Panda Internet Security v17.0.1 - Unquoted Service Path Privilege Escalation ===================================================== # Panda Internet Security v17.0.1 - Unquoted Service Path Privilege Escalation ===================================================== # Vendor Homepage: http://www.pandasecurity.com # Date: 24 Oct 2016 # Version : 17.0.1 # Software Link: http://www.pandasecurity.com/homeusers/downloads/ # Tested on: Windows 7 Ultimate SP1 (EN) # Author: Heliand Dema # Contact: heliand@cyber.al ===================================================== Panda Internet Security installs a service called 'panda_url_filtering' with an unquoted service path running with SYSTEM privileges. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. C:\Users\helik>sc qc panda_url_filtering [SC] QueryServiceConfig SUCCESS SERVICE_NAME: panda_url_filtering TYPE : 10 WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:\Program Files\Panda Security URL Filtering\Panda_URL_Filteringb.exe LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : panda_url_filtering Service DEPENDENCIES : SERVICE_START_NAME : LocalSystem ====Proof-of-Concept==== To properly exploit this vulnerability, the local attacker must insert an executable file in the path of the service. Upon service restart or system reboot, the malicious code will be run with elevated privileges.
