Sonatype Nexus Repository Manager 3.20.0

Sonatype Nexus Repository 3 allows a user that holds the role create or role update permission to grant roles and privileges that the account does not hold. This can give the user more access than intended, up to full administrative access.

Sonatype Nexus Repository 3 allows an unauthenticated remote attacker to supply attacker-controlled input to a Java class loading call through an ExtDirect endpoint. This allows the attacker to learn whether specific classes are present in the application. The issue does not by itself allow code execution.

Nexus Repository 3 contained a privilege escalation vulnerability in the REST privileges API. An authenticated user with permission to manage privileges could, under certain role configurations, escalate their own access to full administrator by exploiting a type-confusion flaw in the privilege update endpoint.

A user holding a permission to update privilege definitions could modify a wildcard privilege already assigned to their own role to grant broader permissions than they were authorized to hold, including full administrative access, without any additional authorization check or role reassignment.

Nexus Repository 3 CE/Pro versions 3.0.0 through 3.94.x contain an incorrect authorization vulnerability (CWE-863) in the repository-creation user interface. An individual user account holding a delegated repository-admin privilege scoped to a specific repository format could create a repository of a different, unauthorized format, because authorization was checked against one request field while a separate, attacker-controlled field determined the repository format actually created. This does not affect the anonymous user, which cannot hold this privilege by default. Fixed in version 3.95.0.
