CVE-2019-3877 – mod_auth_mellon: open redirect in logout url when using URLs with backslashes
https://notcve.org/view.php?id=CVE-2019-3877
A vulnerability was found in mod_auth_mellon before v0.14.2. An open redirect in the logout URL allows requests with backslashes to pass through by assuming that it is a relative URL, while the browsers silently convert backslash characters into forward slashes treating them as an absolute URL. This mismatch allows an attacker to bypass the redirect URL validation logic in apr_uri_parse function. Se ha detectado una vulnerabilidad en mod_auth_mellon, en anteriores a la v0.14.2. Una redirección abierta en la URL de cierre de sesión permite que las peticiones con barras invertidas pasen asumiendo que es una URL relativa, mientras que los navegadores convierten silenciosamente los caracteres de barra invertida en barras, tratándolos como una URL absoluta. • https://access.redhat.com/errata/RHSA-2019:0766 https://access.redhat.com/errata/RHSA-2019:3421 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3877 https://github.com/Uninett/mod_auth_mellon/commit/62041428a32de402e0be6ba45fe12df6a83bedb8 https://github.com/Uninett/mod_auth_mellon/issues/35 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CNW5YMC5TLWVWNJEY6AIWNSNPRAMWPQJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/X7 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVE-2019-3878 – mod_auth_mellon: authentication bypass in ECP flow
https://notcve.org/view.php?id=CVE-2019-3878
A vulnerability was found in mod_auth_mellon before v0.14.2. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication. Se ha detectado una vulnerabilidad en mod_auth_mellon, en versiones anteriores a la v0.14.2. Si Apache está configurado como proxy inverso y mod_auth_mellon está configurado para que solo deje acceder a los usuarios autenticados (con la directiva "require valid-user"), la adición de cabeceras HTTP especiales que se suelen emplear para iniciar el SAML ECP especial (no basado en el navegador) puede emplearse para omitir la autenticación. A vulnerability was found in mod_auth_mellon. • https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0746 https://access.redhat.com/errata/RHSA-2019:0766 https://access.redhat.com/errata/RHSA-2019:0985 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3878 https://github.com/Uninett/mod_auth_mellon/pull/196 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CNW5YMC5TLWVWNJEY6AIWNSNPRAMWPQJ https://lists.fedoraproject.org/archives/list/package-announce%40lists. • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
