An uncontrolled resource consumption vulnerability in Palo Alto Networks PAN-OS allows for a remote unauthenticated user to upload temporary files through the management web interface that are not properly deleted after the request is finished. It is possible for an attacker to disrupt the availability of the management web interface by repeatedly uploading files until available disk space is exhausted.
This issue impacts:
PAN-OS 8.1 versions earlier than PAN-OS 8.1.16;
PAN-OS 9.0 versions earlier than PAN-OS 9.0.10;
PAN-OS 9.1 versions earlier than PAN-OS 9.1.4;
PAN-OS 10.0 versions earlier than PAN-OS 10.0.1.
|PAN-OS 10.0||< 10.0.1||>= 10.0.1|
|PAN-OS 9.1||< 9.1.4||>= 9.1.4|
|PAN-OS 9.0||< 9.0.10||>= 9.0.10|
|PAN-OS 8.1||< 8.1.16||>= 8.1.16|
CVSSv3.1 Base Score: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
Palo Alto Networks is not aware of any malicious attempts to exploit this vulnerability.
This issue is fixed in PAN-OS 8.1.16, PAN-OS 9.0.10, PAN-OS 9.1.4, PAN-OS 10.0.1, and all later PAN-OS versions.
This issue impacts the PAN-OS management web interface but you can mitigate the impact of this issue by following best practices for securing the PAN-OS management web interface.
