Server-Side Access Control Bypass vulnerability in WombatDialer before 25.02 could allow unauthorized users to potentially call certain services without the necessary access level. This issue is limited to services used by the client (not the general-use JSON services) and requires reverse engineering of the proprietary serialization protocol, making it difficult to exploit.Show less

An authentication bypass in the Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to bypass the authentication otherwise required by the PAN-OS management web interface and invoke certain PHP scripts. While invoking these PHP scripts does not enable remote code execution, it can negatively impact integrity and confidentiality of PAN-OS. You can greatly reduce the risk of this issue by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practices 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 does not affect Cloud NGFW or Prisma Access software.Show less
