Jenkins Attack Framework
Description
This project can currently perform the following tasks:
-
AccessCheck: Test credentials and provide a rough overview of their access levels
-
ConsoleOutput: Dump the console output of the last build of every job on the server (Can be Gigabytes of data, but good for finding credentials)
-
CreateAPIToken: Creates an API Token for the current user (Or another user if you have administrative credentials)
-
DeleteAPIToken: Deletes an API Token for the current user (Or another user if you have administrative credentials. Lists existing ones if no token supplied)
-
DeleteJob: Delete a Job, or failing that, attempt a number of follow-up mitigations from most-to-least effective.
-
DumpCreds: Dump credentials (Uses administrative credentials to dump credentials via Jenkins Console)
-
DumpCredsViaJob: Dump credentials via job creation and explicit enumeration (User needs at least Add Job permissions)
-
ListAPITokens: List existing API tokens for the current user (Or another user if you have administrative credentials)
-
ListJobs: List existing Jenkins Jobs (Good For finding specific jobs)
-
RunCommand: Run system command and get output/errors back (Uses administrative credentials and Jenkins Console)
-
RunJob: Upload a script and run it as a job. Also run "Ghost Jobs" that don't terminate or show up in Jenkins (after launch)
-
RunScript: Run Groovy scripts (Uses administrative credentials to run a Groovy Script via Jenkins Console)
-
UploadFile: Upload a file (Uses administrative credentials and chunked uploading via Jenkins Console)
-
WhoAmI: Get the credentialed user's Jenkins groups (Usually contains their domain groups)
-
More things are in the works...
Installing
Run the following commands:
git clone [email protected]:Accenture/jenkins-attack-framework.git
cd jaf
chmod +x jaf
sudo ./jaf --install
./jaf --install
Before you can use the RunJob "ghost job" feature against Windows Jenkins Slaves, you will need to compile the following file data/cpp/windows_ghost_job_helper.cpp using Visual Studio's cl tool (see compile arguments in comment at the top of that file), and then drop the compiled file in data/exe/windows_ghost_job_helper.exe.
Command Line Help
The commandline help should be pretty straight forward, but is provided here with additional notes:
usage: jaf.py <Command> [-h]
Jenkins Attack Framework
positional arguments:
<Command> Subcommand to run (pass sub command for more detailed help):
AccessCheck ConsoleOutput CreateAPIToken DeleteAPIToken
DeleteJob DumpCreds DumpCredsViaJob ListAPITokens ListJobs
RunCommand RunJob RunScript UploadFile WhoAmI
optional arguments:
-h, --help show this help message and exit
Common Usage Notes
For every subcommand, you can get more detailed help by calling JAF with the subcommand and no additional options (or the -h option).
Server URL
For every command (other than requesting help), the -s command is required. This should be the full, base URL to the Jenkins instance.
User Agent
JAF will use the following user agent with each request: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.149 Safari/537.36. This was chosen, at least at the time of this release to fit in. If you wish to use a different user-agent, one can be specified with the -u option.
Output Redirection
For every command, you may pass the -o option with a file path. If passed, JAF will write all output (with the exception of some fatal or critical errors) to the file instead of stdout. This option is particularly useful on Windows where console redirection tends to break on random bytes unless you change the code page.
Credentials
If no credentials are provided, JAF will attempt to connect with anonymous credentials.
Credentials can be provided via two methods. To provide a single set of credentials use the -a option.
Credentials can take three forms: user:password, user:apitoken, or a Cookie string.
In the case of the latter option, the cookie should include the entire cookie (everthing after "Cookie: " in the browser header).
Cookie authentication is particularly useful when the Jenkin server uses federation with another Jenkins server for authentication.
In this scenario, normal user:password auth will not work. API tokens may still work. If not, authenticate in your browser, then pass the cookie.
Cookie authentication can also include a Jenkins Crumb, which should be concatenated to the end of the cookie string to look something like: JSESSIONID.9922756a=node0rhre4wjrdcjz9m4tbqx0qwqn1567.node0|Jenkins-Crumb=f5cb5472851aad76fc45568ef1e4160928d075376fd78c436a58d39b99aae09a
Though JAF can usually determine your authentication type by parsing the string, you can also hint the correct type by prepending your credential string with one of the following (self-explanatory) tags: {USERPASS}, {APITOKEN}, {COOKIE}
For the following two commands, you may pass a single set of credentials using the -a option or you may pass multiple credentials with the -c option: AccessCheck and WhoAmI.
The -c option takes either the path to a file which contains one of the aforementioned credential forms per line, or -. If - is passed, JAF will take credentials via stdin instead of from a file (formatting remains the same).
Timeouts, Threads, and Waiting
HTTP Request Timeouts default to 30 seconds. If you would like a shorter or longer timeout, one can be configured with the -n option.
For certain multi-request methods (ConsoleOutput, AccessCheck, or WhoAmI), the number of threads (and thus number of simultaneous requests) can be configured. By default 4 threads are used. To specify a different number of threads pass the -t option.
For the RunCommand, RunJob, and RunScript methods, in addition to setting a total request timeout, you may pass the -x option to explicitly not wait for the request to return. This can be valuable when starting a SOCKS Proxy or similar long running task.
AccessCheck
This method provides a number of heuristic checks for access levels which are useful for an attacker. A negative result should be accurate. A positive result means that the user potentially has the access, but you will need to perform additonal validation. There are simply too many ways to restrict access in Jenkins and no API for determining granular access levels, so results are not always prefectly accurate. Currently this method checks for the following access: Basic Read Access (read), Create Job Access (build), Some level of Admin Access (admin), Script Console Access (script), Scriptler Groovy Script Plugin Access (scriptler)
usage: jaf.py AccessCheck [-h] -s <Server> [-u <User-Agent>] [-n <Timeout>]
[-o Output File] [-t <Threads>]
[-a [<User>:[<Password>|<API Token>]|<Cookie>]]

cookie string
CreateAPIToken
Used to create an API Token for the user who's credentials are supplied. If the --user option is passed, this command will instead create an API token for the supplied user (but you must have administrative /script console access to do this).
Token Name is entirely optional and can be anything even a duplicate of an existing token name. Tokens are shown under the user's configure page (/user/<username>/configure), so pick a name that will blend in (or no name). If no Token Name is specified and you are creating the token for the current user, Jenkins will pick the name Token Created on <Date>. If creating a token with no Token Name as an admin for another user (or even yourself while using the --user option, the name will actually be blank, and the Jenkins API actually makes this kind of difficult to notice).
On successful token creation, the new API Token will be printed to the screen. You should capture this, as this token can never be viewed again.
usage: jaf.py CreateAPIToken [-h] -s <Server> [-u <User-Agent>] [-n <Timeout>]
[-o Output File] [-a [<User>:[<Password>|<API Token>]|<Cookie>]]
[-U <User Name>] [<Token Name>]
Jenkins Attack Framework
positional arguments:
CreateAPIToken Create an API Token for your user
<Token Name> Token Name which is shown under the user's
configuration page (so pick something that is not too
suspicious). Can be duplicated (There do not appear to
be any restrictions on token names). If not provided,
only token creation date will be shown on user's page.
optional arguments:
-h, --help show this help message and exit
-s <Server>, --server <Server>

Write Output to File
-a [<User>:[<Password>|<API Token>]|<Cookie>], --authentication [<User>:[<Password>|<API Token>]|<Cookie>]
User + Password or API Token, or full JSESSIONID
cookie string
-U <User Name>, --user <User Name>
If provided, will use Jenkins Script Console to add
token for this user. (Requires Admin "/script"
permissions)
DeleteAPIToken
Used to delete an API Token for the user who's credentials are supplied. If the --user option is passed, this command will instead delete the API token for the supplied user (but you must have administrative /script console access to do this).
Token Name or UUID is required to actually delete a token. If not supplied, this function effectively acts like ListAPITokens and returns a list of existing tokens. If a Token Name is supplied this command will try to delete that token and alert you on success or failure. If the name matches multiple tokens, no token will be deleted, and you will receive an error message. In that case, you should instead list tokens (either by calling DeleteAPIToken with no additional arguments, or via calling ListAPITokens), then try again with a Token UUID. Deleted tokens cannot be restored, so make sure you are certain before attempting.
usage: jaf.py DeleteAPIToken [-h] -s <Server> [-u <User-Agent>] [-n <Timeout>]
[-o Output File] [-a [<User>:[<Password>|<API Token>]|<Cookie>]]
[-U <User Name>] [<Token Name or UUID>]

positional arguments:
DeleteAPIToken Delete an API Token for your user
<Token Name or UUID> If not specified, command will return list of tokens
for subsequent calls.

-U <User Name>, --user <User Name>
If provided, will use Jenkins Script Console to delete
token for this user. (Requires Admin "/script"

-N <Node>, --node <Node>
Node (Slave) to execute against. Executes against
"master" if not specified.
DumpCredsViaJob
Dump credentials by creating a Job and explicitly enumerating echoing out all the credentials that are stored and accessible to the user. These credentials are then Base64 encoded so as to prevent Jenkins from redacting them. The credentials are retrieved and formatted. User must have at least Job creation privileges.
usage: jaf.py DumpCredsViaJob [-h] -s <Server> [-u <User-Agent>]
[-n <Timeout>] [-o Output File]
[-a [<User>:[<Password>|<API Token>]|<Cookie>]] [-N <Node>]
[-T <Node Type>] <Task Name>
Jenkins Attack Framework
positional arguments:
DumpCredsViaJob Dump credentials via explicit enumeration of shared
credentials in a job (Only requires job creation
permissions and some shared credentials)
<Task Name> Task to Create, must be unique (may not be deleted if
user doesn't have job deletion permissions, so pick
something that blends in)

Node Type, either: "posix" or "windows". If specified,
you must also pass -N
ListAPITokens
Method simply lists all existing API Tokens for the user who's creds you supplied. If the --user option is passed, this command will instead list the API tokens for the supplied user (but you must have administrative /script console access to do this).
The actual API Tokens cannot be recovered as only a hash is stored, and only Admin users can even access these hashes. So this method is really only useful for getting a list before trying to use CreateAPIToken or DeleteAPIToken.
usage: jaf.py ListAPITokens [-h] -s <Server> [-u <User-Agent>] [-n <Timeout>]
[-o Output File] [-a [<User>:[<Password>|<API Token>]|<Cookie>]]

-x, --no_wait Do not wait for Output
-N <Node>, --node <Node>
Node (Slave) to execute against. Executes against
"master" if not specified.
RunJob
Allows you to run jobs via Jenkins. The command will upload your script or executable and then execute it. The -e option allows you to specify what program is called to execute your uploaded script, otherwise the script is executed by the default handler. The -A allows you to specify an argument string to pass to your script or executable. For exmple, if both the -e and -A option were passed, your file would be executed in this fashion: <executor> <payload name> <argument string>.
The -g option allows you to run "Ghost Jobs". Ghost jobs are jobs which are launched then terminated and deleted so that they do not continue to show up in Jenkins. Due to some clever hackery with this feature, Jenkins does not terminate these jobs (or mark an executor as in-use), and the jobs can run indefinitely on the executing system. This is an excellent way to upload a SOCKS5 server to a slave and run it on a high port to tunnel traffic with only Create Job permissions.
GHOSTJOB OPSEC WARNING 1: In the case of running a GHOST job on a Windows slave, a helper executable is uploaded. If the slave is running as an administrative user, wmic process call create is used as part of the job termination bypass. You should not use this technique if the Windows Slaves are running EDR.
GHOSTJOB OPSEC WARNING 2: You should ensure that your payloads are designed in such a way as to handle deleting themselves upon completion as in the case of Windows slaves, JAF cannot automatically do this.

UploadFile
This method requires administrative credentials with /script access.
This method works by chunking files into pieces small enough to post to the Jenkins server as base64 encoded chunks that are decoded via groovy commands in the console and appended to a file. For this to work, you should ensure that the upload file path is:
-
a full path (no
~or other expansion will be done, nor folders created). -
write-able by the jenkin's system user.
-
In the path format for the OS in use.
In addition, it is critical that the file does not already exist. Due to the mulitiple chunk nature, this process is additive. An existing file will result in the upload file being appended to the existing file.
usage: jaf.py UploadFile [-h] -s <Server> [-u <User-Agent>] [-n <Timeout>]
[-o Output File] [-a [<User>:[<Password>|<API Token>]|<Cookie>]]

-N <Node>, --node <Node>
Node (Slave) to execute against. Executes against

WhoAmI
This method is basically a useability wrapper around /api/whoAmI. This page shows the current logged-in users all the Jenkins groups they are in.
In the case of a LDAP/Domain-Connected Jenkins, this also includes all domain groups for the user (recursively or not depends on admin settings).
usage: jaf.py WhoAmI [-h] -s <Server> [-u <User-Agent>] [-n <Timeout>]
[-o Output File] [-t <Threads>]
[-a [<User>:[<Password>|<API Token>]|<Cookie>]]
[-c <Credential File>]
