Descriptions

ReportLab through 3.5.26 allows remote code execution because of toColor(eval(arg)) in colors.py, as demonstrated by a crafted XML document with '<span color="' followed by arbitrary Python code.

ReportLab versiones hasta 3.5.26, permite la ejecución de código remota debido a la función toColor(eval(arg)) en el archivo colors.py, como es demostrado por un documento XML diseñado con '(span color ="' seguido de un código arbitrario de Python.

A code injection vulnerability in python-reportlab allows an attacker to execute code while parsing a color attribute. An application that uses python-reportlab to parse untrusted input files may be vulnerable to this flaw and allow remote code execution.

It was discovered that python-reportlab, a Python library to create PDF documents, is prone to a code injection vulnerability while parsing a color attribute. An attacker can take advantage of this flaw to execute arbitrary code if a specially crafted document is processed.
