saml is vulnerable to Improper Access Control
88
High Risk
This Affects:
samlTL;DR
A constructor annotated with @DataBoundConstructor writes SAML identity provider metadata to the controller file system. Attackers able to submit certain forms can overwrite identity provider metadata with attacker-controlled content without required permission and then authenticate as arbitrary users. The fix requires Overall/Administer permission 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 SAML plugin identity provider metadata configuration.
Background info
saml is vulnerable to Improper Access Control in versions 0.0.1 - 4.618.
How to fix this
Upgrade the org.jenkins-ci.plugins:saml library to the patch version.
