A security flaw has been discovered in Sony Neural Network Libraries up to 1.39.0. This impacts the function func_set_nnabla_version_decorate of the file python/src/nnabla/utils/converter/utils.py of the component NNP Converter. Performing a manipulation of the argument function.type results in code injection. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.
