CERTFR-2021-AVI-642

Vulnerability from certfr_avis

Une vulnérabilité a été découverte dans les produits Cisco. Elle permet à un attaquant de provoquer une exécution de code arbitraire à distance et un déni de service à distance.

Note : Cette vulnérabilité affecte le service UPnP (Universal Plug-and-Play). Par défaut, le service est activé uniquement sur les interfaces associées au réseau local et est désactivé sur les interfaces externes.

Solution

Les produits affectés ne sont plus maintenus par l'éditeur et ne disposeront donc pas de correctif.

Le CERT-FR recommande fortement de procéder au remplacement de ces équipements.

Contournement provisoire

Désactiver le service UPnP via l'interface d'administration (menu 'Basic Settings' / 'UPnP', cocher les cases 'Disabled').

CVE-2021-34730 (GCVE-0-2021-34730)

Vulnerability from cvelistv5

Published

Severity ?

9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-121

Summary

A vulnerability in the Universal Plug-and-Play (UPnP) service of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of incoming UPnP traffic. An attacker could exploit this vulnerability by sending a crafted UPnP request to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a DoS condition. Cisco has not released software updates that address this vulnerability.
