CVE-2020-2016
Last modified
CVE-2020-2016 is a high-severity vulnerability rated 7/10 on the CVSS scale. 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. EPSS estimates a 0.57% chance of exploitation in the next 30 days.
