CVE-2010-4957
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 Questionnaire (ke_questionnaire) extension before 2.2.3 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 ke_questionnaire TYPO3 extension allows remote attackers to execute arbitrary SQL commands through unsanitized input. The vulnerability exists in versions prior to 2.2.3 and is exploitable without authentication given the CVSS vector indicates network-level attack.

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 ke_questionnaire extension is installedIn TYPO3 backend, navigate to Extension Manager or check typo3conf/ext/ directory for ke_questionnaire folderAffected if The ke_questionnaire extension folder exists in the TYPO3 installation
-
Determine installed ke_questionnaire versionCheck the ext_emconf.php or composer.json file within the ke_questionnaire extension directory for the version numberAffected if Version is 2.2.2 or lower, or specifically 1.2.1 or 2.0.0
-
Confirm extension is enabledCheck TYPO3 backend extension list or LocalConfiguration.php to verify the extension is loaded and activeAffected if Extension is installed and actively loaded in the TYPO3 instance
-
Check for public-facing questionnaire formsInspect the website frontend for any pages rendering ke_questionnaire survey or questionnaire functionalityAffected if Questionnaire forms are publicly accessible without authentication
A TYPO3 instance is affected if ke_questionnaire extension versions 2.2.2 or lower (including 1.2.1 and 2.0.0) are installed and enabled, exposing SQL injection risk to unauthenticated network attackers.
