In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode the password as bytes.

This was done because the initial specification for HTTP did not specify explicitly a charset, and it was assumed to be ISO-8859-1 for historical reasons.

If the password contains characters that cannot be represented in ISO-8859-1, they are silently replaced by `?`. This happens with passwords that contain Chinese, Cyrillic or Greek characters, for example: `αβ123` converts to `??123`.

An attacker can send a request with a digest `Authorization` header crafted with a password made of only `?` characters; the server would match any password of the same length that contains non-ISO-8859-1 characters.

Recent HTTP Digest [RFC-7616](https://datatracker.ietf.org/doc/html/rfc7616) supports a `charset` parameters that defaults to UTF-8 that allows for correct encoding/decoding of passwords.

GHSA-2fvj-hgj9-j2gr — Eclipse Jetty Digest Authentication: ISO-8859-1 lossy encoding allows authentication bypass via character substitution

Affected: Maven: org.eclipse.jetty:jetty-security, Maven: org.eclipse.jetty.ee8:jetty-ee8-security, Maven: org.eclipse.jetty.ee9:jetty-ee9-security

### Summary The `DigestAuthentication.apply()` method in Jetty's HTTP client uses `getBytes(StandardCharsets.ISO_8859_1)` at three locations (lines 171, 179, 196) to compute Digest auth response hashes. ISO-8859-1 silently replaces any character above U+00FF (Chinese, Japanese, Cyrillic, Arabic, Emoji, etc.) with 0x3F (`?`), causing all such characters to produce identical hash contributions. An attacker who knows a victim's username can bypass Digest authentication by replacing all non-Latin-1 characters in the password with `?` characters, since the collision password produces the same MD5-based Digest response hash as the original password.

### Details ### Root Cause

In `jetty-core/jetty-client/src/main/java/org/eclipse/jetty/client/DigestAuthentication.java`, the `apply()` method computes the three Digest auth hashes (H(A1), H(A2), and the final response) using ISO-8859-1 character encoding:

```java // Line 171 — H(A1) String hashA1 = toHexString(digester.digest(a1.getBytes(StandardCharsets.ISO_8859_1)));

// Line 179 — H(A2) String hashA2 = toHexString(digester.digest(a2.getBytes(StandardCharsets.ISO_8859_1)));

// Line 196 — Final response hash final String hashA3 = toHexString(digester.digest(a3.getBytes(StandardCharsets.ISO_8859_1))); ```

ISO-8859-1 (Latin-1) can only encode characters in the range U+0000–U+00FF. Any character outside this range — including all CJK, Cyrillic, Arabic, Greek, Hangul, and emoji characters — is silently replaced with the byte `0x3F`…
