An authenticated file deletion vulnerability in the Palo Alto Networks PAN-OS® software enables an authenticated attacker with network access to the management web interface to delete certain files as the “nobody” user.

this includes limited logs and configuration files but does not include system files. The attacker must have network access to the management web interface to exploit this issue. You 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 critical 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 affects Cloud NGFW. However, this issue does not affect Prisma® Access software.
