Glassfish Server – Unquoted Service Path Privilege Escalation
# Title: Glassfish Server - Unquoted Service Path Privilege Escalation # Date: 28/09/2016 # Author: s0nk3y # Software link: https://glassfish.java.net/download.html # Tested: Windows Server 2008 r2 (Metasploitable3) 1. Description Glassfish Server a service 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. 2. Proof C:\vagrant>sc qc domain1 [SC] QueryServiceConfig SUCCESS SERVICE_NAME: domain1 TYPE : 10 WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:\glassfish\glassfish4\glassfish\domains\domain1\bin\domain1Service.exe LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : domain1 GlassFish Server DEPENDENCIES : tcpip SERVICE_START_NAME : LocalSystem 3. Exploit: A successful attempt would require the local user to be able to insert their code in the system 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. |
