tlsenum
tlsenum tlsenum is a command-line TLS enumeration tool that attempts to enumerate what TLS cipher suites a server supports and list them in order of priority. It works by sending out sending out TLS ClientHello messages and parsing the ServerHello responses from the server. tlsenum assumes that t...
Astra Linux – Vulnerability in mbedtls
A issue was discovered in Mbed TLS 3.5.1. There is a persistent handshake denial if a client sends a TLS 1.3 ClientHello without extensions...
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...
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-2026-79896
Fortra BoKS Manager is vulnerable to an out-of-bounds read in the custom TLS ClientHello parser utilized by boks_portmux . A remote unauthenticated attacker can exploit this by submitting a malformed ClientHello to terminate the boks_portmux daemon. While the daemon typically restarts automatical...

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...
