Background
The Jenkins Copr Plugin is a Maven package that allows users to store and manage credentials for Jenkins jobs. It is commonly used in software development and continuous integration workflows. The plugin provides a convenient way to store and access sensitive information such as usernames, passwords, and API keys. However, versions 0.3 and earlier of the plugin have a vulnerability that stores these credentials in plain text in the job configuration files. This means that anyone with Extended Read permission or access to the Jenkins controller file system can view these credentials, potentially leading to unauthorized access and misuse of sensitive information.
Vulnerability Detail
The vulnerability (CVE-2020-2177) in the Jenkins Copr Plugin arises from the insecure storage of credentials in plain text. This allows unauthorized users to easily access and view sensitive information stored in the job configuration files. The impact of this vulnerability can be significant, as it exposes credentials that may grant access to external systems, APIs, or databases. The vulnerability has a CVSS score of 4.3, indicating a moderate level of severity.

Workaround
If upgrading to the latest version is not immediately feasible, a temporary workaround is to manually encrypt the credentials before storing them in the job configuration files. This can be done using encryption tools or libraries available in the programming language used for the Jenkins job. However, this workaround is not recommended as it requires additional effort and may introduce potential security risks if not implemented correctly.
Conclusion
The Jenkins Copr Plugin vulnerability (CVE-2020-2177) exposes credentials stored in plain text, potentially leading to unauthorized access and misuse of sensitive information. To mitigate this vulnerability, it is crucial to upgrade to version 0.6.1 or later of the plugin, which introduces encryption for the stored credentials. Additionally, it is recommended to regularly check for vulnerabilities in your Jenkins installation using tools like Vulert Playground (https://vulert.com/scanner) and consider alternative plugins or solutions for managing credentials.
