CVE-2023-3533 is a critical path traversal vulnerability affecting Chamilo LMS versions up to and including 1.11.20, specifically within the file upload functionality of /main/webservices/additional_webservices.php. This flaw allows unauthenticated attackers to achieve stored cross-site scripting and remote code execution through arbitrary file writes. With a CVSS score of 9.8 (Critical), it presents a severe risk due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the high FAUCET Risk Score of 84/100 indicates its potential severity.
