CVE-2019-16699 describes a critical remote code execution vulnerability affecting the sr_freecap (freeCap CAPTCHA) extension for TYPO3, specifically versions 2.4.5 and below, and 2.5.2 and below. This flaw stems from insufficient sanitization of user input, enabling attackers to execute arbitrary Extbase actions. With a CVSS score of 9.8 (CRITICAL), this vulnerability is easily exploitable over the network without authentication or user interaction, leading to complete compromise of confidentiality, integrity, and availability. While no active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB) has been identified, and community discussion is minimal, its high severity and ease of exploitation warrant immediate patching.
