CVE-2016-9492

25
FAUCET Score

CVE-2016-9492 describes an unrestricted file upload vulnerability in PHP FormMail Generator versions prior to December 17, 2016. The generated form.lib.php file uses an incomplete blacklist of dangerous file extensions, allowing attackers to upload and execute PHP code by exploiting variations not included in the list. This critical vulnerability has a CVSS score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it can be exploited remotely with low complexity, leading to complete compromise of confidentiality, integrity, and availability. While there is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion, the high FAUCET Risk Score of 79/100 suggests its potential impact.
