CVE-2022-2880 : What You Need to Know

This article provides an in-depth look at CVE-2022-2880, detailing the vulnerability, its impact, and mitigation strategies.

Understanding CVE-2022-2880

CVE-2022-2880 involves the incorrect sanitization of forwarded query parameters in net/http/httputil, potentially leading to query parameter smuggling.

What is CVE-2022-2880?

Requests forwarded by ReverseProxy in Go include raw query parameters from inbound requests, allowing query parameter smuggling when proxies forward unparsable values. The vulnerability has been addressed by sanitizing query parameters.

The Impact of CVE-2022-2880

The vulnerability could be exploited to manipulate query parameters, posing a risk of query parameter smuggling when Go proxies forward unparsable values, impacting the integrity of data transmission.
