SSRF Vulnerability in PHP fsockopen and pfsockopen

CVE-2017-7272 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:N

PHP through 7.1.11 enables potential SSRF in applications that accept an fsockopen or pfsockopen hostname argument with an expectation that the port number is constrained. Because a :port syntax is recognized, fsockopen will use the port number that is specified in the hostname argument, instead of the port number in the second argument of the function.
