PHP Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') Vulnerability (CVE-2016-7125)
Description
ext/session/session.c in PHP before 5.6.25 and 7.x before 7.0.10 skips invalid session names in a way that triggers incorrect parsing, which allows remote attackers to inject arbitrary-type session data by leveraging control of a session name, as demonstrated by object injection.
