CVE-2026-33191
HighSummary
Free5GC to projekt open-source dla sieci rdzeniowych 5G, który w wersjach przed 1.4.2 jest podatny na wstrzykiwanie bajtów null w parametrach ścieżki URL. Zdalny atakujący może wstrzyknąć bajty null do parametru supi API Nudm_SubscriberDataManagement, co prowadzi do błędu 500 Internal Server Error.
Risk Assessment
Podatność ta może być wykorzystana do ataków typu denial of service, co może prowadzić do niedostępności usług dla użytkowników. W wyniku wstrzykiwania bajtów null, system nieprawidłowo przetwarza żądania, co może wpływać na stabilność całej aplikacji.
Recommendation
Zaleca się aktualizację do wersji 1.4.2 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto wdrożyć mechanizmy walidacji wejścia, aby zapobiec podobnym atakom w przyszłości.

Original NVD description (English source)
Free5GC is an open-source Linux Foundation project for 5th generation (5G) mobile core networks. Versions prior to 1.4.2 are vulnerable to null byte injection in URL path parameters. A remote attacker can inject null bytes (URL-encoded as %00) into the supi path parameter of the UDM's Nudm_SubscriberDataManagement API. This causes URL parsing failure in Go's net/url package with the error "invalid control character in URL", resulting in a 500 Internal Server Error. This null byte injection vulnerability can be exploited for denial of service attacks. When the supi parameter contains null characters, the UDM attempts to construct a URL for UDR that includes these control characters. Go's URL parser rejects them, causing the request to fail with 500 instead of properly validating input and returning 400 Bad Request. This issue has been fixed in version 1.4.2.
