CVE-2019-16543: Plaintext Storage in Jenkins Spira Importer Plugin

The vulnerability stems from plaintext credential storage in the plugin's global configuration XML file. The primary vulnerable functions would be those responsible for serializing configuration data to disk. In Jenkins plugin architecture, the descriptor class (typically ending with $DescriptorImpl) handles configuration persistence through its configure method. The setter method for the password field would directly store plaintext values prior to the encryption fix in 3.2.3. These functions would appear in runtime profiling when administrators save plugin configuration or when the system writes to com.inflectra.spiratest.plugins.SpiraBuilder.xml.
