Executive Summary

This vulnerability exists in the AMD Auto Updater application because it uses insecure HTTP transport without digital signature verification.

This flaw allows a remote attacker to perform a man-in-the-middle (MITM) attack, where the attacker can intercept and modify communications.

Through this attack, the attacker could introduce a malicious executable, potentially leading to arbitrary or elevated code execution on the affected system.

Detection Guidance

Detection of this vulnerability involves identifying the use of insecure HTTP transport by affected AMD tools such as AMD Management Console, AMD Ryzen Master, and AMD µProf.

You can monitor network traffic for unencrypted HTTP connections initiated by these applications, which may indicate exposure to the vulnerability.

• Use network monitoring tools like Wireshark or tcpdump to capture traffic and filter for HTTP requests from the affected applications.
• Example tcpdump command to capture HTTP traffic on port 80: sudo tcpdump -i any tcp port 80 and host <target-ip>
• Check running versions of the affected software to identify if they are outdated and vulnerable, for example, by querying installed package versions or application about dialogs.

Mitigation Strategies

The immediate mitigation step is to update the affected AMD software to the fixed versions released by AMD.

• Update AMD Management Console to version 14.0.0 or later.
• Update AMD Ryzen Master to version 2.14.3 or later.
• Update AMD µProf to version 5.3 or later.

These updates address the insecure HTTP transport issue and prevent potential man-in-the-middle attacks leading to arbitrary code execution.
