Security readout for executives and security teams
CVE-2009-4158 affects the TYPO3 Calendar Base (cal) extension before version 1.2.1. It is a SQL injection issue that could let a remote attacker run database commands. Business risk depends on whether legacy TYPO3 sites still use this extension and expose it publicly. Exposure is likely limited to TYPO3 installations running the Calendar Base (cal) extension below 1.2.1, especially internet-facing legacy sites. Organizations without TYPO3 or without this extension are unlikely to be affected. Prioritize if your organization still runs legacy TYPO3 sites. SQL injection can threaten data confidentiality and integrity. If no TYPO3 Calendar Base extension is present, this CVE should be low operational priority after verification. Mitigation focus: Inventory TYPO3 sites for the Calendar Base (cal) extension.; Upgrade affected cal installations to version 1.2.1 or later.; Review TYPO3 security bulletin TYPO3-SA-2009-019 for vendor guidance..
