Описание
Python-Multipart is a streaming multipart parser for Python. Versions prior to 0.0.26 have a denial of service vulnerability when parsing crafted multipart/form-data requests with large preamble or epilogue sections. Upgrade to version 0.0.26 or later, which skips ahead to the next boundary candidate when processing leading CR/LF data and immediately discards epilogue data after the closing boundary.
A flaw was found in Python-Multipart, a tool for processing web form data. A remote attacker could exploit this vulnerability by sending specially crafted web requests. These requests, containing unusually large sections of data before or after the main content, could cause the system to become unresponsive. This leads to a denial of service, preventing legitimate users from accessing the service.
Меры по смягчению последствий
To mitigate this issue, restrict network access to services utilizing python-multipart to trusted clients only. Implement rate limiting and robust input validation at the application or network level to filter out malformed multipart/form-data requests before they reach the vulnerable component. This can help prevent the service from becoming unresponsive due to specially crafted requests.
