From 629f0742b04535ddaf052f9d3c4da3ec000ce411 Mon Sep 17 00:00:00 2001 From: "alejandro.gonzalez" Date: Mon, 23 Mar 2026 14:03:57 +0100 Subject: [PATCH 01/35] Instrument Jetty for server.request.body.filenames Add GetFilenamesAdvice to all three Jetty AppSec modules to collect uploaded file names from multipart requests and fire the requestFilesFilenames() IG callback: - jetty-appsec-8.1.3: intercepts getParts() return value; includes Content-Disposition header fallback for Servlet 3.0 (Jetty 9.0) where getSubmittedFileName() is not available - jetty-appsec-9.2: intercepts no-arg getParts() for Servlet 3.1+ - jetty-appsec-9.3: same, applies to Jetty 9.3, 10, 11 Enable testBodyFilenames() in Jetty 9.x, 10 and 11 server tests. ---

Add Jetty8LatestDepForkedTest: runs against Jetty 8.x (latestDepForkedTest task) and enables testBodyMultipart/testBodyFilenames coverage. Gated by 'test.dd.filenames' system property so it is skipped when running against Jetty 7.6. - Add testCompileOnly dep on org.eclipse.jetty.orbit:javax.servlet so MultipartConfigElement compiles without pulling in the excluded javax.servlet:javax.servlet-api artifact. - Fix ParameterCollector.put to accept (Object, Object) and cast internally: Jetty 8.x MultiMap.add uses (Object, Object) descriptor while Jetty 9.x uses (String, Object), so the ASM bytecode visitor was silently skipping all form field captures on Jetty 8. - Update GetPartsMethodVisitor to match both (String,Object) and (Object,Object) MultiMap.add descriptors and emit the INVOKEINTERFACE with (Object, Object). --- .../jetty8/ParameterCollector.java | 15 ++- .../RequestGetPartsInstrumentation.java | 6 +-

Add jetty-appsec-9.4 and jetty-appsec-11.0 to armeria-jetty-1.24 testRuntimeOnly classpath; these are required after the muzzle split that tightened jetty-appsec-9.3 to [9.3, 9.4.10) - Merge jetty-appsec-10.0 functionality into jetty-appsec-9.4: extend the muzzle from [9.4.10, 10.0) to also cover [10.0.10, 11.0) using _multiParts:MultiParts + javax.servlet.http.Part as discriminators; delete the now-redundant jetty-appsec-10.0 module - Delete intermediate modules jetty-appsec-10.0.10 and jetty-appsec-11.0.10 that were split-by-point-release and now handled by the two modules above - Scope server.request.body.filenames to Jetty 9.3+: revert filenames additions from jetty-appsec-8.1.3 (Jetty 8, EOL 2015) and jetty-appsec-9.2 (Jetty 9.2, EOL 2019) to stay within the 32 MiB agent JAR limit; requestBodyProcessed support for those versions is unchanged Agent JAR: 33,551,402 bytes (3,030 bytes under the 32 MiB limit) --- .../armeria/armeria-jetty-1.24/build.gradle | 2 + .../jetty-appsec-10.0.10/build.gradle | 23 -- .../jetty1010/MultipartHelper.java | 32 --- ...tractContentParametersInstrumentation.java | 235 ----------------- .../jetty-appsec-10.0/build.gradle | 23 -- .../jetty10/MultipartHelper.java | 32 --- ...tractContentParametersInstrumentation.java | 236 ------------------ .../jetty-appsec-11.0.10/build.gradle | 24 -- .../jetty1110/MultipartHelper.java | 32 --- ...tractContentParametersInstrumentation.java | 233 ----------------- .../jetty-appsec-11.0/build.gradle | 8 +- ...tractContentParametersInstrumentation.java | 14 +- .../jetty8/MultipartHelper.java | 38 --- .../RequestGetPartsInstrumentation.java | 70 +----- .../jetty8/MultipartHelperTest.groovy | 28 --- .../jetty92/MultipartHelper.java | 32 --- ...tractContentParametersInstrumentation.java | 53 ---- .../jetty92/MultipartHelperTest.groovy | 71 ------ .../jetty-appsec-9.4/build.gradle | 8 + ...tractContentParametersInstrumentation.java | 13 +- .../jetty-server-10.0/build.gradle | 9 +- .../jetty-server-11.0/build.gradle | 1 -
