CVE-2020-0790
HighSummary
W systemie występuje lokalna podatność na podniesienie uprawnień, związana z obsługą określonych wywołań przez splwow64.exe. Atakujący, który skutecznie wykorzysta tę podatność, może podnieść swoje uprawnienia z niskich do średnich na zaatakowanym systemie.
Risk Assessment
Choć ta podatność sama w sobie nie umożliwia wykonania dowolnego kodu, może być wykorzystana w połączeniu z inną podatnością, co stwarza ryzyko uruchomienia złośliwego kodu z wyższymi uprawnieniami.
Recommendation
Zaleca się zastosowanie aktualizacji zabezpieczeń, która zapewnia prawidłowe obsługiwanie wywołań przez splwow64.exe, aby zminimalizować ryzyko związane z tą podatnością.

Original NVD description (English source)
<p>A local elevation of privilege vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited the vulnerability could elevate privileges on an affected system from low-integrity to medium-integrity.</p> <p>This vulnerability by itself does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted.</p> <p>The security update addresses the vulnerability by ensuring splwow64.exe properly handles these calls..</p>
