Vulnerability from certfr_avis - Published: - Updated:
De multiples vulnérabilités ont été découvertes dans les routeurs Cisco Small Business. Elles permettent à un attaquant de provoquer une atteinte à la confidentialité des données, un contournement de la politique de sécurité et une exécution de code arbitraire à distance.
Solution
Les routeurs Cisco Small Buisness ci-dessus ne sont plus maintenus par l'éditeur. Ils ne recevront donc pas de correctif pour cette vulnérabilité critique.
Le CERT-FR recommande fortement de les remplacer par des équipements maintenus par l'éditeur.
Contournement provisoire
Le CERT-FR recommande fortement de désactiver l'interface d'administration. Se référer à la procédure documentée dans l'avis de l'éditeur (cf. Section documentation).

Summary
A vulnerability in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, and RV082 Routers could allow an unauthenticated, remote attacker to bypass authentication on an affected device.
This vulnerability is due to improper validation of user input within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to bypass authentication and gain root access on the underlying operating system.

Summary
A vulnerability in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320 and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary commands on an affected device.
This vulnerability is due to improper validation of user input within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to gain root-level privileges and access unauthorized data. To exploit this vulnerability, an attacker would need to have valid administrative credentials on the affected device.

Summary
A vulnerability in the web-based management interface of Cisco Small Business Routers RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary commands on an affected device.
This vulnerability is due to improper validation of user input within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to gain root-level privileges and access unauthorized data. To exploit this vulnerability, an attacker would need to have valid administrative credentials on the affected device.
Cisco has not and will not release software updates that address this vulnerability. However, administrators may disable the affected feature as described in the Workarounds ["#workarounds"] section.
