CVE-2023-24439: 
Java vulnerability analysis and mitigation

CVE-2023-24439 is a security vulnerability affecting the JIRA Pipeline Steps Plugin version 2.0.165.v8846cf59f3db and earlier in Jenkins. The vulnerability was disclosed on January 24, 2023, as part of Jenkins Security Advisory 2023-01-24. This vulnerability is related to the storage of private keys in plain text within the plugin's configuration (Jenkins Advisory).

The vulnerability has been assigned a severity rating of Low (CVSS). The technical issue involves the plugin storing private keys unencrypted in its global configuration file 'org.thoughtslive.jenkins.plugins.jira.JiraStepsConfig.xml' on the Jenkins controller. Additionally, the global configuration form does not mask the API key, which increases the potential for attackers to observe and capture it (Jenkins Advisory).

The impact of this vulnerability is that users with access to the Jenkins controller file system can view the unencrypted private key stored in the configuration file. The lack of masking in the global configuration form also increases the risk of credential exposure through shoulder surfing or screen capture (Jenkins Advisory).

As of the publication of the Jenkins security advisory, there is no fix available for this vulnerability in the JIRA Pipeline Steps Plugin. Users are advised to restrict access to the Jenkins controller file system and implement additional security measures to protect sensitive configuration information (Jenkins Advisory).
