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 Github.com/h44z/wg portal, 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

### Summary An Open Redirect vulnerability exists in the OAuth authentication flow that allows attackers to redirect users to external malicious websites after authentication. The vulnerability is caused by insufficient validation of the return parameter in the OAuth login initialization endpoint. ### Patches The problem was fixed in the latest release, v2.1.2. The [docker images](https://hub.docker.com/r/wgportal/wg-portal) for the tag 'latest' built from the master branch also include the fix.
