CVE-2017-7272: PHP

High severity, CVSS 7.4. EPSS: 3.5% chance of exploitation in the next 30 days.

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.

Affected products

• PHP PHP: up to and including 7.1.3
