CVE-2025-14596 identifies a vulnerability categorized under CWE-427 (Uncontrolled Search Path Element) in the Altera Quartus Prime Pro Installer for Windows platforms, specifically affecting versions from 23.3 through 24.3.1. The vulnerability arises because the installer does not securely control the search path used to locate DLLs or executables during installation, allowing an attacker with local access to place malicious files in directories that are searched before the legitimate ones. This search order hijacking can lead to execution of attacker-controlled code with the privileges of the installer process, which typically runs with limited user rights. The vulnerability requires local access and user interaction, as the user must run the installer or a related process. The CVSS 4.0 vector indicates a local attack vector (AV:L), high attack complexity (AC:H), partial privileges required (PR:L), and user interaction (UI:A). The impact on confidentiality, integrity, and availability is high if exploitation succeeds, but the scope is limited to the local system. No patches or exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly. This vulnerability is particularly relevant for organizations using Quartus Prime Pro for FPGA design and development, as successful exploitation could compromise development environments or lead to supply chain risks if compromised installers are distributed internally.

For European organizations, the impact of CVE-2025-14596 includes potential local code execution or privilege escalation during the installation of Quartus Prime Pro software. This could lead to unauthorized modification of FPGA design environments, insertion of malicious logic designs, or compromise of intellectual property. Given the critical role of FPGA design in telecommunications, automotive, aerospace, and industrial automation sectors prevalent in Europe, exploitation could disrupt development workflows or lead to supply chain contamination. However, the requirement for local access and user interaction limits remote exploitation risks. Organizations with distributed development teams or less controlled endpoint environments face higher risks. The vulnerability could also facilitate lateral movement within networks if attackers gain initial footholds on developer machines. Overall, the threat could impact confidentiality and integrity of design data and availability of development tools, potentially delaying product development and increasing remediation costs.

To mitigate CVE-2025-14596, European organizations should implement the following specific measures: 1) Restrict write permissions on directories included in the DLL and executable search paths to prevent unauthorized file placement. 2) Enforce strict endpoint security policies to limit local user privileges and prevent execution of untrusted installers. 3) Use application whitelisting and code integrity verification to ensure only legitimate Quartus Prime Pro installers and components are executed. 4) Educate users to avoid running installers from untrusted sources and to verify digital signatures before installation. 5) Monitor installation processes for anomalous behavior or unexpected file modifications. 6) Coordinate with Altera (Intel) for timely patch deployment once available and apply updates promptly. 7) Consider isolating FPGA development environments using virtual machines or containers to limit impact of potential exploitation. 8) Conduct regular audits of development workstations to detect unauthorized changes or presence of suspicious files in search paths.
