* JA4: Fix SSL 2 version and remove fictional SSL 1 version along with ↵Daniel Roethlisberger2025-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mis-mapping to s3 (#2684) * JA4: Fix SSL 2 version constant to 0x0002 SSL 2 uses a version field of 0x0002, not 0x0200. This is confirmed not only in the original Netscape spec [1] and RFC draft of the time [2], but also in major implementations such as OpenSSL [3] and Wireshark [4]. An earlier version of the JA4 spec [5] also mistakenly used 0x0200 for SSL 2 and 0x0100 for SSL 1. This was fixed in [6] in August 2024. [1] https://www-archive.mozilla.org/projects/security/pki/nss/ssl/draft02.html [2] https://datatracker.ietf.org/doc/html/draft-hickman-netscape-ssl-00 [3] https://github.com/openssl/openssl/blob/OpenSSL_0_9_6m/ssl/ssl2.h#L66-L71 [4] https://github.com/wireshark/wireshark/blob/release-4.4/epan/dissectors/packet-tls-utils.h#L266-L277 [5] https://github.com/FoxIO-LLC/ja4/blob/main/technical_details/JA4.md#tls-and-dtls-version [6] FoxIO-LLC/ja4#150 * JA4: Remove fictional (and mis-mapped to "s3") SSL 1 SSL 1 was never actually deployed, the design was iterated upon to become SSL 2 before it was released by Netscape [1] [2] [3] [4]. I don't think it's public knowledge what the version field for SSL 1 would have looked like, or if it even was two bytes large or at the same offset on the wire; given that SSL 2 used 0x0002 it seems more likely to have been 0x0001 than 0x0100. Version field 0x0100, that is currently misattributed to SSL 1, was used by an early pre-RFC4347 implementation of DTLS in OpenSSL before 0.9.8f [5], when OpenSSL switched to the version field specified by RFC4347. This use of 0x0100 is also reflected in Wireshark's TLS dissector [4] (`DTLSV1DOT0_OPENSSL_VERSION`). For these reasons, it seems to make sense to remove the fictional SSL 1 code entirely. This also removes an issue where the resulting JA4 string would be "s3" instead of the intended "s1". An earlier version of the JA4 spec [6] also mistakenly used 0x0200 for SSL 2 and 0x0100 for SSL 1. This was fixed in [7] in August 2024. [1] https://www-archive.mozilla.org/projects/security/pki/nss/ssl/draft02.html [2] https://datatracker.ietf.org/doc/html/draft-hickman-netscape-ssl-00 [3] https://github.com/openssl/openssl/blob/OpenSSL_0_9_6m/ssl/ssl2.h#L66-L71 [4] https://github.com/wireshark/wireshark/blob/release-4.4/epan/dissectors/packet-tls-utils.h#L266-L277 [5] https://github.com/openssl/openssl/compare/OpenSSL_0_9_8e...OpenSSL_0_9_8f [6] https://github.com/FoxIO-LLC/ja4/blob/main/technical_details/JA4.md#tls-and-dtls-version [7] FoxIO-LLC/ja4#150 * Fix tests where old DTLS (0x0100) was mis-identified as SSL 3.0 These two tests contain DTLS flows using a version field of 0x0100 as used by OpenSSL pre 0.9.8f, before OpenSSL switched to the standardised version code points for its DTLS implementation. The correct JA4 mapping is "d00", not "ds3".

| | | | | | | | | It might be usefull to be able to match traffic against a list of suspicious JA4C fingerprints Use the same code/logic/infrastructure used for JA3C (note that we are going to remove JA3C...) See: #2551

| | | | | In very old (G)QUIC versions by Google, the user agent was available on plain text. That is not true anymore, since about end of 2021. See: https://github.com/google/quiche/commit/f282c934f4731a9f4be93409c9f3e8687f0566a7

* Fix classification "by-port" (#2655)Ivan Nardi2025-01-06
| | | | | Classification "by-port" is the latest possible shot at getting a classification, when everything else failed: we should always use the configured ports (as expected by the users, IMO)

* TLS: fix `NDPI_TLS_WEAK_CIPHER` flow risk (#2647)Ivan Nardi2025-01-06
