CVE-2026-20245
Publiée le 2026-06-04 · Dernière modification le 2026-07-23 KEV — activement exploitée
Les contrôleurs, gestionnaires et validateurs Cisco Catalyst SD-WAN sont affectés par une faille dans leur interface en ligne de commande. Un attaquant disposant déjà de privilèges locaux « netadmin » peut obtenir un accès root complet au système en téléchargeant un fichier spécifiquement conçu à cet effet. Comme cela nécessite des identifiants d'administration valides et un accès local, cette faille ne peut pas être déclenchée à distance par un utilisateur non authentifié.
ACTIVEMENT EXPLOITÉE (KEV DE LA CISA)

RÉFÉRENCES
Description officielle du NVD (en anglais)
A vulnerability in the CLI of Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an authenticated, local attacker to execute arbitrary commands as root by supplying a crafted file to the affected system. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by uploading a crafted file to the affected system. A successful exploit could allow the attacker to perform command injection attacks on an affected system and elevate their privileges as the root user. To exploit this vulnerability, the attacker must have netadmin privileges on the affected system. This would require valid credentials or exploitation of or . Cisco is not aware of successful exploitation by other methods. Cisco has observed limited cases where the exploitation of this bug resulted in a configuration change pushed to edge devices. Cisco recommends that customers upgrade to the fixed software that is documented in the that was published on May 14, 2026, and verify the configuration of the edge devices.
