CyberRota Analysis

AI-Generated

The vulnerability affects the NetBox Device Type Library within GitHub, allowing unauthenticated contributors to manipulate pickle cache files, leading to arbitrary code execution during testing. This poses significant risks to the confidentiality, integrity, and availability of resources within the GitHub Actions runner or maintainer processes. Organizations utilizing this library should prioritize remediation to mitigate potential exploitation.

Original NVD Description

NetBox Device Type Library is a collection of community-sourced device type definitions for import into NetBox. The validation test harness can deserialize pull-request-controlled tracked pickle cache files through pickle.load in the read_pickle_data function in tests/pickle_operations.py. An unauthenticated contributor can change USE_LOCAL_KNOWN_SLUGS in tests/test_configuration.py and supply a crafted tests/known-modules.pickle or tests/known-racks.pickle file that tests/definitions_test.py loads when pytest runs. Deserialization invokes attacker-controlled object reduction behavior, allowing arbitrary code execution in the GitHub Actions runner or in a maintainer process that runs the tests, with the confidentiality, integrity, and availability of reachable resources at risk. This vulnerability is fixed with commit 1c6f7e2b93589b965318c6e67ac3504831f0e71e.
