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 or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument load method, (2) the xmlwriter_open_uri function, (3) the finfo_file function, or (4) the hash_hmac_file function, as demonstrated by a filename\0.xml attack that bypasses an intended configuration in which client users may read only .xml files.

Security readout for executives and security teams

CVE-2015-3411 is a PHP pathname handling flaw. Older PHP releases could fail to block encoded null-byte sequences in filenames, letting a vulnerable application bypass file-extension restrictions and potentially read or write files it should not access. Exposure is most likely in legacy PHP 5.x applications that accept user-controlled filenames or paths and rely on extension checks, especially XML upload, inspection, hashing, or file-writing workflows. Treat this as legacy-risk cleanup with meaningful impact where exposed. It is not marked as actively exploited in the provided sources, but affected PHP versions are obsolete and should be removed from production. Mitigation focus: Upgrade PHP to 5.4.40, 5.5.24, 5.6.8, or later supported vendor builds.; Prioritize replacement of unsupported PHP 5.x runtimes.; Review vendor advisories for distribution-specific fixed packages..
