PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read arbitrary files via crafted input to an application that calls the stream_resolve_include_path function in ext/standard/streamsfuncs.c, as demonstrated by a filename\0.extension attack that bypasses an intended configuration in which client users may read files with only one specific extension.

Security readout for executives and security teams

CVE-2015-3412 is a legacy PHP file-handling flaw. A vulnerable PHP application that accepts user-influenced filenames may fail to reject %00 path sequences, letting an attacker bypass intended extension restrictions and read files the application should not expose. Exposure is most likely in unsupported or vendor-maintained legacy PHP 5.4, 5.5, or 5.6 deployments, especially custom applications that resolve include paths from request-controlled filenames. Modern PHP branches are not identified as affected in the source bundle. Treat this as a targeted legacy-platform risk. It is not marked actively exploited, but systems still running affected PHP versions may expose sensitive files through vulnerable application patterns. Prioritize internet-facing and data-sensitive PHP services first. Mitigation focus: Upgrade PHP to 5.4.40, 5.5.24, 5.6.8, or a vendor-fixed package.; Prioritize replacing unsupported PHP 5.x runtimes with supported versions.; Review vendor advisories from Red Hat, Oracle, and PHP for package-specific guidance..
