Tenda AC23 SetStaticRouteCfg sscanf buffer overflow

03 Exploitation and scoring

Exploitation
Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
SSVC decision
  • ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
  • 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
0.81% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 56.9% of scored records. A rank, not a probability.
NVD base score
7.4 (CVSS v4.0), scored by the NVD independently of the CNA.
