When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly \"short-cut\" the host handshake. When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check."},{"lang":"es","value":"curl  versiones 7.63.0 hasta 7.75.0 incluyéndola, incluye una vulnerabilidad que permite que un proxy HTTPS malicioso acceda a una conexión MITM debido al manejo inapropiado de los tickets de sesión de TLS versión 1.3.&#xa0;Cuando se usa un proxy HTTPS y TLS 1.3, libcurl puede confundir los tickets de sesión que llegan del proxy HTTPS pero funciona como si llegaran del servidor remoto y luego \"short-cut\" incorrectamente el protocolo de enlace del host.&#xa0;Al confundir los tickets, un proxy HTTPS puede engañar a libcurl para que utilice la reanudación del ticket de sesión incorrecta para el host y, por lo tanto, omitir la verificación del certificado TLS del servidor y hacer que un ataque MITM sea posible de realizar sin ser detectado.&#xa0;Tome en cuenta que dicho proxy HTTPS malicioso debe proporcionar un certificado que curl aceptará para el servidor MITMed para que funcione un ataque, a menos que se le haya dicho a
