PAN-OS: Improper Ownership Management
CVE-2024-3383 is a critical-severity improper ownership management vulnerability in PAN-OS from Palo Alto Networks, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 11.0.3, 10.2.5, 10.1.11 as the first without the flaw, so updating PAN-OS to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.58% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update PAN-OS to 11.0.3 or 10.2.5 or 10.1.11, whichever matches your release line, or a later version.
- Read the advisory on security.paloaltonetworks.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
