CVE-2014-9044
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 · uneditedAsset Pipeline in ownCloud 7.x before 7.0.3 uses an MD5 hash of the absolute file paths of the original CSS and JS files as the name of the concatenated file, which allows remote attackers to obtain sensitive information via a brute force attack.
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 confidenceThe asset pipeline in ownCloud 7.x before 7.0.3 generates filenames for concatenated CSS and JS files by using an MD5 hash of the absolute file paths. Since MD5 is cryptographically weak and the original file paths can be brute-forced, an attacker can potentially discover sensitive server path information.

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 ownCloud versionLocate and read the version.php file in the ownCloud installation directory (typically at /var/www/owncloud/version.php or similar path). Alternatively, check the config/config.php file for version information, or run: grep -r 'version' /path/to/owncloud/version.php 2>/dev/nullAffected if The installed version is 7.0.0, 7.0.1, or 7.0.2
-
Confirm asset pipeline is in useExamine the ownCloud configuration file (config/config.php) for asset pipeline settings. Look for parameters related to asset compilation, CSS/JS concatenation, or the asset pipeline feature. Check if the ownCloud instance serves concatenated CSS/JS files.Affected if The asset pipeline feature is enabled and the server concatenates CSS/JS files using the older mechanism
-
Inspect generated asset filenamesVisit a page on the ownCloud instance and view the HTML source. Look for references to CSS or JS files with long alphanumeric filenames (32-character strings, which indicate MD5 hashes). Example: look for href attributes containing strings like 'core/js/abc123...'.Affected if The generated filenames are 32-character MD5 hashes derived from file paths
You are affected if running ownCloud Server version 7.0.0, 7.0.1, or 7.0.2 with the asset pipeline enabled and serving concatenated CSS/JS files that use MD5-based filenames.

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 ownCloud 7.0.3 or later, which implements a more secure filename generation mechanism for the asset pipeline.
