Semmle employee Man Yue Mo disclosed details about the vulnerability CVE-2018-11776 of the framework for creating web applications called Apache Struts. The problem was discovered in April 2018. It allowed to remotely run malicious code and grab control over the web server.

The problem was the configuration of the framework, which allowed errors to appear in two cases:

  • if the alwaysSelectFullNamespace parameter was set to true;
  • if the action and url tags did not contain a namespace attribute, or if wildcard characters were used instead.

The attack began with a transition through a pre-configured link to a vulnerable web server. Further attackers were able to launch malicious code to capture control over the application.

Vulnerability was present in all web applications based on Apache Struts 2.3 versions prior to Struts 2.5.16. With the correct configuration file, the application could be invulnerable, but the risk of hacking increased even with the slightest change. The developers fixed the bug in versions of Apache Struts 2.3.35 and 2.5.17.

Oracle developers announced the release of the Java 11 standard and its implementation of the JDK (Java Development Kit) with a long support period up to 2026. It is fully compatible with previous versions. Support for Java 8 will end in December 2020, and Java 10 won't receive any updates.

New in Java SE 11

  • Nest-Based Access Control system implemented
  • The .class format is complemented by the support for the CONSTANT_Dynamic forms, which are loaded by the creation of constants to the bootstrap method.
  • Added support for the latest version of the transport layer security protocol - TLS 1.3. It accelerates the loading of mobile web pages, and also filters out old, vulnerable cryptographic primitives, replacing them with more complex encryption algorithms.
  • Standardized support for the HTTP Client API, introduced in the Java 9 incubator.
  • Epsilon garbage collector is launched in a test mode.
  • The Java EE and CORBA modules are removed from the JDK and the Java SE platform, and the Nashorn engine and the Pack200 tools are declared obsolete.
  • The JavaFX module is excluded from the kernel and is shipped separately.
  • Existing APIs are updated to support the Unicode 10 format.
  • Added tools for streaming low-level data on errors and problems.
  • Added the ability to run single-file programs that contain the source code.

More information about the changes can be found on the Release Notes page of JDK 11.

The previous, intermediate version of the standard and JDK 10 came out in March 2018. A set of development tools has received three new variants of Java virtual machines, the sharing of application classes and the support of the experimental Just-in-Time compiler on Linux / x64.
