17
FAUCET Score

CVE-2020-12431 is a local privilege escalation vulnerability affecting Splashtop Software Updater (before 1.5.6.16), Splashtop Streamer (before 3.3.8.0), and Splashtop Business (before 3.3.8.0). It stems from insecure permissions on configuration files and named pipes, allowing an attacker to force permission changes on Splashtop files and directories, leading to DLL hijacking and elevation to NT AUTHORITY/SYSTEM. With a CVSS score of 6.6 (Medium), this vulnerability requires local access and user interaction (UI:R) but has high impact on integrity and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
