From c542c6b605465fe46ad4fd023dd1537b0f4c81cf Mon Sep 17 00:00:00 2001 From: "alejandro.gonzalez" Date: Mon, 1 Dec 2025 15:25:45 +0100 Subject: [PATCH 01/34] [appsec] Add Remote Config subscription for ASM_SCA product Implements Remote Config infrastructure for Supply Chain Analysis (SCA) vulnerability detection via dynamic instrumentation. This commit adds: - New Product.ASM_SCA enum value for Remote Config product type - CAPABILITY_ASM_SCA_VULNERABILITY_DETECTION capability flag (bit 47) - AppSecSCAConfig data model with InstrumentationTarget (className/methodName) - AppSecSCAConfigDeserializer for JSON deserialization - subscribeSCA()/unsubscribeSCA() lifecycle methods in AppSecConfigServiceImpl - Integration into Remote Config subscription/cleanup flows The subscription stores incoming SCA configs in currentSCAConfig field. Actual bytecode retransformation will be implemented in future commits when AppSecInstrumentationUpdater is added. --- .../config/AppSecConfigServiceImpl.java | 51 ++++++++ .../appsec/config/AppSecSCAConfig.java | 44 +++++++ .../config/AppSecSCAConfigDeserializer.java | 30 +++++ ...ppSecConfigServiceImplSpecification.groovy | 39 ++++++ .../AppSecSCAConfigDeserializerTest.groovy | 108 +++++++++++++++++ .../appsec/config/AppSecSCAConfigTest.groovy | 113 ++++++++++++++++++ .../datadog/remoteconfig/Capabilities.java | 2 + .../java/datadog/remoteconfig/Product.java | 1 + 8 files changed, 388 insertions(+) create mode 100644 dd-java-agent/appsec/src/main/java/com/datadog/appsec/config/AppSecSCAConfig.java create mode 100644 dd-java-agent/appsec/src/main/java/com/datadog/appsec/config/AppSecSCAConfigDeserializer.java create mode 100644 dd-java-agent/appsec/src/test/groovy/com/datadog/appsec/config/AppSecSCAConfigDeserializerTest.groovy create mode 100644 dd-java-agent/appsec/src/test/groovy/com/datadog/appsec/config/AppSecSCAConfigTest.groovy diff --git a/dd-java-agent/appsec/src/main/java/com/datadog/appsec/config/AppSecConfigServiceImpl.java b/dd-java-agent/appsec/src/main/java/com/datadog/appsec/config/AppSecConfigServiceImpl.java index fae17c9531d..016495b330e 100644 --- a/dd-java-agent/appsec/src/main/java/com/datadog/appsec/config/AppSecConfigServiceImpl.java +++ b/dd-java-agent/appsec/src/main/java/com/datadog/appsec/config/AppSecConfigServiceImpl.java @@ -21,6 +21,7 @@ import static datadog.remoteconfig.Capabilities.CAPABILITY_ASM_RASP_SQLI; import static datadog.remoteconfig.Capabilities.CAPABILITY_ASM_RASP_SSRF; import static datadog.remoteconfig.Capabilities.CAPABILITY_ASM_REQUEST_BLOCKING; +import static datadog.remoteconfig.Capabilities.CAPABILITY_ASM_SCA_VULNERABILITY_DETECTION; import static datadog.remoteconfig.Capabilities.CAPABILITY_ASM_SESSION_FINGERPRINT; import static datadog.remoteconfig.Capabilities.CAPABILITY_ASM_TRACE_TAGGING_RULES; import static datadog.remoteconfig.Capabilities.CAPABILITY_ASM_TRUSTED_IPS; @@ -103,6 +104,7 @@ public class AppSecConfigServiceImpl implements AppSecConfigService { private boolean hasUserWafConfig; private boolean defaultConfigActivated; private final AtomicBoolean subscribedToRulesAndData = new AtomicBoolean(); + private final AtomicBoolean subscribedToSCA = new AtomicBoolean(); private final Set usedDDWafConfigKeys = Collections.newSetFromMap(new ConcurrentHashMap<>()); private final Set ignoredConfigKeys = @@ -110,6 +112,7 @@ public class AppSecConfigServiceImpl implements AppSecConfigService { private final String DEFAULT_WAF_CONFIG_RULE = "ASM_DD/default"; private String currentRuleVersion; private List modulesToUpdateVersionIn; + private volatile AppSecSCAConfig currentSCAConfig; public AppSecConfigServiceImpl( Config tracerConfig, @@ -134,6 +137,8 @@ private void subscribeConfigurationPoller() { log.debug("Will not subscribe to ASM, ASM_DD and ASM_DATA (AppSec custom rules in use)"); } + subscribeSCA(); + this.configurationPoller.addConfigurationEndListener(applyRemoteConfigListener); } @@ -345,6 +350,51 @@ private void subscribeAsmFeatures() { this.configurationPoller.addCapabilities(CAPABILITY_ASM_AUTO_USER_INSTRUM_MODE); } + /** + * Subscribes to Supply Chain Analysis (SCA) configuration from Remote Config. + * Receives instrumentation targets for vulnerability detection in third-party dependencies. + */ + private void subscribeSCA() { + if (subscribedToSCA.compareAndSet(false, true)) { + log.debug("Subscribing to ASM_SCA Remote Config product"); + this.configurationPoller.addListener( + Product.ASM_SCA, + AppSecSCAConfigDeserializer.INSTANCE, + (configKey, newConfig, hinter) -> { + if (newConfig == null) { + log.debug("Received removal for SCA config key: {}", configKey); + currentSCAConfig = null; + // TODO: Trigger retransformation to remove instrumentation when updater exists + } else { + log.debug( + "Received SCA config update for key: {} - enabled: {}, targets: {}", + configKey, + newConfig.enabled, + newConfig.instrumentationTargets != null + ?
