# Insecure deserialization in BentoML

BentoML, a Python framework for serving machine learning models, deserializes attacker-supplied objects in requests sent to any valid endpoint. A crafted serialized object runs operating system commands on the server when it is deserialized.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- pypi:bentoml affected < 1.2.5 fixed 1.2.5

## How to check

- Run `pip show bentoml` and check whether the version is below `1.2.5`
- Search the lockfiles and requirements for `bentoml` pinned below `1.2.5`

## Fix

- Upgrade the `bentoml` package to `1.2.5` or later
- Redeploy any BentoML service images or containers after upgrading

## From the sources

An insecure deserialization vulnerability exists in the BentoML framework, allowing remote code execution (RCE) by sending a specially crafted POST request. By exploiting this vulnerability, attackers can execute arbitrary commands on the server hosting the BentoML application. The vulnerability is triggered when a serialized object, crafted to execute OS commands upon deserialization, is sent to any valid BentoML endpoint. This issue poses a significant security risk, enabling attackers to compromise the server and potentially gain unauthorized access or control.
