Description Preview
A vulnerability was discovered in Centreon-Web component of Centreon Platform 20.10.0 where the anti-CSRF token generation mechanism is predictable. This predictability undermines the security purpose of these tokens, potentially allowing attackers to conduct Cross-Site Request Forgery (CSRF) attacks. The most critical impact is that attackers could exploit this vulnerability to add unauthorized administrator users to the system, effectively gaining administrative control over the Centreon Platform.
Overview
This vulnerability (CVE-2021-28055) is classified as CWE-330 (Use of Insufficiently Random Values), affecting the Centreon Platform 20.10.0. The security issue lies in the predictable generation of anti-CSRF tokens, which are meant to protect against Cross-Site Request Forgery attacks. When these tokens can be predicted, attackers can craft malicious requests that bypass this protection mechanism. In this specific case, an attacker could potentially execute actions on behalf of authenticated users, including the critical operation of adding new administrator accounts to the system. This vulnerability poses a significant security risk as it could lead to complete compromise of the Centreon monitoring system.
Remediation
Organizations using Centreon Platform 20.10.0 should take the following actions:
- Update to the latest version of Centreon Platform that contains the fix for this vulnerability.
- Review the GitHub pull request #9612 which addresses this issue to understand the changes made.
- Audit user accounts, especially administrator accounts, for any unauthorized additions.
- Implement additional security controls such as IP restrictions for administrative access if possible.
- Monitor logs for suspicious activities, particularly around user creation events.
- Consider implementing additional authentication factors for administrative actions.
