Restrict edit permission on hosted R repositories (nx-repository-view-r-*-edit) to fully trusted users and do not grant it to the anonymous user. Delete any unused hosted R repositories. Restrict network-level access to the Nexus Repository web interface to trusted networks only.

Technical details

This is a stored cross-site scripting vulnerability in the Browse user interface affecting R repository metadata handling. An authenticated user with the nx-repository-view-r-*-edit permission can upload an R package with embedded script content in its metadata. The script executes in the browser of any user who views the package details, running with that user's permissions; if an administrator views it, the attacker gains administrative access to the instance.

Affected products

Sonatype Nexus Repository 3 3.28.0 to 3.96.x
