In IOBit Advanced System Care (AscService.exe) 15, an attacker with SEImpersonatePrivilege can create a named pipe with the same name as one of ASCService's named pipes. ASCService first tries to connect before trying to create the named pipes, because of that during login the service will try to connect to the attacker which will lead to either escalation of privileges (through token manipulation and ImpersonateNamedPipeClient() ) from ADMIN -> SYSTEM or from Local ADMIN-> Domain ADMIN depending on the user and named pipe that is used.
Security readout for executives and security teams
Plain-English summary
This issue affects IObit Advanced SystemCare 15 service behavior on Windows. A local attacker with specific impersonation privilege can abuse named-pipe handling during login to gain higher privileges, potentially SYSTEM or domain administrator depending on the logged-in user context.
Executive priority
Prioritize review on administrator workstations and servers where this utility is installed. The business risk is privilege escalation after local compromise, not unauthenticated remote entry.
Technical view
ASCService.exe reportedly connects to a named pipe before creating its own. An attacker with SEImpersonatePrivilege can pre-create a matching pipe and use named-pipe client impersonation to manipulate tokens and escalate privileges.
Likely exposure
Exposure is limited to Windows systems running IObit Advanced SystemCare 15 with ASCService.exe present, where a local attacker already has SEImpersonatePrivilege or similar local administrative foothold.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. A public GitHub reference is listed, but no in-the-wild exploitation claim is provided.
Researcher notes
Root cause is service named-pipe ordering: connect first, create later. Missing evidence includes CVSS, CWE mapping, precise fixed version, vendor advisory, and verified exploitation status.
Mitigation direction
Inventory endpoints for IObit Advanced SystemCare or AscService.exe version 15.
Check IObit/vendor guidance for fixed versions or supported remediation.
Remove the software where it is not business-required.
Restrict local administrator rights and accounts with SEImpersonatePrivilege.
Monitor for suspicious named-pipe impersonation and unexpected privilege changes.
Validation and detection
Confirm whether AscService.exe from Advanced SystemCare 15 is installed and running.
Review local administrator membership and users with impersonation privileges.
Compare installed versions against vendor guidance or available fixed releases.
Check endpoint telemetry for unusual token impersonation or service-to-pipe behavior.
