Background
TensorFlow is an open-source machine learning framework that provides a comprehensive ecosystem for building and deploying machine learning models. It includes various tools and libraries for tasks such as data processing, model training, and serving. The 'saved_model_cli' tool is used for interacting with TensorFlow models, allowing users to run inference and manage model versions. However, it has been found to be vulnerable to a code injection attack, which could lead to severe security implications if exploited.
Vulnerability Detail
The vulnerability in TensorFlow's 'saved_model_cli' tool arises from an incomplete fix for a previous vulnerability (CVE-2021-41228). The tool allows users to execute arbitrary code through the 'input_exprs' argument, which can be manipulated to run malicious commands. This can lead to unauthorized access and control over the system, including the ability to open a reverse shell. The vulnerability is particularly concerning as it allows for unsafe execution of code, which could compromise the integrity and confidentiality of the system.
How To Fix
Latest published version: 2.21.0 as of 22 Oct 2026
pip install --upgrade "tensorflow-cpu==2.21.0"Upgrading to it may include breaking changes; the versions below are the minimum fixed release for this vulnerability.
