Summary
Sony Neural Network Libraries up to and including 1.39.0 has a flaw in the load_param_in_txt function of python/src/nnabla/utils/cli/encode_decode_param.py. Improper control of code generation (CWE-94) lets manipulated input lead to code injection. A remote attacker without privileges can trigger it, but a user must interact with the attack. A public exploit is available and might be used, and the vendor did not respond to early disclosure.

Description from the CNA
A vulnerability was identified in Sony Neural Network Libraries up to 1.39.0. This affects the function load_param_in_txt of the file python/src/nnabla/utils/cli/encode_decode_param.py of the component Encode Param Command Handler. Such manipulation leads to code injection. It is possible to launch the attack remotely. The exploit is publicly available and might be used. 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.
