Chain of evidence and sources3 verified claims

Netgate pfSense CE 2.7.0 ile 2.9.0 arasında, IPsec Mobile yetkisine sahip kimliği doğrulanmış kullanıcıların tek satırlık '}' karakterli banner ekleyerek unquoted strongswan.conf özniteliğini kaçırıp charon.start‑scripts girdileri eklemesine ve bu komutların root yetkileriyle çalıştırılmasına izin veren bir konfigürasyon enjeksiyon açığı vardır.

Başarılı istismar, root yetkileriyle rastgele komut çalıştırılmasına yol açar ve sistemin tam ele geçirilmesini sağlar.
