Description Jeff Kowalczyk 2022-10-04 21:18:20 UTC

Requests forwarded by ReverseProxy included the raw query parameters from the inbound request, including unparseable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy forwards a parameter with an unparseable value.

ReverseProxy will now sanitize the query parameters in the forwarded query when the outbound request's Form field is set after the ReverseProxy.Director function returns, indicating that the proxy has parsed the query parameters. Proxies which do not parse query parameters continue to forward the original query parameters unchanged.

Thanks to Gal Goldstein (Security Researcher, Oxeye) and Daniel Abeles (Head of Research, Oxeye) for reporting this issue.

This is CVE-2022-2880 and Go issue https://go.dev/issue/54663.
