CVE-2015-0249
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 · uneditedThe weblog page template in Apache Roller 5.1 through 5.1.1 allows remote authenticated users with admin privileges for a weblog to execute arbitrary Java code via crafted Velocity Text Language (aka VTL).
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 confidenceApache Roller 5.1 through 5.1.1 contains a server-side template injection vulnerability in its weblog page template system. Authenticated users with admin privileges for a weblog can inject and execute arbitrary Java code by crafting malicious Velocity Text Language (VTL) expressions within template files.

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 Apache Roller installation and versionCheck the Roller application version by reviewing the deployed WAR file name, pom.xml if source is available, or the admin UI 'About' page typically found at /roller-ui/admin/about.rolAffected if The installed version is 5.1.0 or 5.1.1
-
Confirm template editing is accessibleLog in as a weblog administrator and navigate to the Weblog > Templates section. Verify that the ability to create or edit page templates is available.Affected if The template editing feature is enabled and accessible to weblog admins
-
Check for unauthorized template modificationsReview template files in the Weblog > Templates section for any unexpected or suspicious VTL expressions such as '#set', '#foreach', or '#evaluate statements that were not authored by trusted admins.Affected if Templates contain unrecognized VTL directives or code that was not intentionally added by your administrators
-
Audit user accounts with admin privilegesReview the Roller user administration panel to list all users granted weblog admin or system admin permissions, particularly any unexpected or newly created accounts.Affected if There are admin accounts that were not created by known, trusted administrators
You are affected if Apache Roller version 5.1.0 or 5.1.1 is running and the template editing feature is accessible to authenticated weblog administrators.

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 to Apache Roller 5.1.2 or later which patches this vulnerability. Until upgraded, restrict template editing permissions to only highly trusted administrators and monitor for unauthorized template modifications.
