Sonatype: >> Nexus Repository Manager >> 3.25.0-03 Security Vulnerabilities
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.

Nexus Repository 3 did not fully sandbox JEXL expressions used in Content Selectors. An account holding the nexus:selectors:create permission could construct an expression that read Java object properties not intended to be exposed to the expression engine, disclosing internal JVM class metadata such as class and classloader names. This issue does not permit method invocation, object construction, or arbitrary code execution. This has been fixed by restricting property access in the JEXL sandbox to the intended data types.

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.

Nexus Repository 3 does not validate the destination of the "Webhook: Global" capability's configured URL before making an outbound HTTP request, allowing a user holding the Capability Administration permission to cause the server to send requests to internal network locations (Server-Side Request Forgery). This permission is granted by role assignment, independent of authentication status, so an unauthenticated user could also trigger this behavior if the anonymous role has been granted the permission.

Nexus Repository 3 did not apply its existing Server-Side Request Forgery (SSRF) protections to HTTP redirect targets returned by proxy repository upstream servers. Any user with read access to a proxy repository backed by an attacker-controlled or compromised upstream server — including an anonymous user, if anonymous access is enabled — could receive a response from an internal network address or cloud metadata endpoint as repository content, potentially exposing sensitive information such as cloud IAM credentials.

Nexus Repository 3 is vulnerable to Server-Side Request Forgery (SSRF) via the SSL Certificate Retrieval endpoint. A user holding the nexus:ssl-truststore:read permission could cause the server to initiate outbound connections to internal or otherwise restricted network hosts. This issue affects Nexus Repository 3.0.0 through versions prior to 3.94.0.

A vulnerability in Sonatype Nexus Repository Manager's format-specific API key generation may allow a remote attacker to gain unauthorized access to repository operations as a targeted user. A format-specific API key realm (NuGet API Key, Docker Bearer Token, or npm Bearer Token) must be enabled and the targeted user must have an active API key for this vulnerability to be exploitable.
