CVE-2017-7921
CriticalCVSS 9.8KEVSummary
W urządzeniach Hikvision z serii DS-2CD2xx2F-I, DS-2CD2xx0F-I, DS-2CD2xx2FWD, DS-2CD4x2xFWD, DS-2CD4xx5, DS-2DFx oraz DS-2CD63xx występuje problem z niewłaściwą autoryzacją. Wersje od V5.2.0 do V5.4.0 mogą pozwolić na eskalację uprawnień przez złośliwego użytkownika, co prowadzi do dostępu do wrażliwych informacji.
Risk Assessment
Niewłaściwa autoryzacja stwarza ryzyko, że nieautoryzowani użytkownicy mogą uzyskać dostęp do systemu i danych, co może prowadzić do poważnych naruszeń bezpieczeństwa w organizacji.
Recommendation
Zaleca się aktualizację urządzeń do najnowszych wersji oprogramowania, które eliminują tę podatność oraz wdrożenie dodatkowych mechanizmów zabezpieczających, aby ograniczyć ryzyko nieautoryzowanego dostępu.

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.
