How to Fix CVE-2023-32993

To remediate this vulnerability, upgrade all affected Miniorange saml sp dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.jenkins.plugins:miniorange-saml-sp fixed: 2.1.0 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>miniorange-saml-sp</artifactId>
    <version>2.1.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-32993, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugins

Analyze the terminal output to locate any version of Miniorange saml sp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins.plugins command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-345: Insufficient Verification of Data Authenticity, where the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. In Miniorange saml sp, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Jenkins SAML Single Sign On(SSO) Plugin 2.0.2 and earlier does not perform hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata. This lack of validation could be abused using a man-in-the-middle attack to intercept these connections. SAML Single Sign On(SSO) Plugin 2.1.0 performs hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata.
