A race condition due to insecure creation of a file in a temporary directory vulnerability in PAN-OS allows for root privilege escalation from a limited linux user account.
This allows an attacker who has escaped the restricted shell as a low privilege administrator, possibly by exploiting another vulnerability, to escalate privileges to become root user.
This issue affects:
PAN-OS 7.1 versions earlier than 7.1.26;
PAN-OS 8.1 versions earlier than 8.1.13;
PAN-OS 9.0 versions earlier than 9.0.6;
All versions of PAN-OS 8.0.
|9.0||< 9.0.6||>= 9.0.6|
|8.1||< 8.1.13||>= 8.1.13|
|7.1||< 7.1.26||>= 7.1.26|
CVSSv3.1 Base Score: 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)
This issue is fixed in PAN-OS 7.1.26, PAN-OS 8.1.13, PAN-OS 9.0.6, PAN-OS 9.1.0, and all later PAN-OS versions.
PAN-OS 8.0 is now end-of-life as of October 31, 2019, and is no longer covered by our Product Security Assurance policies.
This issue affects the management interface of PAN-OS and is strongly mitigated by following best practices for securing the PAN-OS management interface.
