What is CVE-2017-7189?
CVE-2017-7189 is a high-severity vulnerability in Php Php, published on 10 Jul 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
main/streams/xp_socket.c in PHP 7.x before 2017-03-07 misparses fsockopen calls, such as by interpreting fsockopen('127.0.0.1:80', 443) as if the address/port were 127.0.0.1:80:443, which is later truncated to 127.0.0.1:80. This behavior has a security risk if the explicitly provided port number (i.e., 443 in this example) is hardcoded into an application as a security policy, but the hostname argument (i.e., 127.0.0.1:80 in this example) is obtained from untrusted input.
