High-Severity Vulnerabilities Discovered in ...
The vulnerabilities—the same across all nine stacks—involve the manner in which the so-called Initial Sequence Number (ISN) is generated. The ISN ensures that every TCP connection is unique, that there are no collisions with other connections, and that no third party can interfere with an ongoing connection. To guarantee this, the ISN is randomly generated so no one can guess the number and use it to hijack an ongoing connection or spoof a new one. Forescouts analysis showed problems with t...
