The O2 Connection Manager’s service suffers from an unquoted search path issue impacting the Import WiFi ‘TGCM_ImportWiFiSvc’ service for Windows. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could potentially be executed during application startup or reboot. If successful, the local user’s code would execute with the elevated privileges of the application.
