- 漏洞讨论

The Lucent RADIUS implementation is a user authentication software package designed to offer enhanced security services to users needing remote access to various resources. The package is no longer maintained by Lucent, and is public domain.

Numerous buffer overflows have been discovered in the package, which could allow a user to exploit the radius daemon. The radius daemon by default runs as UID root. A remote user may be able to overwrite stack variables, including the return address.

This makes it possible for a remote user to execute arbitrary code, and potentially gain local root access.
