- →Stored XSS payload injected into the 'Description' field of the Project Naming Strategy configuration; payload is triggered when a user enters a non-compliant project name in the New Item creation page. ↗
- →Monitor POST requests to Jenkins /configure endpoint that set a Project Naming Strategy description containing HTML/JavaScript special characters (e.g., <, >, script tags) by users with Overall/Manage permission. ↗
- →XSS fires on the New Item page (newJob) when any character is typed into the name field, if a malicious description is already stored in the Project Naming Strategy. ↗
- ·Vulnerability only exploitable by users who hold Overall/Manage permission in Jenkins; lower-privileged users cannot set the Project Naming Strategy description. ↗
- ·Affected versions are Jenkins 2.251 and earlier (weekly) and LTS 2.235.3 and earlier; fixed in Jenkins 2.252 and LTS 2.235.4. ↗

jenkins: stored XSS vulnerability in project naming strategy
vendor_redhat·2020-08-12·CVSS 5.4
CVE-2020-2230 [MEDIUM] CWE-79 jenkins: stored XSS vulnerability in project naming strategy
jenkins: stored XSS vulnerability in project naming strategy
Jenkins 2.251 and earlier, LTS 2.235.3 and earlier does not escape the project naming strategy description, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by users with Overall/Manage permission.
A flaw was found in Jenkins in versions prior to 2.251 and LTS 2.235.3. The project naming strategy description, displayed on item creation, is not properly escaped. This can result in a stored cross-site scripting (XSS) vulnerability exploitable by users with Overall/Manage permissions. The highest threat from this vulnerability is to data confidentiality and integrity.
