Sonatype · Sonatype Nexus Repository Manager · CVE-2018-5307
**Name of the Vulnerable Software and Affected Versions**
Sonatype Nexus Repository Manager versions prior to 2.14.6
**Description**
The issue concerns multiple cross-site scripting (XSS) vulnerabilities. These vulnerabilities allow remote attackers to inject arbitrary web script or HTML via several parameters and fields, including the `repoId` or `format` parameter to the "service/siesta/healthcheck/healthCheckFileDetail/.../index.html" endpoint, the `filename` in the "File Upload" functionality of the Staging Upload, the `username` when creating a new user, or the IQ Server URL field in the IQ Server Connection functionality.
**Recommendations**
For versions prior to 2.14.6, update to version 2.14.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable endpoints and functionalities, such as limiting the ability to upload files or create new users, until a patch is applied. Avoid using the vulnerable parameters, such as `repoId`, `format`, `filename`, `username`, and IQ Server URL field, in the affected functionalities until the issue is resolved.
