Description Preview
A vulnerability has been identified in Intel SGX SDK applications compiled for SGX2 enabled processors. The issue stems from improper input validation (CWE-20) that could allow a privileged user to escalate their privileges via local access. This vulnerability, tracked as CVE-2021-0186, affects applications built with Intel SGX SDK that are specifically compiled for processors supporting SGX2 features.
Overview
The vulnerability exists in the Intel Software Guard Extensions (SGX) SDK, which is a set of tools that allows developers to create applications that utilize Intel SGX technology for enhanced security. When applications are compiled for SGX2-enabled processors, they may contain improper input validation mechanisms that fail to properly sanitize or verify input data. A local attacker with certain privileges could exploit this vulnerability to gain elevated privileges on the affected system. The impact is limited to local attacks and requires the attacker to already have some level of access to the system.
Remediation
To address this vulnerability, system administrators and developers should:
- Update the Intel SGX SDK to the latest version as recommended in the Intel security advisory (intel-sa-00548).
- Recompile SGX applications using the updated SDK.
- Apply any firmware or microcode updates provided by Intel for affected processors.
- Implement proper access controls to limit local access to systems running SGX applications.
- Monitor systems for suspicious activities that might indicate exploitation attempts.
