Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-8432 is an Incorrect Default Permissions vulnerability, tracked under CWE-276, that affects the MBI modules within Centreon Infra Monitoring. It permits the CentreonBI user account on the MBI server to embed scripts within scripts. The flaw impacts versions 24.10.0 before 24.10.6, 24.04.0 before 24.04.9, and 23.10.0 before 23.10.15, and carries a CVSS 3.1 score of 8.4.

An attacker with high privileges who can authenticate as the CentreonBI account may leverage the permission misconfiguration to inject and execute arbitrary scripts. Because the vulnerability is network-reachable with low attack complexity and requires user interaction, successful exploitation can result in full compromise of confidentiality, integrity, and availability on the affected server with changed scope.

Centreon has published fixes in the referenced releases and corresponding security bulletin, directing administrators to upgrade the affected Infra Monitoring versions to 24.10.6, 24.04.9, or 23.10.15 or later. The associated GitHub release notes provide the updated packages.

EPSS scores for this CVE remain low, with a current value of 0.0103 and a peak of 0.0107.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.

AC-6 Least Privilege good match

Requires least-privilege defaults so that installed files are not world-writable by default.

CM-6 Configuration Settings good match

Requires documented, restrictive configuration settings that cover file and directory permissions.

CM-5 Access Restrictions for Change partial match

Enforces access restrictions on changes, including permission settings applied during installation or configuration.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-01 full match
blocks

Hardened baselines and configuration management explicitly require correct default file permissions.

PR.AA-05 mostly match
blocks

Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.

ID.AM-08 partial match
blocks

Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.

PR.PS-06 partial match
blocks

Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.9 Configuration management mostly match
blocks

Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
