CVE-2023-20154
Publiée le 2024-11-15 · Dernière modification le 2026-06-17
Les installations de Cisco Modeling Labs utilisant l'authentification externe sont concernées. Un attaquant distant disposant d'identifiants valides provenant du serveur d'authentification externe peut contourner les contrôles de sécurité pour obtenir un accès administratif complet à l'interface web, lui permettant ainsi de modifier ou de supprimer toutes les simulations et les données utilisateur. Cette exploitation est facile à exécuter via le réseau et ne nécessite aucune interaction particulière de l'utilisateur.
DÉTAIL DU VECTEUR CVSS
RÉFÉRENCES
Description officielle du NVD (en anglais)
A vulnerability in the external authentication mechanism of Cisco Modeling Labs could allow an unauthenticated, remote attacker to access the web interface with administrative privileges. This vulnerability is due to the improper handling of certain messages that are returned by the associated external authentication server. An attacker could exploit this vulnerability by logging in to the web interface of an affected server. Under certain conditions, the authentication mechanism would be bypassed and the attacker would be logged in as an administrator. A successful exploit could allow the attacker to obtain administrative privileges on the web interface of an affected server, including the ability to access and modify every simulation and all user-created data. To exploit this vulnerability, the attacker would need valid user credentials that are stored on the associated external authentication server. Cisco has released software updates that address this vulnerability. There are workarounds that address this vulnerability.
