Описание
urllib3 before 1.24.2 does not remove the authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the authorization header to be exposed to unintended hosts or transmitted in cleartext. NOTE: this issue exists because of an incomplete fix for CVE-2018-20060 (which was case-sensitive).
A flaw was found in the urllib3 package. Affected versions of this package are vulnerable to information exposure through sent data when the authorization HTTP header is not removed during a cross-origin redirect. An attacker can expose credentials in the authorization header to unintended hosts or transmit them in clear text by exploiting the incomplete fix for CVE-2018-20060.
Отчет
This is only exploitable if a redirect differs in host, port, or scheme. Due to the credential exposure in the authorization header, the confidentiality is highly impacted, but there is no proof that the integrity is affected in any way.
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.
