FAUCET Score

CVE-2015-4147 is a type confusion vulnerability in the SoapClient::__call method of PHP versions before 5.4.39, 5.5.23, and 5.6.7, also affecting Apple and Red Hat products. This flaw allows remote attackers to execute arbitrary code by supplying crafted serialized data due to improper verification of the __default_headers parameter. With a CVSS score of 7.5, it is considered highly severe, requiring no authentication and having low attack complexity, potentially leading to partial confidentiality, integrity, and availability compromise. Despite its high FAUCET Risk Score of 97/100, there is no evidence of active exploitation, no known exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
