Funciona enviando mensajes TLS ClientHello y analizando las respuestas ServerHello del servidor. tlsenum asume que el...

CVE-2026-79896

Fortra BoKS Manager contains an out-of-bounds read vulnerability in the custom TLS ClientHello parser used by boksportmux. A remote unauthenticated attacker can submit a malformed ClientHello and terminate boksportmux. Although the daemon is normally restarted automatically, repeated requests can...

cve-2021-3449

CVE-2021-3449 OpenSSL This issue was reported to OpenSSL on 17th March 2021 by Nokia. The fix was developed by Peter Kästle and Samuel Sapalski from Nokia. Mitigation The only known fix is to update libssl1.1. Even though some applications use hardened TLS configurations by default that disable T...

CVE-2026-102712

On the first DTLS ClientHello, the parser copies a device-claimed sessionid length and validates the ciphersuite-list length against the total record length instead of the remaining bytes. An unauthenticated peer drives an OOB source read of up to 255 bytes, and those bytes are echoed verbatim in...

io.netty/netty-handler: Netty: SNI Routing Bypass via Fragmented TLS ClientHello Causing Fallback to Default SslContext

A flaw was found in Netty, an asynchronous, event-driven network application framework. An unauthenticated remote attacker can exploit fragmented Transport Layer Security TLS ClientHello messages to bypass the Server Name Indication SNI routing mechanism. This forces a fallback to a less secure...
