CVE-2025-20015 is a medium-severity vulnerability affecting Intel(R) Ethernet Connection software versions prior to 29.4. The vulnerability arises from an uncontrolled search path element, which can be exploited by an authenticated user with local access to escalate privileges on the affected system. Specifically, the software improperly handles the search path for certain components or libraries, allowing a malicious actor to influence the loading of executable code or libraries by placing a crafted file in a location that the software searches before the legitimate one. This can lead to execution of arbitrary code with elevated privileges. The vulnerability requires the attacker to have at least low-level privileges (authenticated user with local access), and user interaction is also necessary, which limits remote exploitation. The CVSS 4.0 vector indicates a local attack vector (AV:L), high attack complexity (AC:H), privileges required are low (PR:L), and user interaction is required (UI:A). The impact on confidentiality, integrity, and availability is high, meaning successful exploitation could allow full control over the affected system. No known exploits are currently reported in the wild, and no patches or mitigation links are provided in the source information, indicating that organizations should proactively seek updates or mitigations from Intel. The vulnerability does not affect network-facing components directly but can be leveraged by insiders or attackers who have gained limited access to escalate privileges further.

For European organizations, this vulnerability poses a significant risk particularly in environments where Intel Ethernet Connection software is widely deployed, such as enterprise networks, data centers, and critical infrastructure. Successful exploitation could allow attackers to gain elevated privileges, potentially leading to unauthorized access to sensitive data, disruption of network communications, or further lateral movement within corporate networks. This is especially concerning for sectors with strict data protection requirements under GDPR, as privilege escalation could facilitate data breaches or sabotage. The requirement for local access and user interaction reduces the risk of widespread remote exploitation but does not eliminate insider threats or attacks following initial compromise. Organizations relying on Intel Ethernet Connection software in their network infrastructure should consider this vulnerability a priority to address to maintain network security and compliance with European cybersecurity regulations.

European organizations should implement the following specific mitigation steps: 1) Immediately inventory and identify all systems running Intel Ethernet Connection software versions prior to 29.4. 2) Coordinate with Intel or authorized vendors to obtain and apply the official software update or patch as soon as it becomes available. 3) Until patches are applied, restrict local access to affected systems by enforcing strict access controls, including limiting administrative privileges and using multi-factor authentication for local logins. 4) Monitor systems for unusual activity indicative of privilege escalation attempts, such as unexpected process launches or modifications to system libraries and executables. 5) Employ application whitelisting and integrity verification tools to detect unauthorized changes in the software search paths or loaded libraries. 6) Educate users about the risks of interacting with untrusted files or software components, as user interaction is required for exploitation. 7) Regularly review and update endpoint security policies to reduce the attack surface and prevent lateral movement following initial compromise.
