Am I affected by the Intel AMT/ISM/SBT escalation of privilege vulnerability?

Summary

– The Intel AMT/ISM/SBT escalation of privilege vulnerability affects devices with these features enabled.
– Users can check if their device is affected and take steps to mitigate the risk.

Introduction

– The Intel Active Management Technology (AMT), Intelligent Platform Management Interface (IPMI), and Small Business Technology (SBT) are features that allow remote management of devices. However, these features also come with a security risk due to an escalation of privilege vulnerability that was discovered in 2017. This vulnerability allows an attacker to gain unauthorized access to the device’s administration functions and potentially take control of the entire system.
– Am I affected?
– The first step to determine if your device is affected by this vulnerability is to check if it has AMT, IPMI, or SBT enabled. Most devices with these features will have a sticker indicating their presence on the motherboard. If you are unsure, you can consult the manufacturer’s documentation or contact customer support for assistance.
– If your device does have one of these features enabled, it is possible that it is affected by the vulnerability. However, not all devices with AMT/IPMI/SBT enabled are vulnerable. The specific version of the firmware and BIOS on your device determines if you are at risk. You can check the current firmware and BIOS versions by accessing the device’s management interface or consulting the manufacturer’s documentation.
– If your device is affected, the next step is to determine the severity of the vulnerability. This will depend on how the device is used and the security measures that are in place. For example, if the device is only used within a private network with restricted access, the risk may be lower than for a device connected to the internet or used by multiple users.
– Mitigation steps
– If you determine that your device is affected by the Intel AMT/ISM/SBT escalation of privilege vulnerability, there are several steps you can take to mitigate the risk:
– Disable AMT/IPMI/SBT: If possible, disable these features on your device. This will eliminate the risk of an attacker exploiting the vulnerability.
– Update firmware and BIOS: Check for updates to the firmware and BIOS on your device. Manufacturers have released patches to address this vulnerability, so updating to the latest version can help protect against the risk.
– Use strong passwords: Ensure that all administration passwords on your device are strong and unique. This will make it more difficult for an attacker to gain access to the device’s management interface.
– Limit access: Restrict access to the device’s management interface to authorized users only. This can be achieved through firewall rules or by using a VPN connection.
– Monitor activity: Regularly monitor the device’s event logs and system activity for any unusual behavior. This can help detect if an attacker has gained unauthorized access to the device.

Conclusion

– The Intel AMT/ISM/SBT escalation of privilege vulnerability is a serious security risk that affects devices with these features enabled. However, by taking steps to determine if your device is affected and implementing mitigation measures, you can protect against the risk of an attacker exploiting this vulnerability. It is important to stay informed about security updates and patches for your device and to regularly review your security practices to ensure that they remain effective.
