Vulnerability from certfr_alerte

Le 4 décembre 2023, Apache a publié un avis de sécurité concernant la vulnérabilité critique CVE-2023-50164 concernant le cadriciel Struts 2. Cette vulnérabilité permet à un attaquant non authentifié de téléverser une porte dérobée sur un serveur vulnérable, et ainsi exécuter du code arbitraire à distance.

Le 12 décembre 2023, un premier code d'exploitation a été publié publiquement et le CERT-FR a connaissance de tentatives d'exploitation.

Il est urgent d'effectuer la mise à jour des applications s'appuyant sur le cadriciel Struts dans les plus brefs délais, car le CERT-FR anticipe des tentatives d'exploitation en masse de la vulnérabilité CVE-2023-50164.

Solution

Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
