29
FAUCET Score

CVE-2019-16700 is a critical vulnerability affecting the slub_events extension (versions through 3.0.2) for TYPO3, and specifically the slub_dresden and slub_events products. It allows unauthenticated attackers to upload arbitrary files to the webserver. This flaw carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. For versions 1.2.2 and below, this leads to Remote Code Execution, while newer versions face Denial of Service by filling the web space. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
