What is CVE-2022-38787?
The CVE-2022-38787 vulnerability involves a lack of proper input validation in the firmware of specific Intel(R) FPGA products, presenting a security risk that could be exploited by an authenticated user to elevate their privileges locally.
The Impact of CVE-2022-38787
The impact of CVE-2022-38787 is rated as MEDIUM severity according to the CVSS v3.1 base score of 5.7. The vulnerability could lead to confidentiality and integrity breaches within affected systems, although the attack vector is limited to local access.
Technical Details of CVE-2022-38787
The technical details of CVE-2022-38787 include:
Vulnerability Description
The vulnerability stems from improper input validation within the firmware of Intel(R) FPGA products, specifically those versions preceding 2.7.0 Hotfix. This flaw allows an authenticated user to potentially escalate their privileges through local exploitation.
Affected Systems and Versions
The affected systems include Intel(R) FPGA products prior to version 2.7.0 Hotfix. Systems running these versions are at risk of exploitation by authenticated users seeking to elevate their privileges.
Exploitation Mechanism
The exploitation of CVE-2022-38787 requires an authenticated user to have local access to the vulnerable Intel(R) FPGA products. By leveraging the lack of input validation, an attacker could potentially escalate their privileges within the system.
Mitigation and Prevention
To mitigate the risks associated with CVE-2022-38787, consider the following steps:
Immediate Steps to Take
Immediately apply security patches and updates provided by Intel to address the vulnerability in affected FPGA products. Restrict access to privileged accounts and closely monitor systems for any suspicious activity.
Long-Term Security Practices
Incorporate regular security assessments and code reviews into your development processes to catch and remediate similar vulnerabilities early in the lifecycle. Enforce the principle of least privilege to limit user capabilities and reduce the impact of potential privilege escalation.
Patching and Updates
Stay informed about security advisories and updates from Intel to ensure timely application of patches for vulnerable FPGA products. Regularly review and update security measures to maintain a robust defense against exploitation.
