Missing authorization in the JSON-RPC web services interface
of Extreme Networks Switch Engine (EXOS) allows an authenticated,
low-privileged (read-only) user to execute CLI show commands that are
restricted to that role through the command line interface. Successful
exploitation results in disclosure of sensitive information, including the
device configuration and the password hashes of local accounts. Configuration,
enable, and debug commands are not affected.
Disclosed password hashes can be
attacked offline, and a weak password could lead to administrative access to
the device. This issue is fixed in Switch Engine 33.7.1-patch1-11,
33.1.100.133-patch1-9, and 32.7.4.15-patch1-11. Extreme Networks would like to thank Toàn Lê (GitHub: https://github.com/toanln-cov) for responsibly disclosing this vulnerability and for working with our PSIRT team through coordinated disclosure.
