CVE-2007-4850: curl/interface.c in the cURL library (aka libcurl) in PHP 5.2.4 and 5.2.5 allows context-dependent attacker...

Security readout for executives and security teams

This flaw affects legacy PHP 5.2.4 and 5.2.5 use of libcurl. In some contexts, an attacker could bypass PHP safe_mode and open_basedir file restrictions and read files the application was meant to block. Business risk is mainly for unsupported legacy PHP systems that still process attacker-controlled cURL requests. Exposure is most likely in old PHP 5.2.4 or 5.2.5 deployments, especially shared-hosting or legacy applications relying on safe_mode/open_basedir for containment. Modern supported PHP stacks are unlikely to be affected, but stale appliances, abandoned apps, or frozen server images should be checked. Prioritize this when legacy PHP 5.2.x exists in production or regulated environments. If no PHP 5.2.4 or 5.2.5 remains, business urgency is low. Unsupported PHP should still be retired because this issue is one of many unresolved legacy risks. Mitigation focus: Identify and remove PHP 5.2.4 or 5.2.5 from production systems.; Upgrade PHP using vendor-supported packages or current supported PHP releases.; Review Ubuntu, Apple, Mandriva, rPath, and PHP guidance for patched package status..
