D-Link DIR-890L UART Port rgbin hard-coded 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
0.78% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 55.9% of scored records. A rank, not a probability.
NVD base score
5.2 (CVSS v4.0), scored by the NVD independently of the CNA.
