan 06, 2023 07:12AM UTC

Hello PortSwigger team, In a recent penetration test project, I encountered an issue with intercepting HTTP traffic since the new version of Burp Suite doesn't know to handle domain names with underscores. After some trial and error, I figured out that using an old version, burpsuite_pro_v2022.11.4.jar, with jdk-11.0.17+8 would let me intercept requests to a non-RFC-compliant domain name. Best regards, Niv
