CVE-2019-11687
HighCVSS 7.8Summary
W formacie pliku DICOM Part 10 zidentyfikowano problem, który pozwala na umieszczanie dowolnych nagłówków wykonywalnych w 128-bajtowym preambule pliku. Ta luka umożliwia kompromitację systemu, ponieważ złośliwe pliki DICOM są często wymieniane między urządzeniami medycznymi a systemami szpitalnymi.
Risk Assessment
Zagrożenie dla organizacji polega na możliwości naruszenia przepisów dotyczących ochrony danych osobowych, takich jak HIPAA, oraz na ryzyku systemowego kompromitowania, co może prowadzić do poważnych konsekwencji prawnych i finansowych.
Recommendation
Zaleca się wdrożenie ścisłych polityk bezpieczeństwa dotyczących plików DICOM oraz skonfigurowanie oprogramowania antywirusowego w taki sposób, aby skanowało również pliki medyczne, aby zminimalizować ryzyko wykorzystania tej podatności.

Original NVD description (English source)
An issue was discovered in the DICOM Part 10 File Format in the NEMA DICOM Standard 1995 through 2019b and continuing in current implementations. The 128-byte preamble of a DICOM file that complies with this specification can contain arbitrary executable headers for multiple operating systems, including Portable Executable (PE) files for Windows and Executable and Linkable Format (ELF) files for Linux-based systems. This space is left unspecified so that dual-purpose files can be created. For example, dual-purpose TIFF/DICOM files are used in digital whole slide imaging applications in medicine. This design flaw enables system-wide compromise as malicious DICOM files are routinely shared between medical devices and hospital systems and transported via removable media for patient care coordination. To exploit this vulnerability, someone must execute the maliciously crafted file. These files can be executable even with the .dcm file extension. Anti-malware configurations at healthcare facilities often ignore medical imagery. DICOM files exist on systems that process protected health information, and successful exploitation could result in violations of regulatory compliance requirements such as HIPAA and FDA postmarket obligations.
