03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.30% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 22.5% of scored records. A rank, not a probability.
NVD base score
4.3 (CVSS v3.x), scored by the NVD independently of the CNA.

07 Remediation

Zebra Printers running Link-OS v6.0 and later have a protected mode that protects the printer from this vulnerability. Activating this mode disables unauthorized changes and locks the current configuration until an administrator authorizes updates. By default, the secure mode is disabled as it is necessary to generate a password first. NOTE: the ZT410 industrial printer was discontinued on Oct 1st, 2020. The service and Support discontinuation dates are in September and December 2025 depending on region. Further information regarding security settings and best practices, including “Protected Mode”, can be found in the references. UPDATE: The vulnerability has been fixed by Zebra. The updated firmware version is Link-OS v7.3 which was released March 2025. The currently released version is Link-OS v7.4 which includes the fix that was released in the previous version.
