Red Hat Security Advisory: mod_auth_openidc:2.3 security and bug fix update

Severity

Moderate

Scope

2 vulnerabilities in this advisory, including CVE-2019-20479.

CVE-2019-20479

An open redirect flaw was discovered in mod_auth_openidc where it handles logout redirection. The module does not correctly validate the URL, allowing a URL with slash and backslash at the beginning to bypass the protection checks. A victim user may be tricked into visiting a trusted vulnerable web site, which would redirect him to another, possibly malicious, URL.
