CCPenX-Az Certified Cloud Pentesting eXpert - Azure Questions and Answers

Detailed Solution:

On an Azure VM with a system-assigned managed identity, run:

az login --identity

Then verify:

az account show

For a user-assigned managed identity, specify the client ID:

az login --identity --client-id < client-id >

Microsoft’s Azure CLI documentation confirms az login --identity for system-assigned managed identities and --client-id, --object-id, or --resource-id for user-assigned identities.

Correct answer:

B. az login --identity

================

Detailed Solution:

In an Entra ID abuse path, a privileged user such as User Administrator may reset another user’s password. In logs, this appears as a user update operation involving the password profile.

Check audit logs in the portal:

Microsoft Entra ID → Monitoring → Audit logs

Or query via Microsoft Graph/Azure tooling depending on permissions.

The activity to look for is generally:

Update user

Modified property: passwordProfile

The other options represent different activities:

Microsoft.Authorization/roleAssignments/write = RBAC role assignment change

Microsoft.Storage/storageAccounts/listKeys/action = storage account key retrieval

Microsoft.KeyVault/vaults/secrets/read = Key Vault secret read

Correct answer:

B. Update user / password profile modification

Detailed Solution:

Start by listing all Azure resources accessible to the compromised user.

az resource list --output table

The environment exposes at least these resources:

RnD-Tools Excalibur-Resources ukwest Microsoft.Web/sites

WebAppTokenIdentity Excalibur-Resources ukwest Microsoft.ManagedIdentity/userAssignedIdentities

The most interesting target is the App Service:

RnD-Tools

Web Apps often store configuration values in App Settings. These commonly contain secrets, flags, API keys, connection strings, or credentials.

Query the App Service application settings:

az webapp config appsettings list \

--name RnD-Tools \

--resource-group Excalibur-Resources \

--output json

Look for keys such as:

Flag

secret

password

token

connectionString

clientSecret

The exposed app setting contains:

{

" name " : " Flag " ,

" slotSetting " : false,

" value " : " Flag{a92f7e0c3c4b9d88a1f54e6723d4c1a2} "

}

Final Answer:

Flag{a92f7e0c3c4b9d88a1f54e6723d4c1a2}

================

Detailed Solution:

From Q7, you should recover a limited-access SAS token or storage access information.

Set the storage account name and SAS token:

ACCOUNT= " excaliburstore "

SAS= " < recovered-sas-token > "

List containers:

az storage container list \

--account-name " $ACCOUNT " \

--sas-token " $SAS " \

--output table

The available container is:

sensitive-files

You can also confirm directly:

az storage blob list \

--account-name " $ACCOUNT " \

--container-name sensitive-files \

--sas-token " $SAS " \

--output table

Final Answer:

C. sensitive-files

Tenant ID: 8f34c1de-1198-4c2a-b1a8-1eaa72f6e99a

Subscription ID: 5d8e44ac-24a9-43d9-9cb5-71b227a58021

Detailed Solution:

Log in with the supplied account:

az login -u james.ward@cloudcorpsec.onmicrosoft.com -p ' < password > '

Show the active Azure context:

az account show --output json

Expected relevant output:

{

" id " : " 5d8e44ac-24a9-43d9-9cb5-71b227a58021 " ,

" name " : " CloudCorp Security Lab " ,

" tenantDefaultDomain " : " cloudcorpsec.onmicrosoft.com " ,

" tenantId " : " 8f34c1de-1198-4c2a-b1a8-1eaa72f6e99a "

}

The tenantId is the Microsoft Entra tenant ID. The id field is the subscription ID.

Flag{managed_identity_can_read_keyvault_secrets}

Detailed Solution:

List Key Vaults:

az keyvault list --output table

List secrets:

az keyvault secret list \

--vault-name kv-finance-prod \

--output table

Expected output:

Name Enabled

---------------- --------

db-password True

api-token True

internal-flag True

Retrieve the flag secret:

az keyvault secret show \

--vault-name kv-finance-prod \

--name internal-flag \

--query value \

--output tsv

Expected value:

Flag{managed_identity_can_read_keyvault_secrets}

Azure Key Vault can use Azure RBAC for secrets, keys, and certificates, including data-plane secret access.
