OpENer commits and versions prior to Feb. ICS-CERT has also published an advisory today warning users of these issues. Last July, Claroty also shared AccessDB Parser, a testing, fuzzing, and reverse engineering tool that quickly parses Microsoft AccessDB files.Ĭlaroty also used AFL in its research into the OpENer stack we uncovered vulnerabilities that Claroty and the EIPStackGroup-the maintainers of the OpENer stack-are disclosing today.

The first two packages include JWThenticator, a key-based authentication package for cloud services applications, and NETunnel, a code package that enables network tunneling over HTTPS connections. As part of this initiative, we will be periodically releasing code packages we created to solve some of the unique challenges we’ve faced in the development of our products. This initiative allows Claroty to contribute to the shared pool of knowledge and tools in the open-source community. We invite you to check out Claroty Open Source, which was announced in January. This is not Claroty’s first open-source contribution. Anyone today who wants to run it, can compile the updated OpENer EtherNet/IP stack code and immediately start fuzzing it without any changes. The inclusion of our integration code in the OpENer stack relieves anyone using the project from the significant coding normally required to modify source code and write scripts necessary to integrate a fuzzer. We did our best to add relevant documentation to the project so the onboarding process will be simple for anyone, including folks with no cybersecurity background. AFL uses runtime guided techniques to create input for the tested program. In this case, we modified OpENer and added all the necessary boilerplate code in a way that would help integrate the popular AFL (American Fuzzy Lop) fuzzer, into the OpENer stack.

Moving forward, Claroty’s work has simplified the efforts of any commercial entity or researcher using OpENer in their projects to invoke a fuzzer and test the security and robustness of their implementation.Ī peek at the AFL fuzzer in action uncovering bugs in the OpENer EtherNet/IP stack.įuzz-testing tools are automated programs that use invalid or random data as structured software inputs, and monitor outputs for crashes or exploitable vulnerabilities.

The Claroty Research Team, as part of its further research into the security of the OpENer stack, today announces that it has added the necessary infrastructure to incorporate the popular AFL fuzzer into the OpENer EtherNet/IP stack. Integrating a fuzzer, however, can be a challenge in an open source implementation requiring substantial development efforts, for example to ensure fuzzed input is correctly dissected. In that context, fuzz-testing code is the most straightforward and automated way to find coding errors and potentially critical flaws.

Its popularity among the major SCADA vendors that use it puts a premium on finding security vulnerabilities before threat actors can exploit them. The OpENer EtherNet/IP stack implements the familiar ENIP and CIP protocols that run inside numerous commercial products for use across the industrial domain.
