CVE-2021-32066 – ruby: StartTLS stripping vulnerability in Net::IMAP
https://notcve.org/view.php?id=CVE-2021-32066
An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack." Se ha detectado un problema en Ruby versiones hasta 2.6.7, versiones 2.7.x hasta 2.7.3, y versiones 3.x hasta 3.0.1. Net::IMAP no lanza una excepción cuando StartTLS falla con una respuesta desconocida, lo que podría permitir a atacantes tipo man-in-the-middle omitir las protecciones TLS, al aprovechar una posición de red entre el cliente y el registro para bloquear el comando StartTLS, también se conoce como "StartTLS stripping attack" Ruby's Net::IMAP module did not raise an exception when receiving an unexpected response to the STARTTLS command and the connection was not upgraded to use TLS. A man-in-the-middle attacker could use this flaw to prevent Ruby applications using Net::IMAP to enable TLS encryption for a connection to an IMAP server and subsequently eavesdrop on or modify data sent over the plain text connection. • https://github.com/ruby/ruby/commit/a21a3b7d23704a01d34bd79d09dc37897e00922a https://hackerone.com/reports/1178562 https://lists.debian.org/debian-lts-announce/2021/10/msg00009.html https://lists.debian.org/debian-lts-announce/2023/04/msg00033.html https://security.gentoo.org/glsa/202401-27 https://security.netapp.com/advisory/ntap-20210902-0004 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.ruby-lang.org/en/news/2021/07/07/starttls-stripping-in-net-imap https://acces • CWE-319: Cleartext Transmission of Sensitive Information CWE-755: Improper Handling of Exceptional Conditions •
