CVE-2021-47900 is a critical remote code execution vulnerability affecting Gila CMS versions prior to 2.0.0, allowing unauthenticated attackers to execute arbitrary system commands. Attackers can achieve this by injecting PHP code into the User-Agent HTTP header, which is then processed by the admin endpoint. With a CVSS score of 9.8, this vulnerability 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 or public exploit code (Metasploit, Nuclei, ExploitDB) has been identified, and community discussion is minimal, its high FAUCET Risk Score of 95/100 indicates significant potential impact.
