CVE-2013-4721
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 · uneditedSQL injection vulnerability in the RSS feed from records extension 1.0.0 and earlier for TYPO3 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.
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 · moderate confidenceSQL injection vulnerability in the RSS feed generator of the 'records' extension for TYPO3 allows remote unauthenticated attackers to inject arbitrary SQL commands through the feed functionality. The vulnerability exists in version 1.0.0 and earlier with unspecified input parameters not being properly sanitized before being used in database queries.

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.
-
Verify the 3ds Push2rss extension is installedCheck TYPO3 extension manager or look for the extension in typo3conf/ext/ directory for a folder named 'push2rss' or similar records-related extensionAffected if The extension is present in the TYPO3 installation
-
Determine the installed extension versionCheck the ext_emconf.php file within the extension directory for the version number, or view extension details in TYPO3 extension managerAffected if The version is 1.0.0 or earlier
-
Confirm RSS feed functionality is enabledLocate the RSS feed generation code or configuration within the extension, typically in a controller or plugin file handling feed requestsAffected if RSS feed generation is active and accessible via web request
-
Test for SQL injection exposureAttempt to access the RSS feed URL endpoint with special characters in parameters (such as single quotes) and observe if SQL errors are returned or behavior changesAffected if The application returns database errors or exhibits unexpected behavior when malformed input is provided
A TYPO3 instance is affected if it has the 3ds Push2rss extension installed at version 1.0.0 or earlier with the RSS feed functionality enabled and accessible.

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 dataUpdate the TYPO3 records extension to a version newer than 1.0.0 that contains the security fix. If no patched version is available, disable the RSS feed functionality or remove the extension entirely until a fix can be applied.
