Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Gopkg.in/macaron.v1, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

macaron before 1.3.7 has an open redirect in the static handler. Due to improper request santization, a specifically crafted URL can cause the static file handler to redirect to an attacker chosen URL, allowing for open redirect attacks.
