  • Application and libraries grids in the UI flickered for users on Safari.
  • Some users had an issue onboarding multiple .NET applications in the same pool.
  • Impersonating users as a SuperAdmin resulted in errors.
  • Users without applications couldn't see custom access groups in the UI.
  • Applications tags were missing after applications were unmerged.
  • Application queries timed out in some organizations.
  • Daily digest emails were sent multiple times to the same recipients.
  • Filters weren't applied when using the "Select All" option to delete vulnerabilities or exporting vulnerabilities for merged applications.
  • Jira integrations didn't detect custom field to add multiple users.
  • Merged applications ignored an Assess rule disabled previously for one of the applications.


  • Export your application’s route coverage information to use and share outside the UI. To download the spreadsheet, go to the application’s Route Coverage tab, and select the icon above the grid to Export Routes to CSV. You can also export the same data via the APIs.

  • The Node agent is available in the default Node Pivotal Cloud Foundry buildpack. You can also set up the Contrast tile to send any vulnerabilities up to your organization.

  • The Java agent added support for IBM JDK 8.

Agent Updates

Java summary

The Java agent is now available through package managers from the Contrast Debian and Contrast RPM repositories. If host installation is right for you, you can also install the agent with the Exec Helper package for Ubuntu and Red Hat.

The Java team also made improvements to Protect rules, and turned off semantic analysis for SQL injection by default.

.NET agents

The .NET Framework and .NET Core teams fixed an issue that could taint some objects to be rendered incorrectly in the Contrast UI. We also improved creation of method signatures for methods with generic types. (This may invalidate previously created sanitizers and validators, if those signatures included generic types.)

.NET Framework summary

The .NET Framework team added a new Assess rule that detects when IIS is configured to send the unnecessary “X-Powered-By” header as well as a new Assess rule that detects when non-session cookies are missing the “secure” flag. We added a new Protect rule for ASP.NET applications that can block a potentially malicious file from being uploaded. We fixed a bug in which instrumentation could cause an error in applications using a specific version ( of System.Net.Http from a Nuget package instead of the BCL. We also added the following capabilities to our agent configuration:

  • The ability to change the agent’s service’s startup type to “Manual” via a command line flag on the installer (e.g., SERVICE_STARTUP_TYPE_MANUAL=1)
  • The ability to suppress the agent’s service’s startup after installation via a command line flag on the installer (e.g., SUPPRESS_SERVICE_START=1)
  • A workaround for applications that use Server.Transfer within error pages
    (See the agent.dotnet. restore_error_handling_after_sending_headers_behavior configuration flag.)

.NET Core summary

You can now use the .NET Core agent on servers that have the .NET Framework agent installed. The team also added new Assess rules that detect when cookies are missing http-only or secure flags.

Node.js summary

The Node team investigated and closed an issue in which Bluebird async implementation was polluting the Node domain implementation which resulted in extraneous vulnerability reports in the Contrast UI. The team also fixed incompatibilities with the Comment Event Formatting (CEF) specification in the security log. We updated the handling of route reporting when routes are registered after server startup. Finally, we implemented improvements in the handling of the CSP Header Misconfigured, SSJS and SSRF rules.

Ruby summary

The Ruby team delivers an expanded test suite to include Ruby Core String specs as well as support for trust-boundary-violation. The team added performance optimizations to limit the generation of reported stack traces, limit the reporting of agent classes in inventory mode, append and flush log messages. We also migrated tag range handling from Ruby to C.

Python summary

The Python team added additional support for handling Protect rules that need to introspect the response body for the Flask framework. We closed an issue where the HTTP Method Tampering rule was blocking requests using the WebDAV protocol and aligned the defaults for communicating with the Contrast Service. Finally, the team closed an issue related to compatibility with MySQL in Python 2.7.

You can’t perform that action at this time.
