CVE-2021-39191 (GCVE-0-2021-39191)

Vulnerability from cvelistv5 – Published: 2021-09-03 00:00 – Updated: 2024-08-04 01:58

Title

URL Redirection to Untrusted Site ('Open Redirect') in mod_auth_openidc

Summary

mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions prior to 2.4.9.4, the 3rd-party init SSO functionality of mod_auth_openidc was reported to be vulnerable to an open redirect attack by supplying a crafted URL in the `target_link_uri` parameter. A patch in version 2.4.9.4 made it so that the `OIDCRedirectURLsAllowed` setting must be applied to the `target_link_uri` parameter. There are no known workarounds aside from upgrading to a patched version.

Severity
