Descriptions

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.

PHP en versiones anteriores a 5.4.40, 5.5.x en versiones anteriores a 5.5.24 y 5.6.x en versiones anteriores a 5.6.8 no asegura que los nombres de ruta carezcan de la secuencia %00, lo que podría permitir a atacantes remotos leer o escribir archivos arbitrarios a través de entrada manipulada para una aplicación que llama a (1) un método de carga DOMDocument, (2) la función xmlwriter_open_uri, (3) la función finfo_file o (4) la función hash_hmac_file, según lo demostrado mediante un ataque filename\0.xml que elude una configuración prevista en la que los usuarios cliente pueden leer solamente archivos .xml.

It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions.
