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 powermail extension is installedAccess TYPO3 backend, navigate to Extension Manager or Extension List, search for 'powermail' or 'Powermail', confirm the extension is installed and loaded.Affected if powermail extension is present in the TYPO3 installation
-
Check installed powermail versionIn TYPO3 Extension Manager, view the details of the powermail extension to find the installed version number. Alternatively, check the version in the file ext_emconf.php in the powermail extension directory.Affected if version is 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6, 2.0.7, 2.0.8, 2.0.9, or 2.0.10
-
Confirm CAPTCHA is enabled in powermail configurationNavigate to the powermail plugin settings in TYPO3 backend. Check the form or plugin configuration for CAPTCHA settings, typically found in the plugin content element or flexform settings for the powermail form.Affected if CAPTCHA protection is activated for any powermail form in the installation
-
Identify forms using CAPTCHA protectionReview all powermail form configurations in the TYPO3 backend. Look for forms that have CAPTCHA or security image validation enabled in their flexform or plugin settings.Affected if any powermail forms are configured to use CAPTCHA validation
The environment is affected if powermail extension version 2.0.0 through 2.0.10 is installed AND CAPTCHA protection is enabled on any powermail form, allowing attackers to bypass the CAPTCHA validation.
