CVE-2022-43551

A vulnerability exists in curl <7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. However, the HSTS mechanism could be bypassed if the host name in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Like using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop (U+002E) `.`. Then in a subsequent request, it does not detect the HSTS state and makes a clear text transfer. Because it would store the info IDN encoded but look for it IDN decoded.

Summary
  • (es) Existe una vulnerabilidad en la verificación HSTS de curl &lt;7.87.0 que podría omitirse para engañarlo y seguir usando HTTP. Usando su soporte HSTS, se puede indicar a curl que use HTTPS en lugar de usar un paso HTTP de texto plano inseguro incluso cuando se proporciona HTTP en la URL. Sin embargo, el mecanismo HSTS podría omitirse si el nombre de host en la URL dada utiliza primero caracteres IDN que se reemplazan por sus homólogos ASCII como parte de la conversión de IDN. Como usar el carácter UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) en lugar del punto común ASCII (U+002E) `.`. Luego, en una solicitud posterior, no detecta el estado HSTS y realiza una transferencia de texto plano. Porque almacenaría la información IDN codificada pero la buscaría IDN decodificada.
