Executive brief
NVIDIA Megatron Bridge, a tool used for bridging large-scale machine learning models, contains a security flaw that could allow an attacker to take control of a system. By tricking a user into processing a malicious file, an attacker could execute unauthorized commands, steal sensitive data, or modify system information. This could lead to a total compromise of the workstation or server where the software is running.
Technical details
NVIDIA Megatron Bridge for Linux (versions 0.0 through 0.4.0) is vulnerable to the deserialization of untrusted data (CWE-502). The flaw exists because the application does not sufficiently validate or sanitize input before deserializing it, allowing an attacker to inject malicious objects. Exploitation requires local access and user interaction, such as convincing a user to open a specially crafted file. A successful exploit can result in arbitrary code execution, escalation of privileges, data tampering, and unauthorized information disclosure.
