Message-ID: <20230418154630.eoheygqyom3c7ovw@stig.io> Date: Tue, 18 Apr 2023 17:46:30 +0200 From: Stig Palmquist <stig@...g.io> To: oss-security@...ts.openwall.com Cc: sjn@....org Subject: Perl's HTTP::Tiny has insecure TLS cert default, affecting CPAN.pm and other modules HTTP::Tiny v0.082, a Perl core module since v5.13.9 and available standalone on CPAN, does not verify TLS certs by default. Users must opt-in with the verify_SSL=>1 flag to verify certs when using HTTPS. We grepped trough CPAN to find distributions using HTTP::Tiny that didn't specify cert verification behaviour, possibly exposing users to mitm attacks. Here are some examples with patches: - CPAN.pm v2.34 downloads and executes code from https://cpan.org without verifying server certs. Fixed in v2.35-TRIAL. https://github.com/andk/cpanpm/commit/9c98370287f4e709924aee7c58ef21c85289a7f0 - GitLab::API::v4 v0.26 exposes API secrets to a network attacker. https://github.com/bluefeet/GitLab-API-v4/pull/57 - Finance::Robinhood v0.21 is maybe exposing API secrets and financial information to a network attacker. https://github.com/sanko/Finance-Robinhood/pull/6 - Paws (aws-sdk-perl) v0.44 is maybe exposing API secrets to a network attacker. https://github.com/pplu/aws-sdk-perl/pull/426 - CloudHealth::API v0.01 is maybe exposing API secrets to a network attacker. https://github.com/pplu/cloudhealth-api-perl/pull/2 ... and more. We have generated a list of over 300 potentially affected CPAN distributions.
