Descriptions
The TLS stack in Mono before 3.12.1 allows man-in-the-middle attackers to conduct message skipping attacks and consequently impersonate clients by leveraging missing handshake state validation, aka a "SMACK SKIP-TLS" issue.
La pila TLS en Mono en versiones anteriores a la 3.12.1 permite que los atacantes Man-in-the-Middle (MitM) realicen ataques de salto de mensajes y que puedan suplantar clientes aprovechándose de la falta de validación del estado de los "handshakes". Esta vulnerabilidad también se conoce como "SMACK SKIP-TLS".
It was discovered that the Mono TLS implementation was vulnerable to the SKIP-TLS vulnerability. A remote attacker could possibly use this issue to perform client impersonation attacks. It was discovered that the Mono TLS implementation was vulnerable to the FREAK vulnerability. A remote attacker or a man in the middle could possibly use this issue to force the use of insecure ciphersuites. Various other issues were also addressed.
