New features and enhancements

Improved attack detection

Application Security | Attacks

Improved attack detection for Command injections and JNDI injections.

Entry point information for code-level vulnerabilities

Application Security | Vulnerabilities

Every detected code-level vulnerability now shows all application paths that let a user potentially exploit this vulnerability. This helps developers and security engineers with evaluating the vulnerability and verifying a potential fix.

The code-level vulnerability details page now shows the entry points (URLs/paths) and the user-supplied inputs (such as HTTP parameters) that can be abused.

Enabled event ingest on OneAgent localhost interface

Infrastructure Monitoring | Events

Event ingest (similar to log and metric ingest) is enabled on the OneAgent localhost interface.

General

  • The OneAgent JavaScript module's signature check is temporarily disabled by default. This was done to mitigate high network traffic between the cluster and OneAgent caused by JavaScript agents older than 2 years having an out-of-date signature, which resulted in an invalid signature check. In a follow-up issue, we will update the signature checking mechanism and enable the signature check as the default again. (OA-19400)
  • Injection of the OneAgent IIB code module is no longer reported as failed for platforms where it is not supported. (OA-17439)

OS module

  • Fixed high agent CPU usage on hosts with high network traffic. (HOST-3156)
  • Fixed an issue where disk exclusion rules were applied only to local disks. (HOST-3221)
  • Fixed issue where, from time to time on network shares, there were spikes of usage that showed throughput in PiB/s. (HOST-3218)
  • Fixed Node.js technology detection for the process running inside a container. (HOST-3139)
  • Fixed an issue where df did not spawn a process correctly even after it stopped being spawned, which could result in disk metrics not being updated. (HOST-3155)
  • Excluded administrative and local shares from statistics for network shares. (HOST-3219)
  • OneAgent OS module will now time out after 2s when stuck on WMI class access. (HOST-3122)
  • Disabled Windows network drive monitoring in response to API hanging in certain scenarios. (HOST-3206)

Java

  • Resolved an issue that, after OneAgent upgrade, caused a NullPointerException in jdk.internal.net.http.HttpClient when lowercase headers for X-dynaTrace were present. (OA-18008)

.NET

  • AspNet sensor: improved handling for retrieving context in ASP-hosted WCF apps. (OA-19004)
  • Improved robustness of OneAgent version detection for .NET Core. (OA-18430)
  • Improved stability of the .NET code-level vulnerability/attack evaluation OneAgent feature. (OA-18007)
  • Improved queue name detection for OneAgent code module for .NET MSMQ monitoring. (OA-17904)
  • Improved stability of the .NET code-level vulnerability/attack evaluation OneAgent feature. (OA-18405)
  • Improved OneAgent .NET code module stability following the Microsoft security update for .NET framework 3.5. (OA-18223)

PHP

  • Resolved an issue that caused a `500 internal server error` when signing in with PHP deep monitoring enabled. (OA-18507)

Node.js

  • Corrected an issue that sometimes caused OneAgent to fail to retrieve the MongoDB hostname from the configuration URL in calls to a MongoDB database, which resulted in those calls appearing as unexpected services in the Dynatrace web UI. (OA-16588)
  • Fixed a memory leak caused by the Node.js code module, which was introduced by a module-internal optimization (since reverted). (OA-19275)

OpenTracing module

  • Envoy: fixed `overwritten1.http.status_code` occurring in Grail. For Envoy spans, in addition to `http.status_code`, a stray attribute `overwritten1.http.status_code` was occurring. Now only one `http.status_code` (type integer) occurs. (OA-17243)

NGINX

  • NGINX instrumentation has been updated for currency with NGINX 1.25. (OA-17247)
