As technology adoption has shifted to be employee-led, just in time, and from any location or device, IT and security teams have found themselves contending with an ever-sprawling SaaS attack surface, much of which is often unknown or unmanaged. This greatly increases the risk of identity-based threats, and according to a recent report from CrowdStrike, 80% of breaches today use compromised

By Deeba Ahmed An attacker with access to a Kubernetes cluster could chain two vulnerabilities in Google Kubernetes Engine (GKE) to escalate privileges and take over the cluster.

### Impact All Hail Batch clusters are affected. An attacker is able to: 1. Create one or more accounts with Hail Batch without corresponding real accounts in the organization. For example, a user could create a Microsoft or Google account and then change their email to "[email protected]". This Microsoft or Google account can then be used to create a Hail Batch account in Hail Batch clusters whose organization domain is "example.org". In Google, this attack is partially mitigated because Google requires users to verify ownership of their Google account. However, a valid user is able to create multiple distinct Hail Batch accounts by creating multiple distinct Google accounts using email addresses of the form "[email protected]". In Microsoft, this attack requires Azure AD Administrator access to an Azure AD Tenant. The Azure AD Administrator is permitted to change the email address of an account to any other email address without verification. An ...

### Impact In versions of the proxy from `2022-09-05` onwards (since 8c874c2ff3d503ac20c7d32f46e08547fcb9e23f), expired authorisation tokens could be renewed automatically without checking their validity against the original account configuration (i.e., the password that was set up when first configuring the account). An attacker with knowledge of valid account addresses and careful timing (i.e., attempting to log in during a period from 10 minutes prior to the token expiry time, but before a genuine login request is received) could use this issue to gain access to an account. This issue is not a concern if you only use the proxy on a local device. It is also not an issue if you are using the O365 resource owner password credentials grant (ROPCG) flow. If you use the proxy in a publicly-accessible setting (i.e., it is available from the internet or another network), you should upgrade to version [`2023-12-19`](https://github.com/simonrob/email-oauth2-proxy/releases/tag/2023-12-19) i...

### Impact _What kind of vulnerability is it? Who is impacted?_ Original Report: > The Oauth1/2 "state" and OpenID Connect "nonce" is vulnerable for a "timing attack" since it's compared via regular string > comparison (instead of `Yii::$app->getSecurity()->compareString()`). Affected Code: 1. OAuth 1 "state" https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth1.php#L158 3. OAuth 2 "state" https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OAuth2.php#L121 4. OpenID Connect "nonce" https://github.com/yiisoft/yii2-authclient/blob/0d1c3880f4d79e20aa1d77c012650b54e69695ff/src/OpenIdConnect.php#L420 ### Patches _Has the problem been patched? What versions should users upgrade to?_ TBD: Replace strcmp with `Yii::$app->getSecurity()->compareString()`). ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ not as far as I see....

### Impact _What kind of vulnerability is it? Who is impacted?_ Original Report: > The Oauth2 PKCE implementation is vulnerable in 2 ways: > 1. The `authCodeVerifier` should be removed after usage (similar to 'authState') > 2. There is a risk for a "downgrade attack" if PKCE is being relied on for CSRF protection. ### Patches _Has the problem been patched? What versions should users upgrade to?_ 2.2.15 ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ not known yet. ### References _Are there any links users can visit to find out more?_

Microsoft is warning of an uptick in malicious activity from an emerging threat cluster it's tracking as Storm-0539 for orchestrating gift card fraud and theft via highly sophisticated email and SMS phishing attacks against retail entities during the holiday shopping season. The goal of the attacks is to propagate booby-trapped links that direct victims to adversary-in-the-middle (AiTM
