CVE-2014-2034
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnspecified vulnerability in Sonatype Nexus OSS and Pro 2.4.0 through 2.7.1 allows attackers to create arbitrary user accounts via unknown vectors related to "an unauthenticated execution path."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn authentication bypass vulnerability in Sonatype Nexus OSS and Pro versions 2.4.0 through 2.7.1 allows unauthenticated attackers to create arbitrary user accounts by exploiting an unspecified execution path. This grants attackers the ability to create administrative or privileged accounts without any valid credentials, effectively giving them full control over the Nexus repository manager.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Nexus versionAccess the Nexus web interface and navigate to 'Administration' > 'Server' to view the version, or check the nexus.log file for version information at <nexus-home>/logs/nexus.logAffected if Version is 2.4.0, 2.5.0, 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 2.6.5, 2.7.0, or 2.7.1
-
Compare version to affected rangeVerify the installed version against the affected range 2.4.0 through 2.7.1 inclusiveAffected if Installed version falls within 2.4.0 to 2.7.1
-
Check Nexus web interface network exposureDetermine if the Nexus web application is accessible from untrusted networks by reviewing firewall rules, reverse proxy configuration, or networkACLs allowing access to the default port 8081Affected if Port 8081 or the configured Nexus web port is accessible from untrusted network segments without authentication barriers
-
Review user accounts for unauthorized administrative usersLog into Nexus as an administrator and navigate to 'Administration' > 'Users' to examine all accounts, particularly looking for newly created users with Administrator or privileged roles that were not intentionally createdAffected if Unexpected user accounts with administrative or privileged roles exist in the system
The environment is affected if Nexus version is between 2.4.0 and 2.7.1 and the web interface is network-accessible to unauthenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Nexus to version 2.7.2 or later to patch the unauthenticated user creation vulnerability. If immediate patching is not possible, restrict network access to the Nexus interface using firewall rules or VPN to limit exposure to unauthenticated attackers.
