Descriptions

The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3 does not prevent directory traversal, which allows attackers to bypass a deserialization protection mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL.

El paquete PharStreamWrapper (también conocido como phar-stream-wrapper), versiones 2.x anteriores a 2.1.1 y 3.x anteriores a 3.1.1 para TYPO3, no impide el salto de directorio, lo que permite a los atacantes eludir un mecanismo de protección de deserialización, como lo demuestra una URL phar:///path/bad.phar/../good.phar.
