Descriptions
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. Este error de emparejamiento permite que un atacante omita la lógica de validación de URL de redirección en la función apr_uri_parse.
