Background
The Jenkins dbCharts Plugin is a Maven package that provides functionality for generating charts and graphs based on data stored in a database. It is commonly used in Jenkins CI/CD pipelines to visualize data from various sources. The plugin allows users to configure JDBC connections to connect to databases and retrieve data for chart generation. However, versions 0.5.2 and earlier of the plugin store JDBC connection passwords in plain text in the global configuration file hudson.plugins.dbcharts.DbChartPublisher.xml on the Jenkins controller. This vulnerability exposes sensitive information and puts the security of the database at risk.
Vulnerability Detail
The vulnerability in the Jenkins dbCharts Plugin arises from the insecure storage of JDBC connection passwords. These passwords are stored unencrypted in the global configuration file, which can be accessed by users with file system access to the Jenkins controller. This means that any user with such access can view the passwords and potentially gain unauthorized access to the associated databases. The impact of this vulnerability depends on the sensitivity of the data stored in the databases and the level of access granted to the compromised accounts.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, users can manually encrypt the passwords stored in the global configuration file. This can be done by using a secure encryption algorithm and updating the file with the encrypted passwords. However, this workaround is not recommended as it requires manual intervention and may introduce additional security risks if not implemented correctly. It is strongly advised to apply the official fix provided by the plugin maintainers.
Conclusion
The Jenkins dbCharts Plugin versions 0.5.2 and earlier suffer from a vulnerability that exposes JDBC connection passwords stored in plain text. This can lead to unauthorized access to associated databases and potential data breaches. To mitigate this risk, it is crucial to upgrade to a fixed version of the plugin, such as version 0.5.3 or later, which encrypts the stored passwords. It is also recommended to review and update any stored passwords in the global configuration file to ensure they are properly encrypted and protected.
