CVE-2026-14208
HighCVSS 7.3Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
Remote Utilities Host <=7.7.3.0 sets insecure ACLs on all DLL files in the installation directory, granting FULL CONTROL to the Everyone group. A Windows service running as SYSTEM loads DLLs from this directory. A race window exists when the service is stopped, during which a local unprivileged attacker can replace a DLL with a malicious payload, which executes as SYSTEM upon service restart.
Risk Assessment
A local attacker can gain full control of the system with SYSTEM privileges, leading to complete machine compromise.
Recommendation
Immediately update Remote Utilities Host to the latest version that fixes the ACL permissions, and restrict local access to the system.

Original NVD description (English source)
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.
