CVE-2007-5770

Las librerias (1) Net::ftptls, (2) Net::telnets, (3) Net::imap, (4) Net::pop, y (5) Net::smtp en Ruby 1.8.5 y 1.8.6 no verifica el campo commonName (CN) en un servidor que valida certificados el nombre de dominio en una respuesta enviada sobre SSL, lo cual hace más facil a los atacantes remotos interceptar transmisiones SSL a través de un ataque de hombre en el medio o suplantando el sitio web, un componente diferente que el CVE-2007-5162.

Chris Clark discovered that Ruby's HTTPS module did not check for commonName mismatches early enough during SSL negotiation. If a remote attacker were able to perform man-in-the-middle attacks, this flaw could be exploited to view sensitive information in HTTPS requests coming from Ruby applications. It was discovered that Ruby's FTPTLS, telnets, and IMAPS modules did not check the commonName when performing SSL certificate checks. If a remote attacker were able to perform man-in-the-middle attacks, this flaw could be exploited to eavesdrop on encrypted communications from Ruby applications using these protocols.
