[SECURITY] Use HTTPS to resolve dependencies in Maven Build #768

JLLeitschuh · 2020-02-11T02:15:46Z

This is a security fix for a vulnerability in your Apache Maven pom.xml file(s).

The build files indicate that this project is resolving dependencies over HTTP instead of HTTPS.
This leaves your build vulnerable to allowing a Man in the Middle (MITM) attackers to execute arbitrary code on your or your computer or CI/CD system.

This vulnerability has a CVSS v3.0 Base Score of 8.1/10.

POC code has existed since 2014 to maliciously compromise a JAR file in-flight.
MITM attacks against HTTP are increasingly common, for example Comcast is known to have done it to their own users.

This contribution is a part of a submission to the GitHub Security Lab Bug Bounty program.

Detecting this and Future Vulnerabilities

This vulnerability was automatically detected by LGTM.com using this CodeQL Query.

As of September 2019 LGTM.com and Semmle are officially a part of GitHub.

You can automatically detect future vulnerabilities like this by enabling the free (for open-source) LGTM App.

I'm not an employee of GitHub nor of Semmle, I'm simply a user of LGTM.com and an open-source security researcher.

This would not work. You can't switch to HTTPS and keep the port 8081.

Recommendation

Update the parent pom for jenkinsci and remove repositories from this pom entirely. Plugin poms should not need to be referencing repositories.

Changes like this could be broken out into a separate pull request. Don't mix changes if you're proposing a large change. This change isn't large but just general advice.

Recommendation

You can leave this. However, if you're interested in getting changes like this out faster than what is blocked by this pull request I recommend opening a separate pull request.

Why this note? GHPRB has a Jira project as well.

At this point it's hard to stop using either without a migration because there's many good reports in both locations.

Recommendation

Delete this line. Alternate recommendation, create a "Filing support issues" section and mention both GitHub issues and JIRA.

What is this file? It doesn't look like it provides anything beneficial to the project because

We're on GitHub.

GitHub issues are pretty standard across all GitHub projects unless it is disabled.

For projects that have GitHub issues disabled, they usually reference where issues are tracked off-site in the README.

As mentioned earlier, there's also GHPRB Jira tracker https://issues.jenkins-ci.org/browse/JENKINS-55793?jql=project%20%3D%20JENKINS%20AND%20status%20in%20(Open%2C%20%22In%20Progress%22%2C%20Reopened)%20AND%20component%20%3D%20ghprb-plugin%20ORDER%20BY%20created%20DESC

Recommendation

Delete this file.

I have no idea how my bot ended up generating such a wild diff.

I'm not currently able to fix this. Please feel free to close this.

I do reccomend still fixing the security issue in the POM files though
