Dealing with IO Exception: Connection reset with OWASP dependency-check Command Line Tool

We have summarized the actions to be taken when an error (IO Exception: Connection reset) occurs when executing a tool called OWASP dependency-check.

Roughly speaking, it was an error that occurred because the JDK used in the environment could not support the encryption suite specified by the site from which the vulnerability information was acquired. The solution was to add a library called BouncyCastle that provides an API for encryption to the JDK of the environment.

Originally, I was working on the cooperation between Vuls and OWASP dependency-check. https://vuls.io/docs/ja/usage-scan-non-os-packages.html#usage-integrate-with-owasp-dependency-check-to-automatic-update-when-the-libraries-are-updated-experimental

There was an Issue in the same situation. https://github.com/jeremylong/DependencyCheck/issues/561

It's long, but after all https://github.com/jeremylong/DependencyCheck/issues/561#issuecomment-257045439 It was that there was not enough Bouncy Castle.

There is also a comment that it is okay because the latest OpenJDK is included. https://github.com/jeremylong/DependencyCheck/issues/561#issuecomment-267774165

Cause

https://stackoverflow.com/questions/40305004/java-tls-connection-reset-using-some-jdks

The connection reset was set because the JDK cannot support the TLS communication encryption suite used by nvd.nist.gov, which provides vulnerability information.

Coping

It's OK if the JDK can support the corresponding encryption suite.

Add Bouncy Castle to the JDK

Run again

$ ./dependency-check/bin/dependency-check.sh -f XML -o ./result.xml -s /web/current/api/current --project dev-api -l ./owasp.log
[ERROR] Exception from bundle-audit process: java.io.IOException: Cannot run program "bundle-audit" (in directory "/tmp/dctemp668de20e-5168-4592-ada8-6b73ba425d34"): error=2,There is no such file or directory. Disabling Ruby Bundle Audit Analyzer

I got an error, but the error was because I was using Ruby in the environment to be scanned, that bundle-audit could not be executed.

https://rubygems.org/gems/bundler-audit

So, by now, the title error should have been resolved.

Install bundler-audit

In addition, I will also describe the bundle-audit settings. Is it easy.

$ sudo gem install bundler-audit

Run again

Change the output destination of the result to /tmp/result.xml

$ ./dependency-check/bin/dependency-check.sh -f XML -o /tmp/result.xml -s /web/current/api/current --project dev-api -l ./owasp02.log

It ended normally.

that's all.
