Description

A flaw was found in Perl's CPAN, which doesn't check TLS certificates when downloading content. This happens due to verify_SSL missing when suing the HTTP::Tiny library during the connection. This may allow an attacker to inject into the network path and perform a Man-In-The-Middle attack, causing confidentiality or integrity issues.
