Low risk7th percentile - higher than 7% of all known CVEs
Summary
AVideo to otwartoźródłowa platforma wideo, która w wersjach 29.0 i wcześniejszych ma lukę w zabezpieczeniach w pliku `objects/configurationUpdate.json.php`. Luka ta pozwala na modyfikację globalnych ustawień witryny przez atakującego, gdy administrator odwiedzi złośliwą stronę, co prowadzi do nieautoryzowanych zmian w konfiguracji witryny.
Risk Assessment
Organizacja narażona jest na poważne ryzyko, ponieważ atakujący może zmienić kluczowe ustawienia witryny, takie jak URL kodera, dane SMTP oraz inne istotne informacje, co może prowadzić do utraty kontroli nad systemem. Tego typu atak może również wpłynąć na reputację organizacji oraz zaufanie użytkowników.
Recommendation
Zaleca się aktualizację AVideo do wersji zawierającej poprawkę z commit f9492f5e6123dff0292d5bb3164fde7665dc36b4 oraz wdrożenie dodatkowych mechanizmów weryfikacji, takich jak `forbidIfIsUntrustedRequest()` i walidacja nagłówków Origin/Referer.

- CVE-2026-113364Critical
Buffer overflow in the data receiving process in NEC WebSAM WinShare versions 7.5.0 and earlier, 7.6.0, and 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary code with SYSTEM privileges via a crafted packet with a malformed data size value in the protocol header.
- CVE-2026-113363Critical
Improper input validation in the network communication processing in NEC WebSAM WinShare versions 7.2.0 through 7.5.0, 7.6.0, and 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary commands with SYSTEM privileges via a crafted network packet sent to the computer running WinShare.
- CVE-2026-124560Critical
A vulnerability was found in D-Link DIR-878 version 1.20B05 in the GetCAPTCHAsetting function of bin/prog.cgi (HNAP Handler component). Manipulating the uid argument results in a heap-based buffer overflow. The attack can be initiated remotely and the exploit has been made public.
- CVE-2026-119506Critical

Original NVD description (English source)
WWBN AVideo is an open source video platform. In versions 29.0 and prior, `objects/configurationUpdate.json.php` (also routed via `/updateConfig`) persists dozens of global site settings from `$_POST` but protects the endpoint only with `User::isAdmin()`. It does not call `forbidIfIsUntrustedRequest()`, does not verify a `globalToken`, and does not validate the Origin/Referer header. Because AVideo intentionally sets `session.cookie_samesite=None` to support cross-origin iframe embedding, a logged-in administrator who visits an attacker-controlled page will have the browser auto-submit a cross-origin POST that rewrites the site's encoder URL, SMTP credentials, site `<head>` HTML, logo, favicon, contact email, and more in a single request. Commit f9492f5e6123dff0292d5bb3164fde7665dc36b4 contains a fix.
