Overview
CVE-2023-41100 affects the hcaptcha (also known as hCaptcha for EXT:form) extension before version 2.1.2 for TYPO3. The vulnerability was discovered and disclosed in August 2023, impacting the CAPTCHA validation functionality of the extension (TYPO3 Advisory).
Technical details
The vulnerability stems from a broken access control issue where the extension fails to properly validate the requirement of the CAPTCHA field in submitted form data. This implementation flaw has been assigned a CVSS v3.1 base score of 5.3 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N (NVD).
Impact
The vulnerability allows remote users to bypass the CAPTCHA verification mechanism entirely, potentially enabling automated form submissions and compromising the security measures intended to prevent automated abuse (TYPO3 Advisory).
Mitigation and workarounds
The vulnerability has been fixed in version 2.1.2 of the hcaptcha extension. Users are strongly advised to update to this version as soon as possible. The update is available through the TYPO3 extension manager, packagist, and can be downloaded directly from the TYPO3 extension repository (TYPO3 Advisory).
