Prove attachment security against WSS4J in all four directions - #1
Conversation
The attachments suite proved multipart round-tripping with no security at all, so nothing here had ever checked a signed or encrypted attachment against a real peer. That is the coverage this feature needed most: the digest and the ciphertext both run over the attachment's raw octets, with no canonicalization and no transfer-encoding step, so any disagreement about what those octets are shows up as a bare digest mismatch or a failed tag and says nothing about why. The missing piece on the oracle side was the callback handler. WSS4J never reads a multipart body itself; signing, verifying, encrypting and decrypting an attachment all go through AttachmentRequestCallback and AttachmentResultCallback, so without one it has no attachment to work on and reports nothing rather than failing. Three things about it were only learnable by reading the jar: - WSS4J compares "cid:Attachments" against WSEncryptionPart.getId(), not getName(), and passes it through AttachmentUtils.getAttachmentId first, so what reaches the handler is the bare id "Attachments" meaning "all of them". Treating it as a Content-ID to look up finds nothing and the signature comes out with no attachment reference at all, silently. - The SwA transform providers are registered by WSSConfig.init(). The engine paths trigger it lazily; a standalone message-builder path does not, and the signature factory then reports the content transform as "algorithm and DOM mechanism not available". - Verifying a sign-then-encrypt message asks for an attachment twice: the EncryptedKey is processed first and delivers the plaintext back, then the signature asks for something to digest. Answering the second question with the ciphertext fails every attachment digest. The PHP tests assert on the digest of each attachment *after* processing, because a decryption that recovered nothing also does not fail. Both tamper cases are covered from both sides, and the text/* refusal is pinned so it stays a decision rather than an accident. These live in the wsse suite: attachment security is WS-Security, and it keeps the attachments suite meaning "multipart packaging, no security", which is what its own package cares about. No workflow change needed in either repo.

…are refused The four directional cases now run twice, once per packaging. The encryption case reads the part as it crossed the wire and asserts it was ciphertext there, which is what fails if a peer resolves the xop:Include before its security interceptor runs. It does not: all four directions hold under MTOM. MTOM here means SOAP 1.2. The attachments middleware writes start-info="application/soap+xml" whatever the envelope says, and SAAJ reads a SOAP 1.1 XOP package as one whose start-info is text/xml, so a 1.1 envelope in an MTOM package is refused before any security processing happens. The pinned refusal grows an XML row, and gains the measurement behind it: WSS4J signs a text part whose content mixes bare LFs with CRLFs, and the digest it publishes is the one over the normalized form. A control case with line endings already normalized verifies, isolating the normalization as the whole of the disagreement. The oracle reports the pre-processing digests alongside the post-processing ones, and escapes control characters in its JSON, which a folded Content-Type in an error message had been breaking.
…red it check() read the action tag alone, so a message that signed nothing but its Body reported "signature: true" and satisfied the "no signature over the attachments" rule. Every PHP-signs case would have passed without covering the attachment at all. WSS4J marks a data reference as an attachment and records the cid: URI it named, so the answer is to require every inbound part to appear among them. Confirmed by dropping withAttachments() from the outbound side: three cases that used to pass now report the missing coverage. Reported by CodeRabbit on #1.

A bare sp:Attachments policy means the complete coverage on the dominant Java stack, and the two sides can disagree on the canonicalized header block in a way that surfaces as nothing but a digest mismatch. So the oracle now reports the block it computed, and a test compares it against the one PHP composed for the same part. They agree byte for byte, trailing CRLF layout included. The oracle takes signcover and enccover, so both operations can be driven in either coverage. Two fixes were needed for it to model a real peer: attachmentsOf() copies every MIME header a part travelled with rather than the two SAAJ exposes as accessors, which is what a coverage of a part's metadata canonicalizes; and emit() writes those headers back rather than letting SAAJ default them. Six cases: both signing directions under both packagings, the coverage refusal inbound, a complete decryption that recovers the header set from inside the ciphertext, the mixed sign-complete with encrypt-content-only case, and the header form this package refuses rather than guesses at. escapeJson escapes CRLF instead of flattening it, without which a reported header block cannot be compared against anything.

Pushed The case that matters is
Six new cases: both signing directions under both packagings, the coverage refusal inbound, a complete
|
The canonicalizer's rules were written from a reading of what WSS4J does, and a reading is what this feature was already caught out by once. Its unit tests were known-answer tests against that reading, and only one header shape had ever been put in front of the real thing. One row per rule now. Each hands WSS4J the same part and requires two things of it: that the block it canonicalized equals ours, and that the signature over that block verifies. The comparison comes first and carries both forms, because a disagreement otherwise surfaces as nothing more useful than "the signature or decryption was invalid". It found one. Content-Description is the only one of the five headers a peer canonicalizes without stripping the whitespace a MIME parser leaves after the colon, so its digest turns on whether the peer's own parser trimmed the separator. That header is refused now, and the row became the case pinning it. The oracle reports the header blocks on a refusal too. They were only reported on success, which is the one outcome that does not need them.
The suite already measured that WSS4J digests the CRLF-normalized form of a text part. It measured nothing about whether PHP agrees, because PHP refused to sign one at all. Now both directions sign content that mixes bare LFs, bare CRs and CRLFs, so the two normalizations have to produce the same bytes rather than merely both existing. Removing the normalization on the PHP side fails both. The refusal provider keeps XML alone, and gains a +xml subtype.
The suite measured that WSS4J canonicalizes an XML attachment's content and that PHP would not sign one. Both sides sign one now, so what needs pinning is that the two canonicalizations agree. Three shapes, each chosen so the canonical form differs from the octets: a processing instruction outside the root, an unused namespace declaration with unordered attributes and a comment, and a default namespace redeclared on a child. Each runs in both directions. The first is also what says the node-set is the document rather than the root element. One refusal is added and is the reason the doctype question is settled: the oracle's parser rejects a DOCTYPE outright, so refusing one here is the two stacks agreeing rather than a restriction invented on this side.

A complete coverage digests the canonical MIME header block and the content the transform produced. Nothing said which order those two steps happen in, and for the cases the suite already had it makes no difference: a binary part's transform is the identity, and a text part's leaves a header block that already ends every line in CRLF alone. XML is where it shows, so these run the three canonical-form shapes under a complete coverage in both directions. Composing before transforming instead hands the canonicalizer a header block to parse and fails all of them. The text case is here too, pinning the coincidence as a fact about the data rather than an accident nobody would notice breaking.
Direction times coverage times media type is twelve cells and eleven were filled. The missing one was a peer signing a text attachment under a complete coverage. That shape of gap is what let the ordering bug through. Each axis had cases: complete coverage was tested, and so was every media type. They were never crossed, and the complete cases were all binary, where the transform is the identity and no ordering can show.

The
attachmentssuite proved multipart round-tripping with no security at all, so nothing here had ever checked a signed or encrypted attachment against a real peer. This adds that, for the attachment-security work inphp-soap/http-wsse-middleware.This is the coverage that feature needed most. The digest and the ciphertext both run over the attachment's raw octets, with no canonicalization and no transfer-encoding step, so any disagreement between the two stacks about what those octets are surfaces as a bare digest mismatch or a failed GCM tag, with nothing to say why.

Plus sign-then-encrypt end to end, a tampered attachment refused from both sides, and the signing refusals pinned so they stay decisions rather than accidents.
Every assertion is on the SHA-256 of each attachment after processing, not merely on a green verdict: a decryption that recovered nothing also does not fail.
The oracle side
The missing piece was a callback handler. WSS4J never reads a multipart body itself. Signing, verifying, encrypting and decrypting an attachment all go through
AttachmentRequestCallback/AttachmentResultCallback, so without one WSS4J has no attachment to work on and reports nothing rather than failing.Three things about it were only learnable by reading the 3.0.4 jar, and each one failed silently or misleadingly:
cid:AttachmentsagainstWSEncryptionPart.getId(), notgetName(), and passes it throughAttachmentUtils.getAttachmentIdfirst, so what reaches the handler is the bare idAttachments, meaning "all of them". Treating it as a Content-ID to look up finds nothing, and the signature comes out with no attachment reference at all. Nothing complains.WSSConfig.init(). The engine paths trigger it lazily; a standalone message-builder path does not, and the signature factory then reports the content transform asalgorithm and DOM mechanism not available.EncryptedKeyis processed first and delivers the plaintext back through the result callback, then the signature asks for something to digest. Answering the second question with the ciphertext fails every attachment digest, and WSS4J surfaces it as a bareFAILED_CHECK.New oracle endpoints, both taking and returning a multipart body:
POST /attach/secure?signatt=&encatt=signs and/or encrypts a plain multipart, for the PHP verifier and decryptor to consume.POST /attach/check?signatt=&encatt=runs the WSS4J engine over a PHP-secured multipart and reports what it made of it plus the post-processing digests.ScenarioConfiggainsattachments.sign/attachments.encrypt(query:signatt,encatt). The existingSignerandEncryptorare untouched: they take XML alone and are used by most of the matrix, soAttachmentSecuritydoes its own WSS4J calls rather than destabilising them.Suite placement
These go in the
wssesuite, deliberately. Attachment security is WS-Security, and keeping it there leaves theattachmentssuite meaning "multipart packaging, no security", which is what its own package cares about. So neither consumer repo'sinterop.ymlneeds a change:http-wsse-middlewarestayssuites: wsseandpsr18-attachments-middlewarestayssuites: attachments.Verification
make interopfrom clean (jar, images, certs, up, both suites, down): 78 tests, 177 assertions, all green. The one deprecation is pre-existing.Two keystore facts worth recording, since they cost time: the oracle holds a single PKCS#12 with only the java-server private key, so PHP must encrypt to
java-server.crtand the oracle encrypts tophp-client; and the PHP side opens that withphp-client.key, not the.pem.Depends on
php-soap/http-wsse-middlewarebranchfeature/attachment-security, which the harness picks up through its composer path repository. Not mergeable before that lands.Update: MTOM, the refusals, and a false pass in the oracle
The MTOM release gate is closed. The content-only blueprint asked whether a WSS4J or CXF peer sees the plaintext for an MTOM-packaged encrypted part, and said to settle it empirically before release. It holds: all four directions pass under
AttachmentType::Mtom, and the encryption case reads the part as it crossed the wire and asserts it was ciphertext there, which is what would fail if the peer resolved thexop:Includeahead of its security interceptor.MTOM here means SOAP 1.2. The attachments middleware writes
start-info="application/soap+xml"into an MTOMContent-Typewhatever the envelope says, and SAAJ recognizes a SOAP 1.1 XOP package only whenstart-infoistext/xml, so a 1.1 envelope inside an MTOM package is refused at parse time, before any security processing. The MTOM rows use the SOAP 1.2 sample andprotocol=soap12. SOAP 1.1 plus MTOM, the WCF/CXF convention, is not expressible by the attachments package at all: a gap in that repo, not this one.The
text/*refusal is not going away, and it grew. The follow-up blueprint listed "WSS4J performs notext/*content canonicalization anywhere" as a verified fact and scheduled deleting it.AttachmentContentSignatureTransformin wss4j-ws-security-dom 3.0.4 branches three ways before digesting: exclusive C14N for XML content, CRLF normalization for every othertext/*, and the octets as they are for the rest. Deleting the refusal made PHP sign atext/plainattachment and WSS4J answer "The signature or decryption was invalid".The suite now measures the mechanism rather than reading it off the profile: WSS4J signs a text part whose content mixes bare LFs with CRLFs, and the
ds:DigestValueit publishes is the one over the normalized form. A control case whose two forms coincide verifies, isolating the normalization as the whole of the disagreement. The pinned refusal gained an XML row alongside the text one.The oracle was reporting a false pass, found by CodeRabbit on this PR and fixed in
c0d016a.check()setsignature: truefrom the WSS4J action tag alone, so a message that signed nothing but its Body satisfied the "no signature over the attachments" rule. Every PHP-signs case could have passed without covering the attachment at all. It now requires every inbound part to appear among the data references WSS4J marks as attachments. Confirmed by droppingwithAttachments()from the outbound side: three cases that used to pass report the missing coverage.check()also reportsrawSha256, the digests taken before processing, which is what lets the MTOM encryption case say the payload crossed the wire as ciphertext. AndescapeJsonnow escapes control characters, which a foldedContent-Typein an error message had been turning into an unparseable response.85 tests across both suites, green via
