Описание

LWP::UserAgent versions before 6.83 for Perl leak Authorization and Proxy-Authorization headers on cross-origin redirects. 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. A redirect to an attacker controlled host therefore discloses the caller's credentials to that host.

A flaw was found in LWP::UserAgent, a component of perl-libwww-perl. This vulnerability allows a remote attacker to obtain a user's credentials by redirecting a request to an attacker-controlled host. When processing a redirect, the LWP::UserAgent fails to properly strip Authorization and Proxy-Authorization headers, leading to their unintended disclosure across different origins.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
