Example Vulnerabilities Detected

This page provides real-world examples of credentials and vulnerabilities actually detected and intercepted by Soteri's Security for Bitbucket Server. Its algorithms can detect private keys, account numbers, OAuth tokens, and numerous other credentials that use proprietary and deterministic string formats.

This is just a sampling of what can be detected by Soteri's Security for Bitbucket! For a comprehensive list of built-in Vulnerability Detection Capabilities, see Vulnerabilities Detected by Security for Bitbucket .

Amazon Web Services (AWS)

There's no more widely used cloud platform than AWS and if your organization is on it, you can't risk exposing access information and committing it to source code. As you spin up new VMs or add users, there are inevitably multiple instances of access keys passed around, and used within the source code -- even if they're just hard-coded for the convenience of testing.

AWS Key

PY

    aws_access_key_id='AKIAIO5FODNN7EXAMPLE'

JS

	const AWSKEY = "AKIALALEMEL33243OLIBE"

CPP

	// Tested with AWS "AKIALALEMEL33243OLIAE"

CPP

	Here's an AWS secret: AKIALALEMEL33243OLIAE

AWS Secret

JS

	const AWSSECRET = "7CE556A3BC234CC1FF9E8A5C324C0BB70AA21B6D"

Facebook

Facebook has had its own share of incidents, but there's no reason to risk exposing your access credentials with a careless push to Bitbucket. Security for Bitbucket scans both for facebook client IDs and facebook secrets.

Facebook Client ID

JAVA

OAuthClientRequest.tokenProvider(OAuthProviderType.FACEBOOK).setClientId("950513172001321")

Facebook Secret

JS

const fb_secret = "3b2e464637e5159024254dd78aadb17a"

Google

With the widespread use of Google as an authentication service, accidentally committing a google OAuth key can leave crucial information for attackers, even if the commit is quickly reverted. Security for Bitbucket supports scanning all incoming commits for Google OAuth tokens and OAuth client IDs, as well as Google API keys.

Google OAuth

JAVA

static final auth_test = "ya29.AHES67zeEn-RDg9CA5gGKMLKuG4uVB7W4O4WjNr-NBfY6Dtad4vbIZ";

JAVA

static final client_test = "147328480433-ivpqgaaldsjv9br163dockt29e200r62.apps.googleusercontent.com";

Google API token

JS

const API_TOKEN = "AIzaSyCLWjZ0_ETxgPOxH-gQYT9ODeWcBBZU5-Q"

Github

Github has credentials which can be used like passwords to authenticate individual developers, OAuth tokens, users with Github server applications, and refresh tokens to get new credentials. Security for Bitbucket scans for all kinds of Github Authentication Tokens.

Github Personal Access Tokens

PY

Github OAuth Tokens

Generic hard-coded passwords

Passwords are still the most common authentication mechanism around, despite the prevalence of more advanced methods such as SSH keys and API keys. To protect against passwords which are accidentally committed, Security for Bitbucket scans incoming commits for generic patterns which look suspiciously like hardcoded passwords. Here are some examples that would be flagged:

JAVA

passwd = "qwerty"

db_pass = "qwerty"

PASS = 'secret'

password = "secret"

Note that, due to its nature, the generic password rule may generate more false positives than the more specific rules – developers can add an inline annotation to indicate to Security for Bitbucket to ignore the occurrence. See Allow-listing Detected Secrets.

Heroku

Production Heroku API keys can easily end up committed in your repository when a testing script gets accidentally pushed.

Heroku API key

JS

heroku_auth = C7A8B9B3-2C9C-BECC-4C7B-613CB6C9BFF3 # test only

Slack

Organizations who rely on Slack for collaboration and team communication can be easily disrupted by a breach. Our algorithms are sensitive to both web hooks and tokens used on the platform. Given all the potential integrations among Slack, AWS, and source control, the Security for Bitbucket algorithms can plug significant vulnerabilities by detecting access credentials for all three.

Slack Webhook

PY

hook = "https://hooks.slack.com/services/Txxxxxxxx/Bxxxxxxxx/xxxxxxxxxxxxxxxxxxxxxxxx"

Slack Token

PY

token = "xoxo-523423-234243-234233-e039d02840a0b9379c"

JS

const tok = "xoxa-2-511111111-31111111111-3111111111111-e039d02840a0b9379c"

Mailchimp

Security for Bitbucket Server identifies and intercepts commits that contain API keys for either Mailchimp or Mailgun.

API Keys

JS

MAILCHIMP_API_KEY = "a2937653ed38c31a43ea46e2b19257db-us2"

JS

# Using 343ea45721923ed956e2b38c31db76aa-us30 for this campaign

Mailgun

API Key

JAVA

MAILGUN_API_KEY = "key-eg8f02fb71f9ee886e96588013241ca0"

Private Keys (SSH, PGP, etc.)

Accidentally committing SSH private keys can leave critical production systems wide open to attackers. It's an easy mistake to make, as private and public keys are generated together and often reside in the same directory on a developer's machine. Security for Bitbucket scans for private keys in incoming commits and blocks the corresponding commits.

PayPal Braintree

Access credentials for direct interaction with Fintech are a particular priority. Our algorithms detect and block Braintree access tokens used in PayPal and block any commit that contains them.

Braintree Access Token

JAVA

PAYPAL_BRAINTREE_ACCESS_TOKEN = "access_token$production$696htvk3y5xcfnsn$42cde001d7a240d98ded578b4c1321c9"

Square

The Square API uses both personal and OAuth access tokens. Our application detects and blocks both.

Access Token

JS

SQUARE_ACCESS_TOKEN = "sq0atp-ZHE5_L-3DJZ9Ti7iDEADBEEF"

OAUTH Secret

JS

SQUARE_OAUTH_SECRET = "sq0csp-mE0eOD3rS7WsHFXSu2gU9DPumSr2r1AImSdjIkuyza8"

Stripe

Stripe is often cited as the reference standard API for its structure and documentation. Given its wide use, there's an elevated likelihood that Stripe API keys are already embedded in your source deck or supporting files. Our application detects variations on the Strip API key format, and intercepts them before they can be committed to Bitbucket.

API Keys

JS

STRIPE_API_KEY = "sk_live_ReTllpYQYfIZu2Jnf2lAPFjD"

stripe_creds = "rk_live_5TcWfjKmJgpql9hjpRnwRXbT"

Twilio

Twilio is another API that's in wide use. The Security for Bitbucket algorithms can spot both its API keys and Account IDs, and prevent them from being pushed to your source code repository.

API Key

JS

	TWILIO_API_KEY = "SKxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

Account ID

JS

	TWILIO_ACCOUNT_ID = "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

URLs with embedded credentials

During testing, passwords can be directly embedded in URLs to facilitate fetching protected resources. These can then be inadvertently committed to your code repository.

Password in URL

PY

response = urllib2.urlopen('https://username:password@myservice.com')
