CVE-2016-7125: 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...

Security readout for executives and security teams

This is a PHP session-handling flaw in older PHP 5.6 and 7.0 releases. If an attacker can influence a session name, PHP may parse session data incorrectly and allow injected session content, including object-injection scenarios. This mainly matters for legacy PHP applications still running unpatched runtimes. Exposure is most likely in legacy PHP 5.6 or early 7.0 applications using PHP sessions, especially where request-controlled data can affect session naming. Modern supported PHP versions should not be affected by the versions named in the CVE. Prioritize remediation if any internet-facing service still runs the affected PHP versions. The issue is old, but unpatched legacy PHP creates broader operational risk beyond this CVE. Mitigation focus: Upgrade PHP to 5.6.25, 7.0.10, or a supported newer release.; Apply relevant distribution advisories, including Gentoo or Red Hat packages where applicable.; Review application logic that lets requests influence PHP session names..
