The session extension in PHP 4 before 4.4.5, and PHP 5 before 5.2.1, calculates the reference count for the session variables without considering the internal pointer from the session globals, which allows context-dependent attackers to execute arbitrary code via a crafted string in the session_register after unsetting HTTP_SESSION_VARS and _SESSION, which destroys the session data Hashtable.

Security readout for executives and security teams

CVE-2007-1700 is a memory-management flaw in PHP's session handling. In affected PHP 4 and PHP 5 versions, crafted session-related input can corrupt session data handling and may allow arbitrary code execution in context-dependent conditions. Exposure is most likely in legacy PHP applications or appliances still running PHP 4 before 4.4.5 or PHP 5 before 5.2.1, especially where application code uses old session APIs and directly manipulates session globals. Prioritize this as a legacy exposure issue with potentially severe impact. The main business risk is forgotten PHP 4 or early PHP 5 systems still reachable in production or bundled inside older appliances. Mitigation focus: Upgrade direct PHP installs to PHP 4.4.5, PHP 5.2.1, or later fixed versions.; Apply vendor PHP security updates from Debian, Gentoo, Ubuntu, SUSE, HP, or the relevant platform vendor.; Identify and retire unsupported legacy PHP runtimes where practical..
