CERTFR-2026-AVI-0544
Vulnerability from certfr_avis

De multiples vulnérabilités ont été découvertes dans les produits Cisco. Certaines d'entre elles permettent à un attaquant de provoquer une exécution de code arbitraire à distance, un déni de service à distance et une falsification de requêtes côté serveur (SSRF).

Solutions

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

L'éditeur indique que les appareils SG350 et SG350X ne sont plus supportés et ne recevront pas de correctif, mais propose une mesure de contournement pour la vulnérabilité CVE-2026-20185.
