file-parameters is vulnerable to Path Traversal
88
High Risk
This Affects:
file-parametersTL;DR
A @DataBoundConstructor path in File Parameter Plugin stores uploaded files using a parameter name as a path without applying the existing safety validation. Attackers able to submit certain forms can write files to arbitrary controller filesystem locations, including paths that can lead to code execution. The fix applies the same parameter name validation in that constructor.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and users can submit forms that bind File Parameter plugin definitions.
Background info
file-parameters is vulnerable to Path Traversal in versions 0.0.1 - 425.
How to fix this
Upgrade the io.jenkins.plugins:file-parameters library to the patch version.
