Infra Monitoring: Incorrect Default Permissions

Published Updated By the CyberSecBulletin desk

CVE-2025-8432 is a high-severity incorrect default permissions vulnerability in Infra Monitoring from Centreon, with a CVSS 3.1 base score of 8.4 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. The record lists versions 24.10.6, 24.04.9, 23.10.15 as the first without the flaw, so updating Infra Monitoring to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.43% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Infra Monitoring to 24.10.6 or 24.04.9 or 23.10.15, whichever matches your release line, or a later version.
  2. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Incorrect Default Permissions vulnerability in Centreon Infra Monitoring (MBI modules) allows Embedding Scripts within Scripts by CentreonBI user account on the MBI server This issue affects Infra Monitoring: from 24.10.0 before 24.10.6, from 24.04.0 before 24.04.9, from 23.10.0 before 23.10.15.

The underlying weakness: Incorrect Default Permissions

During installation, installed file permissions are set to allow anyone to modify those files.

How developers prevent this class of flaw

  • The architecture needs to access and modification attributes for files to only those users who actually require those actions.
  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
