Name of the Vulnerable Software and Affected Versions NVIDIA Spatial Intelligence Lab's (SIL) GEN3C (affected versions not specified)

Description The inference API server contains an unauthenticated remote code execution flaw. The endpoints '/request-inference' and '/seed-model' deserialize raw HTTP request bodies using the Python pickle.loads() function without requiring authentication or performing input validation. An attacker can send a crafted payload containing a reduce gadget to the inference API port to execute arbitrary code with the privileges of the inference process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
