1. Description:
|
|
|
|
The Anydesk installs as 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:\>sc qc anydesk
|
|
[SC] QueryServiceConfig SUCCESS
|
|
|
|
SERVICE_NAME: anydesk
|
|
TYPE : 10 WIN32_OWN_PROCESS
|
|
START_TYPE : 2 AUTO_START
|
|
ERROR_CONTROL : 1 NORMAL
|
|
BINARY_PATH_NAME : C:\Program Files\AnyDesk\AnyDesk.exe --service
|
|
LOAD_ORDER_GROUP :
|
|
TAG : 0
|
|
DISPLAY_NAME : AnyDesk Service
|
|
DEPENDENCIES : RpcSs
|
|
SERVICE_START_NAME : LocalSystem
|
|
|
|
|
|
3. Exploit:
|
|
|
|
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. |
