VMware vCenter Server Information Disclosure Vulnerability — VMware vCenter Server contains an information disclosure vulnerability in the VMware Directory Service (vmdir) when the Platform Services Controller (PSC) does not correctly implement access controls. Successful exploitation allows an attacker with network access to port 389 to extract sensitive information. Listed in the CISA KEV catalog (added 2021-11-03) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~90%. Treat it as real and prioritize remediation over triage.
- 0
Required action for VMware vCenter Server: Apply updates per vendor instructions. CISA set a federal remediation due date of 2022-05-03. After patching, verify the vulnerable path is no longer reachable before closing the finding.

The previous default setting for Airflow's Experimental API was to allow all API requests without authentication, but this poses security risks to users who miss this fact. From Airflow 1.10.11 the default has been changed to deny all requests by default and is documented at https://airflow.apache.org/docs/1.10.11/security.html#api-authentication. Note this change fixes it for new installs but existing users need to change their config to default `[api]auth_backend = airflow.api.auth.backend.deny_all` as mentioned in the Updating Guide: https://github.com/apache/airflow/blob/1.10.11/UPDATING.md#experimental-api-will-deny-all-request-by-default

An authentication bypass in Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to gain PAN-OS administrator privileges to perform administrative actions, tamper with the configuration, or exploit other authenticated privilege escalation vulnerabilities like CVE-2024-9474 https://security.paloaltonetworks.com/CVE-2024-9474 . The risk of this issue is greatly reduced if you secure access to the management web interface by restricting access to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 . This issue is applicable only to PAN-OS 10.2, PAN-OS 11.0, PAN-OS 11.1, and PAN-OS 11.2 software. Cloud NGFW and Prisma Access are not impacted by this vulnerability.
