Descripción

*** Pendiente de traducción *** LWP::UserAgent versions before 6.83 for Perl leak Authorization and Proxy-Authorization headers on cross-origin redirects.<br /> <br /> On a 3xx response, the redirect handler strips only Host and Cookie before issuing the follow-up request. Caller-supplied Authorization and Proxy-Authorization headers are sent unchanged to the redirect target, including across scheme, host, or port changes.<br /> <br /> A redirect to an attacker controlled host therefore discloses the caller&amp;#39;s credentials to that host.
