Ce mail provient de l'extérieur, restons vigilants ===================================================================== CERT-Renater Note d'Information No. 2026/VULN197 _____________________________________________________________________ DATE : 19/02/2026 HARDWARE PLATFORM(S): / OPERATING SYSTEM(S): Systems running Tenable Security Center versions prior to 6.8.0. ===================================================================== https://www.tenable.com/security/tns-2026-07 _____________________________________________________________________ [R1] Security Center Version 6.8.0 Fixes Multiple Vulnerabilities Critical Synopsis Security Center leverages third-party software to help provide underlying functionality. Several of the third-party components (php jwt, libssh, postgresql) were found to contain vulnerabilities, and updated versions have been made available by the providers. Out of caution and in line with best practice, Tenable has opted to upgrade these components to address the potential impact of the issues. Security Center 6.8.0 updates php jwt to version 7.0.2, libssh to version 1.11.1 and postgresql to version 16.11 to address the identified vulnerabilities. Additionally, several externally reported vulnerabilities were fixed: An Indirect Object Reference (IDOR) in Security Center allows an authenticated remote attacker to escalate privileges via the 'owner' parameter. (CVE-2026-2697) An improper access control vulnerability exists where an authenticated user could access areas outside of their authorized scope. (CVE-2026-2698) Solution Tenable has released Security Center 6.8.0 to address these issues. The installation files can be obtained from the Tenable Downloads Portal: https://www.tenable.com/downloads/security-center Note: Patches that include fixes for Apache, PHP and Libcurl were recently released (https://www.tenable.com/security/tns-2026-06). Tenable Security Center 6.8.0 includes all of these fixes. Please refer to the Tenable SC Release Notes for more information.
