CVE-2025-54519 is a DLL hijacking vulnerability classified under CWE-427 (Uncontrolled Search Path Element) affecting the AMD Vivado™ Documentation Navigator Installation on Windows platforms. The vulnerability occurs because the software improperly handles the search path for DLLs, allowing an attacker to place a malicious DLL in a location that the application will load instead of the legitimate one. This can be exploited by a local attacker with limited privileges (PR:L) who can trick the user into interacting with the vulnerable component (UI:R). Successful exploitation leads to privilege escalation, enabling the attacker to execute arbitrary code with elevated privileges. The vulnerability impacts confidentiality, integrity, and availability (all rated high), as the attacker could gain control over the system or sensitive data. The CVSS 3.1 vector is AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H, indicating local attack vector, low complexity, required privileges, user interaction, unchanged scope, and high impact on all security properties. No patches or fixes are planned by AMD, increasing the risk for affected users. Although no known exploits are currently in the wild, the vulnerability's nature and impact make it a significant concern for organizations relying on Vivado™ for FPGA design and documentation tasks on Windows.

The vulnerability allows local attackers to escalate privileges and execute arbitrary code, potentially compromising the entire system. This can lead to unauthorized access to sensitive design files, intellectual property theft, disruption of FPGA development workflows, and potential sabotage of hardware design processes. The high impact on confidentiality, integrity, and availability means attackers could manipulate or destroy critical data, install persistent malware, or disrupt business operations. Organizations using Vivado™ in engineering, manufacturing, or research environments face risks of intellectual property loss and operational downtime. The lack of a planned fix increases exposure, forcing organizations to rely on mitigations or alternative workflows. The requirement for local access limits remote exploitation but insider threats or compromised endpoints remain significant risks.

Since no official patch is planned, organizations should implement strict access controls to limit local user privileges on systems running Vivado™ Documentation Navigator. Employ application whitelisting and restrict write permissions on directories searched for DLLs by the application. Use Windows security features such as Controlled Folder Access and AppLocker to prevent unauthorized DLL loading. Educate users to avoid executing untrusted files or interacting with suspicious prompts related to Vivado™. Consider running the software in isolated environments or virtual machines with limited privileges. Monitor systems for unusual DLL loads or privilege escalation attempts using endpoint detection and response (EDR) tools. Regularly audit and harden Windows search paths and environment variables to prevent DLL hijacking. If feasible, evaluate alternative tools or workflows that do not rely on the vulnerable component. Maintain up-to-date backups to recover from potential compromise.
