Ripple20, set of vulnerabilities inside Treck / KASAGO IP Stacks


  • Ripple20 is the codename to a set of 19 vulnerabilities discovered by the cybersecurity team JSOF.
  • These vulnerabilities are inside an IP stack, selled under two different names (Treck TCP/IP for U.S market Kasago TCP/IP, for Asia market. -These two stacks were bought and used under privated-labeled by several softwares companies, some known names are: GHnetv2, Kwiknet, Quadnet.
  • But there's more, these stacks were also integrated, sometimes with modifications, inside several RTOS (real-time operating system).
  • Last, some of the vulnerabilities, depending the device operating system, configuration or location can have greater or lower CVSS score.
  • My advice is for companies to ask their suppliers if they use one of this stack and assess the risk following their company risk policy.
  • This will not be an easy set of vulnerabilities to patch, sadly.
