CVE-2023-39539 is a high-severity vulnerability in AMI AptioV BIOS firmware that allows a local user with high privileges to upload a malicious PNG logo file due to improper input validation. Exploiting this flaw can lead to complete compromise of confidentiality, integrity, and availability of the affected system. The vulnerability requires local access, high privileges, and no user interaction, but has a scope that can affect the entire system firmware. There are no known exploits in the wild yet, and no patches have been released at the time of publication. European organizations using systems with AMI AptioV BIOS, especially version BKS_5.0, are at risk, particularly in sectors with high-value targets such as finance, government, and critical infrastructure. Mitigation involves restricting local access, monitoring BIOS update processes, and applying vendor patches once available. Countries with significant deployments of affected hardware and strategic importance in technology and infrastructure are more likely to be targeted. The CVSS score of 7.5 reflects the high impact and complexity of exploitation, emphasizing the need for prompt attention.
