CVE-2013-7394
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 "runshellscript echo.sh" script in Splunk before 5.0.5 allows remote authenticated users to execute arbitrary commands via a crafted string. NOTE: this issue was SPLIT from CVE-2013-6771 per ADT2 due to different vulnerability types.

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.
-
Check installed Splunk versionRun 'splunk --version' from the command line, or log into the Splunk web interface and navigate to Settings > About > General information to view the exact version numberAffected if The installed version is 5.0, 5.0.1, 5.0.2, 5.0.3, or 5.0.4 (any version prior to 5.0.5)
-
Verify runshellscript functionality is accessibleCheck if the runshellscript command is available by searching for 'runshellscript' in Splunk's configuration files (local/app.conf) or by attempting to access it via the Splunk REST API endpoint '/services/admin/runshellscript'Affected if The runshellscript endpoint responds without authentication failure or is explicitly enabled in the configuration
-
Confirm Splunk authentication is in useReview Splunk's authentication settings in $SPLUNK_HOME/etc/system/local/authentication.conf or via the web interface under Settings > Authentication methodAffected if Splunk is configured to allow user authentication (rather than being disabled entirely) and unauthenticated access to the runshellscript endpoint is possible
You are affected if your Splunk installation version is 5.0 through 5.0.4 and the runshellscript functionality is accessible to authenticated users via the API or web interface.

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.
dbcve · scopedUpgrade to Splunk 5.0.5 or later to patch the vulnerability. Additionally, limit Splunk user access to only trusted personnel and implement network segmentation to reduce exposure of the Splunk interface.
Splunk Enterprise 5.0.5 or later
- 1. Backup your Splunk configuration and data directories before upgrading
- 2. Download Splunk Enterprise 5.0.5 or later from the official Splunk website (www.splunk.com)
- 3. Stop the Splunk service using: ./splunk stop
- 4. Install the upgraded version, preserving existing configurations
- 5. Start the Splunk service using: ./splunk start
- 6. Verify the upgrade was successful by logging into the Splunk web interface
- 7. Confirm the runshellscript echo.sh functionality no longer accepts arbitrary command strings
