CVE-2020-15261

38
FAUCET Score

CVE-2020-15261 describes an unquoted service path vulnerability in the Veyon Service on Windows, affecting versions prior to 4.4.2. This flaw allows local authenticated users with administrative privileges to execute arbitrary code with LocalSystem privileges. While rated Medium severity (CVSS 6.7), its high impact on confidentiality, integrity, and availability is contingent on an attacker already possessing administrative access. Although not observed in active exploitation, public exploit code exists (EDB-49925), yet it has garnered minimal community discussion or media coverage.
