CVE-2025-26470 is a vulnerability identified in Intel(R) Distribution for Python software installers prior to version 2025.1.0. The root cause is incorrect default permissions set on certain installer components, which can be exploited by an authenticated user with local access to escalate their privileges on the affected system. The vulnerability does not require remote access but does require the attacker to have some level of authenticated local access and user interaction, making exploitation more complex. 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 rated high, meaning successful exploitation could lead to significant compromise of system security. No known public exploits have been reported yet, but the vulnerability is publicly disclosed and patched in version 2025.1.0 of the Intel Distribution for Python installers. This distribution is commonly used in enterprise and scientific computing environments where Intel-optimized Python packages are preferred. The vulnerability could allow an attacker to gain elevated privileges, potentially leading to unauthorized access to sensitive data or system control. The issue stems from insecure file permissions that could be modified or leveraged by a local attacker to escalate privileges beyond their intended scope.

The vulnerability poses a moderate risk to organizations using affected versions of Intel Distribution for Python installers. Successful exploitation could allow an authenticated local user to escalate privileges, potentially gaining administrative or root-level access. This could lead to unauthorized access to sensitive data, modification or deletion of critical files, installation of persistent malware, or disruption of services. Since the attack requires local access and user interaction, the threat is more relevant in environments where multiple users share systems or where attackers can gain initial foothold through other means. Organizations with development, research, or production environments relying on Intel-optimized Python distributions are at risk. The impact extends to confidentiality, integrity, and availability of affected systems, potentially compromising enterprise operations, intellectual property, and data privacy. Although no exploits are currently known in the wild, the public disclosure increases the risk of future exploitation attempts, especially in targeted attacks against organizations using Intel's Python distribution.

To mitigate this vulnerability, organizations should immediately upgrade Intel Distribution for Python installers to version 2025.1.0 or later, where the permission issues have been corrected. Until patching is possible, administrators should audit and manually correct file and directory permissions associated with the installer to ensure they do not allow unauthorized modification or execution by low-privileged users. Implement strict access controls on systems where Intel Python distributions are installed, limiting local user privileges and restricting who can execute or modify installer files. Employ endpoint protection solutions that monitor for unusual privilege escalation attempts. Additionally, enforce the principle of least privilege for all users and services, and segment systems to reduce the risk of lateral movement if an attacker gains local access. Regularly review system logs for signs of privilege escalation attempts and educate users about the risks of executing untrusted code or installers. Finally, maintain an up-to-date inventory of software versions to quickly identify and remediate vulnerable installations.
