High severity with no evidence of exploitation so far.
What to do
- Update designjet_t520_24in to axp2cn2331ar or a later version.
- Update designjet_t120 to axp2cn2331ar or a later version.
- Update designjet_t520_36in to axp2cn2331ar or a later version.
- Read the advisory on support.hp.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.
