Descriptions

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access.

En PHP versiones 7.2.x por debajo de 7.2.26, versiones 7.3.x por debajo de 7.3.13 y 7.4.0, la clase DirectoryIterator de PHP acepta nombres de archivo con \0 byte insertado y los trata como terminando en ese byte. Esto podría conllevar a vulnerabilidades de seguridad, por ejemplo en aplicaciones que comprueban las rutas a las que se permite acceder al código.
