02 Description

Kieback&Peter DDC4000 Series Use of Weak Credentials

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 ImpacttotalSuccessful exploitation gives total 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
0.44% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 38.1% of scored records. A rank, not a probability.
NVD base score
9.3 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

Kieback&Peter DDC4002, DDC4100, DDC4200, DDC4200-L and DDC4400 controllers are considered End-of-Life (EOL) and are no longer supported. Users operating these controllers should ensure they are operated in a strictly separate OT environment and consider updating to a supported controller. Kieback&Peter recommends users update to DDC4002e, DDC4200e, DDC4400e, DDC4020e and DDC4040e controllers. Kieback&Peter recommends all affected users contact their local Kieback&Peter office to update the firmware of the supported DDC systems to v1.21.0 or later.
