The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

## Summary:
An unauthenticated attacker can reach a Deserialization of Untrusted Data vulnerability that can allow them to execute arbitrary code as SYSTEM/root.
## Vulnerability Analysis:
In the web.xml file, we can see one of the default available servlets is the `CewolfServlet` servlet.
```
<servlet>
<servlet-name>CewolfServlet</servlet-name>
<servlet-class>de.laures.cewolf.CewolfRenderer</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>overliburl</param-name>
<param-value>/js/overlib.js</param-value>
</init-param>
<init-param>
<param-name>storage</param-name>
<param-value>de.laures.cewolf.storage.FileStorage</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
...
<servlet-mapping>
<servlet-name>CewolfServlet</servlet-name>
<url-pattern>/cewolf/*</url-pattern>
</servlet-mapping>
```
This servlet, contains the following code:
```
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
if (debugged) {
logRequest(request);
}
addHeaders(response);
if ((request.getParameter("state") != null) || (!request.getParameterNames().hasMoreElements())) {
requestState(response);
return;
}
int width = 400;
int height = 400;
boolean removeAfterRendering = false;
if (request.getParameter("removeAfterRendering") != null) {
removeAfterRendering = true;
}
if (request.getParameter("width") != null) {
width = Integer.parseInt(request.getParameter("width"));
}
if (request.getParameter("height") != null) {
height = Integer.parseInt(request.getParameter("height"));
}
if (!renderingEnabled) {
renderNotEnabled(response, 400, 50);
return;
}
if ((width > config.getMaxImageWidth()) || (height > config.getMaxImageHeight())) {
renderImageTooLarge(response, 400, 50);
return;
}
String imgKey = request.getParameter("img"); // 1
if (imgKey == null) {
logAndRenderException(new ServletException("no 'img' parameter provided for Cewolf servlet."), response,
width, height);
return;
}
Storage storage = config.getStorage();
ChartImage chartImage = storage.getChartImage(imgKey, request); // 2
```
At [1] the code sets the `imgKey` variable using the GET parameter `img`. Later at [2], the code then calls the `storage.getChartImage` method with the attacker supplied `img`. You maybe wondering what class the `storage` instance is. This was mapped as an initializing parameter to the servlet code in the web.xml file:
```
<init-param>
<param-name>storage</param-name>
<param-value>de.laures.cewolf.storage.FileStorage</param-value>
</init-param>
```
```
public class FileStorage implements Storage {
static final long serialVersionUID = -6342203760851077577L;
String basePath = null;
List stored = new ArrayList();
private boolean deleteOnExit = false;
//...
public void init(ServletContext servletContext) throws CewolfException {
basePath = servletContext.getRealPath("/");
Configuration config = Configuration.getInstance(servletContext);
deleteOnExit = "true".equalsIgnoreCase("" + (String) config.getParameters().get("FileStorage.deleteOnExit"));
servletContext.log("FileStorage initialized, deleteOnExit=" + deleteOnExit);
}
//...
private String getFileName(String id) {
return basePath + "_chart" + id; // 4
}
//...
public ChartImage getChartImage(String id, HttpServletRequest request) {
ChartImage res = null;
ObjectInputStream ois = null;
try {
ois = new ObjectInputStream(new FileInputStream(getFileName(id))); // 3
res = (ChartImage) ois.readObject(); // 5
ois.close();
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (ois != null) {
try {
ois.close();
} catch (IOException ioex) {
ioex.printStackTrace();
}
}
}
return res;
}
```
At [3] the code calls `getFileName` using the attacker controlled `id` GET parameter which returns a path to a file on the filesystem using `basePath`. This field is set in the `init` method of the servlet. On the same line, the code creates a new `ObjectInputStream` instance from the supplied filepath via `FileInputStream`. This path is attacker controlled at [4], however, there is no need to (ab)use traversals here for exploitation.
The most important point is that at [5] the code calls `readObject` using the contents of the file without any further lookahead validation.
## Exploitation:
For exploitation, an attacker can (ab)use the `MDMLogUploaderServlet` servlet to plant a file on the filsystem with controlled content inside. Here is the corresponding web.xml entry:
```
<servlet>
<servlet-name>MDMLogUploaderServlet</servlet-name>
<servlet-class>com.me.mdm.onpremise.webclient.log.MDMLogUploaderServlet</servlet-class>
</servlet>
...
<servlet-mapping>
<servlet-name>MDMLogUploaderServlet</servlet-name>
<url-pattern>/mdm/mdmLogUploader</url-pattern>
<url-pattern>/mdm/client/v1/mdmLogUploader</url-pattern>
</servlet-mapping>
```
```

}
```
We can see that at [1] the `udid` variable is controlled using the `udid` GET parameter from a POST request. At [2] the `fileName` variable is controlled from the GET parameter `filename`. This `filename` GET parameter is actually filtered in 2 different ways for malicious values. At [3] a path is contructed using the GET parameter from [1] and at [4] a `mkdirs` primitive is hit. This is important because the _charts directory doesn't exist on the filesystem which is needed in order to exploit the deserialization bug. There is some validation on the `filename` at [5] which calls `FileUploadUtil.hasVulnerabilityInFileName` to check for directory traversals and an allow list of extensions.
Of course, this doesn't stop `udid` from containing directory traversals, but I digress. At [6] the `absoluteFileName` variable is built up from the attacker influenced path at [3] using the filename from [2] and at [7] the binary input stream is read from the attacker controlled POST body. Finally at [8] and [9] the file is opened and the contents of the request is written to disk. What is not apparent however, is that further validation is performed on the `filename` at [2]. Let's take one more look at the web.xml file:
```
<init-param>
<param-name>config-file</param-name>
<param-value>security-regex.xml,security-mdm-regex.xml,security-mdm-api-regex.xml,security-properties.xml,security-common.xml,security-admin-sec-settings.xml,security-fws.xml,security-api.xml,security-patch-restapi.xml,security-mdm-groupdevices.xml,security-mdm-admin.xml,security-mdm-general.xml,security-mdm-agent.xml,security-mdm-reports.xml,security-mdm-inventory.xml,security-mdm-appmgmt.xml,security-mdm-docmgmt.xml,security-mdm-configuration.xml,security-defaultresponseheaders.xml,security-mdm-remote.xml,security-mdm-api-json.xml,security-mdm-api-get.xml,security-mdm-api-post.xml,security-mdm-api-put.xml,security-mdm-api-delete.xml,security-mdm-privacy.xml,security-mdm-osmgmt.xml,security-mdmapi-appmgmt.xml,security-mdmapi-profilejson.xml,security-mdmapi-profilemgmt.xml,security-mdm-compliance.xml,security-mdm-geofence.xml,security-mdmapi-sdp.xml,security-mdmp-CEA.xml,security-mdmapi-supporttab.xml,security-mdmapi-general.xml,security-mdm-roles.xml,security-mdm-technicians.xml,security-mdm-cea.xml,security-mdmapi-content-mgmt.xml,security-config.xml,security-patch.xml,security-patch-apd-scan.xml,security-patch-apd-scan-views.xml,security-patch-deployment.xml,security-patch-views.xml,security-patch-config.xml,security-patch-onpremise.xml,security-patch-server.xml,security-onpremise-common.xml,security-mdm-onpremise-files.xml,security-mdmapi-directory.xml,security-admin.xml,security-onpremise-admin.xml,security-reports.xml,security-inventory.xml,security-custom-fields.xml</param-value>
</init-param>
```
The file that stands out is the `security-mdm-agent.xml` config file. The corrosponding entry for the `MDMLogUploaderServlet` servlet looks like this:
```
<url path="/mdm/mdmLogUploader" apiscope="MDMCloudEnrollment" authentication="required" duration="60" threshold="10" lock-period="60" method="post" csrf="false">
<param name="platform" regex="ios|android"/>
<param name="filename" regex="logger.txt|logger.zip|mdmlogs.zip|managedprofile_mdmlogs.zip"/>
<param name="uuid" regex="safestring"/>
<param name="udid" regex="udid"/>
<param name="erid" type="long"/>
<param name="authtoken" regex="apikey" secret="true"/>
<param name="SCOPE" regex="scope" />
<param name="encapiKey" regex="encapiKey" max-len="200" />
<param name="initiatedBy" regex="safestring"/>
<param name="extraData" type="JSONObject" template="supportIssueDetailsJson" max-len="2500"/>
</url>
```
Note that the authentication attribute is ignored in this case. The `filename` GET parameter is restricted to the following strings: "logger.txt", "logger.zip", "mdmlogs.zip" and "managedprofile_mdmlogs.zip" using a regex pattern. For exploitation, this limitation doesn't matter since the deserialization bug permits a completely controlled filename.
