Vulnerability CVE-2016-7125
Published: 2016-09-11   Modified: 2016-09-12

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.
