How to Fix CVE-2023-50777

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

com.cloudtp.jenkins:paaslane-estimate fixed: Latest secure release 
<dependency>
    <groupId>com.cloudtp.jenkins</groupId>
    <artifactId>paaslane-estimate</artifactId>
    <version>Latest secure release</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=com.cloudtp.jenkins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-50777, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.cloudtp.jenkins

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

Note: The mvn dependency:tree -Dincludes=com.cloudtp.jenkins 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-312: Cleartext Storage of Sensitive Information, where the product stores sensitive information in cleartext within a resource that might be accessible to another control sphere. In Paaslane estimate, 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 PaaSLane Estimate Plugin 1.0.4 and earlier does not mask PaaSLane authentication tokens displayed on the job configuration form, increasing the potential for attackers to observe and capture them.
