Vulnerability Title
Local Privilege Escalation via Insecure DLL Permissions in Remote Utilities Host <=7.7.3.0
Source: CVE Program / CVE List V5
Vulnerability Description
Remote Utilities Host <=7.7.3.0 sets insecure ACLs on all DLL files in the installation directory (C:\Program Files (x86)\Remote Utilities - Host\), granting FULL CONTROL (F) to the built-in Everyone group (BUILTIN\Everyone, S-1-1-0). A Windows service running as NT AUTHORITY\SYSTEM loads DLLs from this directory. The DLLs are file-locked at runtime, but a race window exists when the service is stopped (e.g. during a software update or following a crash), during which a local unprivileged attacker can replace a DLL with a malicious payload. Upon service restart, the payload executes as NT AUTHORITY\SYSTEM. The DLL confirmed as actively loaded during testing is libasset32.dll. Additional DLLs in the same directory (eventmsg.dll, libcodec32.dll, vp8encoder.dll, vp8decoder.dll, webmvorbisdecoder.dll, webmvorbisencoder.dll, webmmux.dll) share identical insecure permissions.
