Title: NT Null Session Admin Name Vulnerability
Severity: MODERATE
Description:
By establishing a Null session with an NT host, an intruder can gain the name of even a renamed Administrator account. This is because even Null sessions are added to the Everyone group for the duration of the connection. This was done so that hosts not in the domain could still use MS Networking's browser functions.
