CVE-2025-34111 is a critical unauthenticated arbitrary file upload vulnerability affecting Tiki Wiki CMS Groupware version 15.1 and earlier. Attackers can exploit the ELFinder component's default connector to upload and execute malicious PHP scripts on the web server due to a lack of file type validation. This vulnerability carries a CVSS score of 9.8 (CRITICAL), indicating a severe risk with no authentication or user interaction required, leading to complete compromise of confidentiality, integrity, and availability. While not yet observed in active exploitation (KEV: No), a Metasploit module exists, and its high EPSS and FAUCET scores suggest a significant likelihood of future exploitation, despite minimal community discussion or media coverage.
