Описание
paraparser in ReportLab before 3.5.31 allows remote code execution because start_unichar in paraparser.py evaluates untrusted user input in a unichar element in a crafted XML document with '<unichar code="' followed by arbitrary Python code, a similar issue to CVE-2019-17626.
A code injection vulnerability was found in python-reportlab that may allow an attacker to execute code while parsing a unichar element attribute. An application that uses python-reportlab to parse untrusted input files may be vulnerable and could allow remote code execution.
Отчет
To exploit the issue, a malicious user has to use a crafted malicious html 'unichar' tag input and then use the reportlab's feature to generate a pdf of the document and that can lead to a remote code execution, therefore, this CVE has an Important impact. This vulnerability is similar to CVE-2019-17626.
