CVE-2011-4197
HighSummary
W implementacji PKI w pfSense przed wersją 2.0.1, plik etc/inc/certs.inc tworzy każdy certyfikat X.509 z prawdziwą wartością dla podstawowego ograniczenia CA. To umożliwia zdalnym atakującym tworzenie sub-certyfikatów dla dowolnych podmiotów, wykorzystując klucz prywatny.
Risk Assessment
Organizacja może być narażona na nieautoryzowane użycie certyfikatów, co prowadzi do potencjalnych ataków typu spoofing oraz naruszenia integralności komunikacji.
Recommendation
Zaleca się aktualizację pfSense do wersji 2.0.1 lub nowszej, aby usunąć tę podatność oraz przegląd istniejących certyfikatów w celu oceny ich bezpieczeństwa.

SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
Original NVD description (English source)
etc/inc/certs.inc in the PKI implementation in pfSense before 2.0.1 creates each X.509 certificate with a true value for the CA basic constraint, which allows remote attackers to create sub-certificates for arbitrary subjects by leveraging the private key.
